I was reading a post on Facebook relating to shark and impact of temperature on their migration and behavior and this got me thinking about temperature and fishing prospects. The post was at first relating to blue shark and if the recent beast from the East would delay the start of the shark fishing season off Cornwall. Anglers commented that the optimum temperature for blue shark to feed is around 13 degrees. Porbeagle shark are apparently less affected by temperature and can be found throughout the year around our coastline.

I used to consider grey mullet a fish of the summer months yet we now catch them all year. Does the cold water temperature stop them feeding. I often fish a local venue where the mullet are clearly visible and ignore baits for the majority of the time. They do this all year yet when I fish in winter I blame water temperature. Is this relative? With heavy snow melt dropping the water temperature I would feel success unlikely but will a rise in temperature trigger feeding even if the water rises to a temperature that is still low for the time of year.
A bitter east wind is undoubtedly bad for fishing but why? The temperature of the water does not drop that quickly so why is it so poor for fishing?
Each species we fish for is impacted upon differently by water temperature. Water temperature can impact upon both feeding, migration and breeding. It is this complexity that makes angling so fascinating. Whatever we fish for water temperature impacts upon the behavior of the fish we seek. Each species has its own niche of coarse and we think of winter cod and summer bass. We consider mackerel a fish of summer yet I saw some caught in Norway where water temperatures are far lower than South West England even in mid July when we were there.
In lakes we now catch carp all year and these were once a fish of the summer months. The reason we catch carp all year round is of coarse twofold in as much that we fish for them and expect to catch them. They have more food and are kept more active by anglers fishing for them.

I have perhaps rambled around a bit casting a few thoughts with no real direction in relation to water temperature and fishing but then that’s what anglers do at times just think of fish and fishing. Temperature is a big factor in fishing for many reasons. For my own sake I say roll on summer but how much does it impact upon the fish we seek?
Its seems that spring is slow to arrive and just as we think its getting milder another cold snap is forecast. But any day now we will get that first real day of spring when warmth prevails and balmy air descends.
There are of course signs that spring is here as daffodils, primroses and celandine’s line the hedgerows and roadside verges. Frogs spawned a couple of months ago now and their spawn is already transforming into tadpoles. It will be soon be the turn of the toads to converge onto lakes and ponds their birdlike croak echoing around. Any time now we could glimpse that first sand martin and then that true harbinger of spring and summer the swallows.
As anglers we are of course very aware of nature that is around us and this is all part of what fishing is all about. I am always filled with optimism as the days grow longer and the chance to fish evening sessions in daylight arrives. Of course many plans are made and time is as ever less plentiful than desired. In just a couple of weeks the clocks spring forward.
There will be the chance to cast a fly across the river for spring salmon. Flick a dry fly upstream for wild brown trout or fish a buzzer on a Stillwater for hard fighting rainbows.
Carp anglers will relish the warming water knowing that carp will become more active and as a result will search for food maybe even coming onto the surface where a chum mixer will be slurped down with that delightful sound of summer evenings.
If you’re a sea angler your thoughts will be turning to bass, smoothound and ray. It will of course depend upon your favourite angling style what you seek. The bait angler will enjoy sitting back waiting for the nodding rod and screaming reel. The lure fisher will be more mobile searching for fish casting here and there searching for that electric tug on the line.
I could ramble on but I am sure you get the vibes that I am trying to convey that excitement at the arrival of new a season and fresh piscatorial adventures. I hope to report on your catches over these coming months, not just the fish but also an appreciation of all that angling means. So please feel free to send me your successes, stories and any images of the angling world you enjoy.
Many thanks go to those who sponsor this site and support this project.
I occasionally receive emails from members of the public in relation to my weekly angling column and always try to answer in a polite and informative matter. I recently received the below email from Robert Durrant a non-angler who has undoubtedly taken an interest in my weekly column. His inquiry relates directly to sea angling and the killing of fish. I will let you read through the exchange of emails below and I will add a few comments at the end.
Wayne, Every week in the Journal you write about vast numbers of fine fish, targeted for sport and brought to weigh-ins. Many are species of shark which are endangered and protected. Are all of these fish bought dead to the scales, or have these anglers moved into the 21st century and found ways to weigh specimens at point of catch without harming them and then releasing them live and unhurt back to the sea? I wish you’d write more about such practices. Best wishes, Rob
Hi Rob,
Thank you for inquiry and prompting me to give more coverage on angling practices in relation to catch and release. Angling has progressed a long way in recent years and catch and release has become the predominate practice for all angling disciplines. In relation to shark the larger species are all returned alive to the water and in some instances are tagged to enable scientific research to track migration routes. Sadly many of the blue shark tagged are recaptured by long-liners in foreign countries where the fish are targeted for making sharks fin soup. Spurdog numbers have increased dramatically in recent seasons as a result of a commercial ban on the species and all of those caught by boat anglers are returned alive.
