Latest news on the problems concerning fish deaths in the screw

Archimedes Screw, Durham - Acoustic Fish Deflector Installed

In order to prevent migratory fish entering the base of the Archimedes Screw in Durham City the Screw Operator, Durham County Council, have recently installed an acoustic fish deflector on the outlet of the turbine. The deflector will help guide migrating fish to the adjacent fish pass and away from the screw. This deflector, built and installed by Fish Guidance Systems, Southampton,  is augmented by an optical array. The acoustic deflector must be tuned in  intensity, frequency and position for optimal performance. It is therefore important if anyone sees fish in the base of the screw that this is reported immediately to the EA on their emergency number 0800 80 70 60 so that any incident is officially logged (this number iOS on the side of the turbine housing). It would also be helpful if a video of the incident could also be taken and please let WAA know about the incident.

Guest Permits

Whilst club secretary Dave Wilson can supply members with guest permits fairly quickly some members are leaving it fairly late when requesting a guest permit. While we do have a seven day rule for requests, Dave is fairly flexible on the rule, and we know members may make a last minute decision to go fishing would members please try to give more than one days notice, Your assistance will be appreciated.

May Fish Counts

The latest counts available for migratory fish running our northern rivers has been added today to the fish count section.

Salmon and Trout Conservation (Northumbria Branch)
 
Still Quiet
With the severe shortage of rain and none forthcoming by the looks of it then members are fishing our three stillwater fisheries. Reports show that members are having some excellent catches at all our stillwaters and we are pleased that as a club we can offer members alternativers when the rivers are low. Whilst the rivers are still low we can report that sea  trout are around in good numbers on the Till beats but are proving hard to catch.
 

May Update

Top of the Class

Congratulations to Member John Pape who has passed his AAPGAI in advanced salmon. Not certain if John will be prepared to offer lessons but if he does so decide we will let members know

 Sea Trout Scales samples
From FFF:  Dave Wilkinson, a member from Cramlington, has asked the Committee, and been granted, leave to seek the following from members. These words are his:-
 
 
" Simply put guys, I NEED YOUR SEA-TROUT SCALES PLEASE:-
 
I have Heads of Agreement from the National Oceanographic Centre at Southampton University ( NOCSU ) for them to run a research project into the diet of NE sea-trout (ST) and the areas where our sea-trout may feed - from scientific analysis of the scales, using latest methods* 1.
 
Research has been carried out for the Living North Sea Project ( LNSP ), but not in depth into the specific area which is now suggested: i.e. are our NE ST dependent upon sandeels to maintain a healthy stock; precise locations with the North Sea where our NE ST's forage ?
 
The backdrop to this suggested work is the restoration of the North Sea commercial sandeel fishery last year with a Total Allowable Catch (TAC ) of c 488,000 tonnes. About 90% of this TAC was granted to Danish boats working into the huge animal feed plant in Esbjerg, Denmark. Much of this plant's output ends up feeding farmed salmon in Norway
 
This fishery's resumption was sanctioned by the EU Fisheries' Minister after ICES advice ( International Council for Exploitation of the Sea ) - they had previously advised a continued moratorium but had a change of mind in spring 2017. The EU is supposed to adopt a precautionary approach in setting TAC's. They reject formal approaches that they are not doing so - relying upon ICES advice that it is safe to resume the NE sandeel fishery. 
 
I estimate it will take the rest of this year, and all of next to obtain, sufficient scales to prove statistical confidence in the research. However, since the NOCSU ) is a DEFRA approved body, it may be possible to just re-analyse the scales used in the LNSP. But these are all scales from marine-caught ST's.
 
What I would like is as many river-run ST scale-samples as is possible to target our rivers from Tweed to Tees, along with a few details of your catch: river section, weight, fork length and so on. 
 
If anyone is prepared to help, then please contact me by e-mail on dave@wks.me.uk or call 07802 264263 and I will send out a help-sheet, enveloped and tweezers . The latter could be restricted to scale us please !!
 
Obviously it is vital not to remove scales from any ST you are releasing nor to remove any scales. ST scales can be difficult to read but the results of all useable scale-readings will be coded for your privacy.
 
I am happy to travel a far as Durham, Hexham, Alnwick areas to carry out the scales removal. "
 
The report below explains the methods used.  Many thanks Dave
 

 

Not many

About

The latest fish counts have been added and not a lot to shout about in terms of numbers running the rivers. Shortage of fish or shortage of rain it could be either but the rivers really do need some rain to start to bring in the sea trout. Only the Fenton beat has produced any migratory fish reported to date. But having said that about the rivers all our three Stillwater fisheries are fishing well.

Planning application

Withdrawn

Thanks to those members that objected to the slurry farm on the banks of the river Till. We as a club objected and have received notification that the application has now been withdrawn.