Fortunately the practice of bringing dead fish to the scales is becoming a thing of the past with most anglers happy to weigh and return fish after a quick photo. You will notice that the vast majority of pictures I use for the Journal are on location and the fish returned alive. There are sadly a few clubs that have weigh ins where fish are brought to the scales due to a lack of trust amongst members. I do not think this will continue for many more years.
Salmon anglers now return over 90% of salmon caught, with no fish retained before June 16th. Bass are now catch and release only for recreational anglers, though this may be reviewed later in the year if scientific data determines it is possible.
I have no problem with anglers retaining the occasional fish for the table if stocks are healthy. But I have no time for killing fish for competition purposes.
I will write about the changing practices in a future Journal column and on my website. I do not know if you are an angler or have ever fished but I would point out that angling does engage people with the countryside and many anglers are keen conservationists who have a deep love of nature.
Best Regards,
Wayne
Hi Wayne,
Thanks so much for your courteous, informative, and encouraging reply, greatly appreciated.
It would be great if you could give more coverage to the enlightened practices followed by ethical anglers these days, as so much emphasis is given to weights and trophy specimens that it often seems that conservation of species and fish welfare comes a very long way behind.
I’m delighted that we see eye to eye about avoiding killing fish except for table use where the stocks are healthy.
I’m not an angler, though of course I’ve enjoyed a little sea fishing in my earlier years; but my interest stems from a particular awareness of marine conservation issues, where I have some involvement, from recording marine species found from the shore, and from diving. I’m very much aware of tag and release practices involving sharks, but little is ever mentioned about this in the media regarding local practices, or indeed in the publicity put out by local sea fishing operators. Maybe it’s just taken for granted; but it would be good to see greater emphasis on conservation and environmental issues.
Yes, I have noticed that most of the photos you use in the Journal do show the fish displayed apparently close to place of capture, but without confirmation that these specimens are not later hauled away to the scales elsewhere, it was difficult to be confident. Certainly friends of mine who have been involved with sea fishing clubs in the past have been nauseated at the pointless waste and indeed cruelty involved in these inland weigh-ins which used to be standard practice. I’m so pleased that in recent years things have moved on.
I hope that an emphasis on decent practices will help make those benighted clubs which still insist on weighing dead fish at the club’s scales realise that they have become social pariahs, whatever happened in the past and too often still happens overseas.
I look forward to reading your comments in the Journal, and your website too.
Thanks again for your very positive response.
All the best, Rob
Hi again, Wayne,
Just been looking on the North Devon Angling News site. Lots of pics there of sea catches displayed on the beach or in the boat, but too many not good – one on top of the harbour wall at Clovelly, eg – particularly lots of sharks being dangled by their tails. Shark Trust handling guide very strongly emphasis that sharks must never be held up by their tails alone, and abdomen must always be supported. Otherwise, though the shark may be able to swim away after return it may very well die out of sight from internal injuries.
Maybe you could put out a warning that you will cease publishing pics showing bad practices? Would be a brilliant idea if boat skippers showed a bit more responsibility in guiding their clients correctly!!
All the best, Rob
Hi Robert,
Thank you for your reply. Following on from our exchange of letters would it be possible for me to post the letters on my website followed by a brief article on conservation practices and changing times. I think using the exchange of emails would give a good introduction to the feature and demonstrate to anglers how non anglers view what appears in the media, It might also make people think a little more deeply. This will have more impact than me simply stating my views.
Best Regards,
Wayne
Hi Wayne,
Certainly very happy for you to do that, sounds a good plan.
I look forward to it.
Cheers, Rob
I am an all round angler and fish for species in all disciplines of angling and I can understand Rob’s concerns to an extent as sea angling is to some degree less focused on fish welfare than Coarse and carp anglers. To some extent this is due to the fact that Coarse Fish and Carp are valuable commodities stocked into lakes that cost the fishery owners considerable sums of money. For this reason fisheries have strict rules to safeguard the welfare of the stocks. The use of unhooking mats, antiseptic solution to prevent infection, safe rigs, barb-less hooks and the sterilization of equipment prior to fishing is common practice.
Anglers also embrace good handling practice because they value the fish and have a respect for their quarry. I fish for pike and know a good number of pike anglers who are very passionate about the pikes welfare preaching the use of correct tackle and the care needed to safely remove hooks.
Game Fishers who fish for salmon and sea trout now return the majority of fish caught and get very involved in protection of river habitat and even run hatchery projects to attempt to halt the decline in stocks of wild salmon and sea trout. When I first fished for salmon over thirty years ago the majority of salmon were kept for the table and I delighted in feasting on a wild salmon caught from a local river. I always felt a tinge of sadness though after administering the last rites and seeing the vivid colours of life drain from the vibrant flanks. Today I take far greater pleasure in seeing the occasional salmon I manage to tempt swim strongly away to hopefully complete their Journey to the spawning grounds.
Sea angling I concede has been slower to move towards catch and release practice in part I suspect down to the vast and wild nature of the sea and the once misguided perception that fish stocks are not impacted upon by angling. There is only one reason to kill fish and that is to eat it. At this point I will confess that I used to fish in local angling competitions and dispatch fish to bring back to the weigh in. I also killed fish to submit for specimen trophies. As time passed I and many other anglers grew concerned at this unnecessary slaughter. The Sea Angling Club that I have fished with over the past forty years now practices catch and release for all competitions. In modern times with quality scales and modern digital cameras and phones there is no reason to kill fish except for the table. Images of live fish at the waters edge are far more rewarding than a dead corpse held aloft in the garden or in a club house.
A quick photo of a smiling angler and this bass is released back to the estuary
As a child I gazed in wonder at the corpses of dead blue shark at Looe in Cornwall brought ashore by members of the Shark Angling Club of Great Britain. This club is now 100% catch and release promoting responsible angling practice that minimizes mortality of these magnificent fish. I have fished for shark on numerous occasions and thrilled at the power of these fish on the line. I have enjoyed the privilege of interacting with the shark and delighted in seeing them swim away. In some instances shark are tagged and this has proved valuable in scientific research tracking the vast migration taken by sharks. Sadly many shark are recaptured by commercial long liners who target the fish for use in shark fin soup.
Wasted carcasses on the quay – Looe in the 1960’s
Whilst sea angling has moved towards conservation there is room for increased awareness of good handling practice. Thought can be given to tackle used with circle hooks sometimes beneficial in reducing deep hooking. Tackle used should always be strong enough to give a good chance of landing the fish hooked. Fish should be weighed in a suitable bag or weigh sling and not hung up by the gills. When holding the fish for a picture it should be handled firmly and supported to reduce risk of damage to internal organs.

As anglers we have a responsibility to show respect for the fish we seek to catch and to always show the pastime in a positive light. We should not judge past generations by today’s standards. Perceptions change and as we realise the fragility of the natural world we adopt more enlightened practices. I have always been a passionate angler and believe interaction with nature via angling has given me a deep bond with the natural world and an appreciation of the great outdoors. Angling in general is a healthy sport, good for both mental and physical health and an important social pastime that also bring huge financial rewards to local business via angling tourism.
Footnote –
Hi Wayne,
Thanks for the reference in your article this week, linking to the great article in your blog, which I found very helpful; and I most grateful to you for the very positive way you have responded to my approach to you. I am sure that many readers will be encouraged by what you have written; and I hope that it will nudge angling practices a bit further in the right direction.
Steve Dawe tells us about his Fishty two Challenge a very worthwhile cause and one I am sure many reading this will be able to relate to.
It was a huge shock when I found out that a good angling friend of mine had suffered a massive stroke only a week after our last fishing trip together, this particular stroke has left friend Andy, wheel chair bound and in need of a full time carer. My father had also suffered a mini stroke around the same time and the two instances really highlighted just how indiscriminate and instant a stroke can be. With friend Andy determined to get fishing again and suffering the pain and frustration required to rebuild his life, I felt inspired to try and do something. This is when the concept of the Fishty Two challenge was formulated and as an added bonus this year is to be my 52nd birthday. The challenge is set across the 52 weeks of 2018 commencing on January the 1st and concluding on December the 31st. During the year I need to catch 52 different species of fish from Sea, Freshwater and Game fisheries and all on a catch and release basis.
The charity I am raising money and just as importantly awareness for is the Stroke Association, a national charity that supports victims of strokes and their families. When I approached the charity with my idea they were really excited at the uniqueness of the idea and offered as much support as I needed. The next issue I had was setting up a web page, twitter account and just giving page all massive hurdles for a technophobe, time to enlist the help of my daughter who quickly sorted it all with a few dozen clicks. The definitive list of species is still a close guarded secret and I have even gone to the trouble of colour coding them green, amber and red with the red species being the most difficult. Much of my angling is on the north Devon coastline either boat angling or shore fishing but during this challenge I will be travelling the length and breadth of the country after species not indigenous to the west country.
The great thing with anglers is that when a fellow angler needs some help we step up and offer a hand, this is indeed the case with my challenge with many angling friends offering assistance so I can be in with the best chance possible to catch a particular species. So far I have raised nearly £400 and my target is £552 so it’s a fantastic first month, species wise I am on 17 and these are split between sea and coarse species. The easier species can be knocked off fairly quickly but the harder ones may take many trips so the more I have in the bag the better. Fishing from North Devon in January I landed, Spurdog, Dab, Dogfish, Conger, Whiting, Rockling and Bullhuss highlighting just how great our coastline really is. The challenge has been very enlightening from an angling perspective and even the smallest of a target species is met with much rejoicing. Sadly since starting the challenge at least three of my angling friends or their families have had their lives affected by strokes, it does appear that the average age of a stroke victim has come down, a worrying trend.
I have a website showing the gallery of fish, info on the stroke association and where to donate if you so desire, I also do a weekly blog which is also accessible from a tab on the web page. The webpage link is https://stevedawe189.wixsite.com/fishtytwochallenge
Hopefully the rest of the year will be successful and I’m banking on North Devon to throw up a few more of those needed species, thanks to everyone who has supported me thus far and to all those who will be soon.
The North Devon Coast is a dangerous location especially during the winter months and keen sea anglers live on the edge. Despite plenty of warnings of the dangers of the sea events make the news every year some of them tragic. I have with kind permission of the Ilfracombe RNLI repeated their latest news post from social media.
In the early hours of Tuesday morning both boats were launched to the assistance of three fishermen cut off near Sandy Cove, Combe Martin.
The pagers sounded at 1.25am and the volunteer crew soon mustered to launch both boats despite a frosty start for their vehicles. The All Weather Lifeboat, The Barry and Peggy High Foundation and our Inshore Lifeboat, The Deborah Brown II, made their way to Broad Sands beach and soon located the casualties.
All three were caught out by the tide, although experienced fishermen they had underestimated the rise of tide, and a 1.5m swell was running in choppy seas. When realising their difficulty one took the decision to raise the alarm but with no phone signal, he moved across the rocks and was taken into the water by the swell. The casualty was wearing a flotation suit but had a backpack and waders on, so had a struggle to free himself. He managed to kick off his waders but was battered on the rocks, he then wrestled to make his way to land and picked up a phone signal to call the Coastguards and raise the alarm.
The Ilfracombe Coastguards brought him back to Ilfracombe Lifeboat Station, while his two friends were picked up by the Inshore Lifeboat and transferred to the All Weather Lifeboat, and taken back to Ilfracombe Lifeboat Station.
The injured casualty said ‘ I never imagined I’d end up in the water and had serious concerns for my safety’
These anglers normally carry vhf but felt it was such a good evening it wasn’t worth carrying. Also mentioning that 112 can be picked up more easily would be advantageous. The casualty had to climb to the main road barefoot to get a call out.
The Coastguards administered first aid and the casualties were picked up for home. Volunteer Second Coxswain Carl Perrin said ‘ it was a very favourable outcome which could have been so easily a far worse result’
Both boats were back and ready for service at 3.45am.
If we are honest most experienced sea anglers have had a few close calls. There are always lessons to be learnt and one of those has to be knowledge of the tide and weather conditions. I know Outer Stone Broadsands well and have fished there many times. It is a low water mark that I would only fish during settled conditions. Access is via a gulley that dry’s out for a short time over low water. An observation I would make is that it is easier to cross the gulley as the tide drops but far more difficult to get back if the water is at the same level on the flood. It is imperative that the rock is vacated in plenty of time as the tide floods.
The wearing of waders adjacent to deep water is questionable as falling in wearing these will make getting back to shore difficult. The wearing of flotation suits or aids is to be recommended but is not common practice. The carrying of a mobile phone to raise the alarm if all goes wrong is essential. The carrying of a lifeline is also a wise addition to the anglers pack. It is also unwise to fish alone. Always let someone know where you intend to fish and an approximate time of return.
The RNLI and Coastguard do a sterling job in rescuing those that get it wrong and are to be applauded.
I joined seven members of Bideford & District Angling Club at Clovelly this morning to carry out a beach clean of the foreshore and harbour area. Following issues with angling related litter Bideford Club were determined to show that anglers do care and condemn those who drop litter and tarnish the majority of anglers who do take their litter home. In all we collected 16 bags of rubbish of which I would estimate 1% was angling related. The vast majority of the litter was plastic and its long levity was illustrated quite starkly by this old Ski Yogurt pot that I googled to find it probably began its life in the mid 70’s.
Children’s plastic toys were also abundant along with plenty of household containers. Some of the debris has undoubtedly come from waste that had been dumped on the cliff-side by villagers in times gone by to be dislodged as the cliffs subside and the sea pounds the upper foreshore. Giving up a couple of hours to pick up the unsightly waste from the foreshore brings home the immensity of the plastic and waste issue that is caused by our modern lifestyle. There is a minority of anglers who add to this problem with their own debris but society has a big problem as could be seen as I drove home along the Atlantic highway with its littered verges.
Fishing line was amongst a small amount of angling related litter that included a couple of frozen bait wrappers.Litter picking
Plastics and other debris dislodged as the cliff subsides.
I am always on the look out interesting angling stories and thought this old film footage a fascinating glimpse into times gone by its all a bit barbaric by today’s standards but don’t judge past generations on today’s perceptions. This was remember a time when people had little perception of the vulnerability of the oceans believing that its wonders were inexhaustible.
I recently attended the Torridge and Taw River fly Celebration event at Newton St Petrock where we met up with members of the River Fly Monitoring Team. This hands on scheme has produced a wealth of valuable data that can give a valuable insight into the ecological state of our rivers. I have tried to collate some highlights from the data provided and will update when I receive news of forthcoming training events. For more information please visit;- The River Fly Partnership website :- www.riverflies.org
Email from Izzy Moser to those who attended the event.
Dear all,
Thank you for attending the Riverfly Celebration Event on Wednesday evening this week. It was really excellent to finally put some faces to names and there were a huge number of helpful discussions during the meeting, so thank you for this.
I have tried to list some of the main discussions in the notes below, but if I have missed anything, please do let me know and I will add it to the notes before circulating to the wider network.
Notes from Riverfly Taw/Torridge Event 10/01/2018:
1. There were discussions on incident reporting and what types of incidents should be reported to the Environment Agency Hotline. Volunteers were asked to report incidents with photo’s if they weren’t sure to their local Wildlife Trust or Rivers Trust. The Environment Agency Hotline Number is for incident reporting: 0800 80 70 60.
2. Volunteers requested a list of sites that would be high priority for monitoring so that new volunteers can look to take on these sites.
3. Some volunteers expressed interest in occasionally surveying an additional high priority site instead of their usual site if their usual site is consistently achieving good invertebrate numbers. Thank you for this suggestion Geoff.
4. Discussions were had on the spread of sites and whether some volunteers may want to move their site to avoid being too close to an existing site. Volunteers should discuss any concerns with their Riverfly Co-ordinator.
5. Lots of discussions were had on how to get more volunteers involved in the Riverfly programme and how training only once a year is a limiting factor of the project. Discussions were had on whether more people could get trained to run the Riverfly Training Day. Ben Fitch offered to potentially help with training small groups (5-6 volunteers) if the Teign Training Event becomes fully booked.
Actions:
1. Please could everyone send any contact details of volunteers who may be interested in getting trained as a Riverfly Volunteer to Olivia for the River Taw [email protected] or to me for the River Torridge [email protected]. At the moment we are only aware of a small number of people interested in the training events, so for considering the running of future events, we need to know how many people are interested.
2. If you know someone who is interested in being trained as Riverfly trainer please do let me know and perhaps we might be able to look into getting more people trained, although we can’t guarantee anything.
3. If you have any concerns about your site, or would like to register a new site, please contact your Co-ordinator I.e. Olivia for the Taw [email protected] and me for the Torridge.
I have attached the details of the Water Framework Directive status for the River Taw and Torridge classifications. Under the column for ‘status’ it lists whether the catchment is in ‘poor’ or ‘moderate’ status. You can use the filter to also show catchments that are in ‘good’ or ‘high’ status. I have also filtered it so that it shows data from 2013-2016 in the ‘year’ column although you can look at data earlier than this if you want to by changing the filter. This should help you to pinpoint catchments that are higher risk for pollution in the ‘poor’ and ‘moderate’ category. From my knowledge of the River Torridge catchment, I am aware that the following tributaries have water quality issues: Dolton Streams, Iddesleigh Streams, River Mere upper catchment, River Mere lower catchment (already monitored), Whiteleigh Water (already monitored), Pulworthy Brook (already monitored), Dipple Water (already monitored), Bideford Yeo (already monitored) and Waldon (already monitored). Unfortunately I cannot give the same information for the Taw catchment, but hopefully the attached spreadsheet should help pinpoint some of the catchments with issues.
I am away next week so will not respond to any emails, but should be back on the 22nd and can answer any queries then.
Thanks once again for your support. It’s a real privilege to work with people who are passionate about their local rivers.
There is a need for more volunteers on the Taw system.

Thanks to all past, current and in advance,
future volunteers. We can do nothing without you.
A huge thank you to Matt Edworthy who completed his role as the Taw and Torridge Riverfly Co-ordinator in August. Matt has worked since 2014 to set up Riverfly on the Torridge and unfortunately had to pass it on in 2017. In the four years since it started the project has come on leaps and bounds and there are now also active sites on the River Taw.
Riverfly Report 2017
Background
Riverfly in the Torridge catchment was established in 2014, through a partnership with the North Devon Biosphere and Devon Wildlife Trust. It has been running now for 4 years and is one of the larger Riverfly projects in the UK, with 25 active sites in 2017 and over 40 registered sites. Since 2016, Riverfly volunteers have also been trained to monitor parts of the Taw catchment with 11 volunteers trained and 6 active sites.
The programme is almost entirely volunteer led and consists of a combination of anglers, conservationists and local river enthusiasts. It is designed to help detect pollution incidents through the identification of river invertebrates and the abundance of each group. This gives a score for each site which, if falls below the trigger level set for the site by the Environment Agency, proceeds with further action in the form of a second survey by the Catchment Coordinator or involvement of statutory bodies such as the Environment Agency. As well as detecting pollution events, the surveys can also monitor long-term changes in overall river health and act as a deterrent to polluters.
Riverfly National Review – From the Anglers’ Riverfly Monitoring
Initiative (ARMI) Project Manager
Whilst 2017 has been exceptionally busy for the Riverfly Partnership (RP), with a change of host in April and a strategic refocus of Anglers Riverfly Monitoring Initiative (ARMI) deliverables for this year, the ARMI network also has been in full flow. During the year to date, 54 ARMI training workshops have been delivered to 597 ARMI volunteers and £308,250 of in-kind ARMI coordinator and volunteer time has been committed alongside the rod licence funding which RP receives from the Environment Agency.
ARMI volunteers regularly monitor 1955 sites UK wide and continue to detect pollution incidents, reporting vital information to local statutory body contacts. Across the UK, strongly established ARMI hubs and groups are providing the spine to support Riverfly Plus, and other citizen science, initiatives, such as Extended Riverfly (siltation & low flows) and Outfall Safari (developed and first run by the Citizen Crane project in the Crane Valley catchment).
As always, my continued and sincere thanks to every single ARMI volunteer, coordinator, tutor and partner for your ongoing commitment to protecting and conserving our rivers across the United Kingdom. Special thanks to all rod licence paying anglers and the Environment Agency for providing funding support to ARMI in England, to SEPA for providing strategic support to ARMI in Scotland, to RP host the Freshwater Biological Association and to RP Chair, Steve Brooks.
Riverfly Report 2017
New Volunteers trained in 2016 and 2017 (Taw and Torridge)
In May 2016, nine new volunteers were trained at Hatherleigh Community Centre. For the first time, two volunteers who took part were the beginning of Riverfly in the Taw catchment. They purchased their own equipment and at the end of the season, one site was active (Nymet Rowland) and 3 samples were taken. During 2017, a second training event was held at the Fox and Hounds (Eggesford), with 11 volunteers trained including 9 new Taw volunteers as well as 3 new Torridge volunteers. There are now 6 active sites in the Taw catchment.

River Torridge
2017 update
The last Riverfly sampling for 2017 was done by the Torridge volunteers in October. Despite the difficulties accessing some stretches due to poor weather towards the end of the season, during the year, 103 samples were collected from 25 active sites. 3 new volunteers were trained up at the start of the season and 4 already registered sites were taken on by new volunteers, including Dymsdale Wood Bridge, Sutcombe Mill and Hatherleigh CC. Since Matt’s departure from the North Devon Biosphere in August, the Torridge Riverfly project has been taken on by Izzy Moser at Devon Wildlife Trust. Izzy can be contacted via email at [email protected].
Results
The data, which in some catchments has been collected for 4 years now, really shows either declining or improving river water quality across the Torridge catchment. Overall, the results show that 7 rivers have strongly improved since the start of Riverfly and 3 rivers have clearly declining water quality. Some patterns from tributaries are less clear with variable water quality throughout the survey period.
3 samples on two different tributaries; the Dipple Water and the Pulworthy Brook, failed their trigger level. The trigger level breach on the Pulworthy Brook which was reported in August was given an Environment Agency reference number. The stream has been assessed in previous years and is known to suffer from chronic low flow stress. The river was otherwise reported as healthy by the volunteer and additional surveys were not required.
The trigger level breach which occurred in the Dipple Water has also been investigated by Michael Thomas following previous trigger level breaches and is under investigation from known upstream impacts by Andrew Fuller, the local Environment Officer. Andrew carried out a site check shortly after the trigger level breach and investigations upstream are being carried out. The stream also suffers from low flow stress. For the full data, please see the separate PDF included with this document.

River Torridge Results since 2014
Looking at the Riverfly programme as a whole since it began on the Torridge in 2014,
547 samples have been taken
50 sites have been sampled
17 samples have fallen below trigger levels
24 sites are inactive at the end of 2017. A few of these sites have been taken up by newvolunteers, but if anyone wishes to get involved in Riverfly and possibly take up one of these
sites, please contact Izzy Moser at Devon Wildlife Trust via [email protected].

After the Riverfly training event on the 1st April, it was a little slow getting some sites registered and data collected, but by the end of the season, a total of 5 new sites were registered and 17 samples were collected. 5 sites are registered but currently inactive (table 4). Again, with the poor weather towards the end of the season, opportunities for collecting samples were limited. Since Matt’s departure from the North Devon Biosphere in August, the Taw Riverfly project has been taken on by Olivia Cresswell at Westcountry Rivers Trust. Olivia can be contacted via email at [email protected].
Results
There are now a total of 6 sites registered in the Taw catchment. Thankfully, none of the surveys delivered in 2017 breached the trigger level set by the Environment Agency, although 4 samples were near the trigger level. Data trends for catchments with more samples collected are starting to show, although additional data is required to show any long term changes in improving or declining water quality. For the full data, please see the separate PDF included with this document.
River Taw Results since 2016
Looking at the Riverfly programme as a whole since it began on the Taw in 2016,
20 samples have been taken
6 sites have been sampled
0 samples have fallen below trigger levels
4 sites are registered but currently inactive at the end of 2017.
Riverfly Schools Update
Riverfly schools ran again in 2017, delivered by Izzy Moser at Devon Wildlife Trust. The event involved 31 children from Bradworthy Class 6 surveying to identify Riverfly invertebrates as a method of detecting river health. A thank you to Bob Shepard who volunteered to help during the day.
Since Riverfly schools started in 2015, a total of 83 children have engaged with the event which is held at Julian’s Farm near Bradworthy. Unfortunately several events had to be postponed due to poor weather conditions.

Riverfly Report 2017
Riverfly Events have also been held at Hatherleigh Primary School and at the annual Hatherleigh Fair, delivered by Elizabeth Durrant (River Lew Riverfly Volunteer).
Professor Sir John Lawton Visit
In 2016 Professor Sir John Lawton, former head of the Natural Environment Research Council and President of the Institution of Environmental Sciences, visited the River Torridge Nature Improvement Area. As part of that he travelled to a Riverfly site, closely monitored by Gordon Murray during an invertebrate survey, to discuss the importance of Riverfly monitoring in the Torridge catchment. It was Sir Lawton’s Report entitled ‘Making Space for Nature’ which led to the development of Nature Improvement Areas, of which the Torridge catchment was one of 12 in England.

Freshwater Pearl Mussel Project Update 2017
This summer, the project achieved an exciting milestone. Thanks to our expert advisors from Ireland, we were able to confirm live juveniles mussels for the first time in over 50 years. The juvenile mussels which had previously encysted on brown trout dropped off at our captive rearing facility in North Devon. This enabled us to collect and return them to the River Torridge in specially selected locations. The captive breeding programme is currently in its second year, and during October 2017, the project was able to confirm a second year of successful glochidia (larvae) attachment on host fish.
This programme of work is part of the national ‘Restoring Freshwater Mussel Rivers in England’ funded by Biffa Award and co-ordinated by the Freshwater Biological Association. It is the first to trial this short- term breeding method in England.
Along with the captive breeding programme, the project delivers an array of measures to improve local water quality including tree planting, riverbank erosion management, tree coppicing, watercourse fencing, forestry track improvements, farm yard improvements, farm advice and workshops.

When I started fishing forty odd years ago fishing garments tended to consist of old clothes and at best outfits bought from the nearest Army Surplus store. Times have fortunately changed and angling clothing has come on a long way with specialist weather resistant clothing available that is both functional and smart.
A couple of years ago my good friend Kevin Legge introduced me to a local North Devon company based in Braunton that provides bespoke clothing for use in demanding environments. Reed Chillcheater Ltd specialise in garments for use in water sports such as kayaking. Kevin’s logic was that this quality equipment would be ideally suited to sea anglers who spend many hours exposed to hostile weather and conditions.
I recently enjoyed a visit to the shop floor where I met up with owner Chris Reed and Dion Hunt who gave me a fascinating tour of the premises and explained the intricacies and complexity’s of the manufacturing process and the properties of the materials used. Chris established the company in 1999 when they got off to a flying start winning the British Plastics Award for Aquatherm Fabric.

Aquatherm is a modern intelligent Fabric designed using basic practical science as Chris explained to me in layman’s terms. Wind and water is the enemy and are combated effectively using layering with Chillcheater’s Aquatherm providing the outer layer. The smooth outer surface is water resistant and drys quickly reducing wind chill that is caused by evaporation.
The most popular products for anglers have been the Aquatherm outdoor jackets with transpire fleece inner with matching storm trousers. I have had one of these jackets for close to two years and can vouch for its warmth and weather resistance both at home and abroad in Norway.
Extensive testing and consultation with anglers including North Devon’s local enthusiast Kevin Legge has resulted in a product that ticks many boxes. The Storm Jacket has several useful features including a fleece lined kangaroo pouch pocket to warm the hands, an Aquatherm outer pocket with a drain hole along with Velcro fastening, adjustable wrist straps to prevent water ingress and ¾” length zip that is made from hardwearing saltwater proof plastic. The storm peak is reinforced with wire; reflective strips give high visibility for added safety. All seams are fully heat taped to ensure no leakage.
The storm trousers are made of the same Aquatherm material with adjustable Velcro boot fasteners, shin guard overlay protection for knees, twin cargo pockets with drain holes, double Aquatherm bum patch, inner foam pouch phone pocket, elasticated back fix braces with simple double loop fasteners and elasticated top for close fitting.
Ideally beneath this robust outer layer can be worn transpire fleece inners. These are made using single filament yarns made from polyester and spandex. This ensures a tangled array of soft filaments that cling to the body matching the body’s contours trapping a warm layer to the skin. These fleeces can be purchased in either single layer suitable for the British Climate or in double layer for extreme climates like Norway and Iceland in winter!
Other items in the transpire fleece range include socks, long trousers, short trousers, long sleeve tops, zipped or unzipped tops, beanies and balaclavas.

Dion also showed me a Pertex jacket that can be worn over the inner layers or as an outer garment to repel wind and light rain. This amazingly lightweight material folds up into a bag no bigger than an apple!
Testament to the quality of the clothing produced at Chillcheater is the fact that renowned adventurer and long distance Kayaker Justine Curgenven has chosen the products for several of her expeditions in some very harsh climates.
I found the tour of Reeds fascinating and was very impressed with the attention to detail and the state of the art production techniques ensuring a top quality product. The venture into clothing aimed at anglers is a relatively new venture for the company that has for years focused primarily on providing robust, light weight and warm clothing for extreme water sports enthusiasts.

I discussed breathability and overheating with Chris who gave some sound advice regarding maintaining comfort whilst out fishing. Angling tends to be a rather sedentary pastime. I explained that one issue with fishing is that reaching the venue can require a considerable degree of excursion that can result in perspiration. This can then lead to the angler feeling cold as the session unfolds. Chris suggested that in many cases venting whilst in transit could significantly reduce this. So remove your hat and undo the zip. During long expeditions explorers cover ground slowly to reduce overheating. Plodding slowly to your chosen mark and taking five minutes longer to get there can significantly reduce perspiration and subsequent chilling. When you arrive at the mark you can of course zip up and put on the hat to keep the warmth in!
Chillcheater gear isn’t cheap but it is certainly quality gear that will outlast the majority of weather gear sold by other companies for anglers. For more information on Chillcheater visit their website www.chillcheater.com or give them a ring on 01271 815828.
