Ongoing Projects
 
Hampshire Avon Salmon Habitat Improvement Project
 
Hampshire Avon salmon stocks are at a low ebb, this project has assessed spawning and juvenile habitat quality, produced recommendations for improvements (primarily increased boulder/flint cover for fry & parr) and implemented those improvements. A first phase of monitoring has been completed. This rapid response has been made possible by effective liaison and co-working with Environment Agency and Natural England staff and Riparian Owners.
 
Location: River Nadder - Hurdcott middle Br, Wilton House sawmill Br, Burcombe u/s Mill House, Barford St Martin d/s road Br.                 
River Wylye - Wilton House sidestream, Wilton House u/s Image Br, South Newton footbridge, Langford Lakes, Wylye Flyfishers cottage beat.
 
Timing: May/June 2013, Monitoring (electric fishing surveys) 2013, 2014 & onwards. Possible Phase II of project 2014.
 
Partners: WCSRT, Environment Agency Blandford Office, Riparian Owners & Fishing Clubs.
 
Budget: Greensand donated by Hurdcott Estate, flints purchased by EA, Implementation EA/WCSRT staff. Total costs (excluding staff time) less than £1,000.

Preliminary findings: River Wylye monitoring survey showed ~ 5 times as many salmon parr in improved area than in control stretch.
 
Hurdcott monitoring survey showed moderate salmon / trout parr densities where habitat improved and none on control section.

The Future: Our intention is to extend this successful pilot project, hopefully with EA funding, to further survey the Hampshire Avon Catchment salmon spawning sites and develop and implement improvement projects for each one.

 
River Catchment Invertebrate Fingerprinting study and GIS mapping programme
 
Proposal for benthic invertebrate community analysis & mapping exercise to pinpoint pollution inputs and habitat degradation on catchments of Rivers Avon, Stour, Test, Itchen & Meon. The objective is to use this mapping to identify and tackle the pollution sources across the catchments. Grant funding was received in Spring 2014.
 
Partners: WCSRT, Aquascience Ltd
 
Timing: 2014 -2018         
 
Outcome: As of September 2014, 35 years of EA invertebrate kick-sampling data for the Hampshire Avon, Test and Itchen catchments have been analysed by Dr. Nick Everall of Aquascience Ltd. The results of this analysis can be found here. T
his historic EA data are comprised of family level information. We are currently collecting fifty new kick-samples across the three catchments which will be analysed at species level this winter, this will make it possible to detect a much wider range of pollutants eg. heavy metals.

Lower Hampshire Avon Cormorant Diet Project.
 
Cormorant numbers have increased markedly in recent decades and widespread concerns have been expressed over potential impacts on fish stocks, including species of conservation concern such as Atlantic salmon and upon fisheries in general. This study includes three sites on the Avon between Salisbury and Christchurch Harbour where cormorants roost and where samples of regurgitated food remains are being collected regularly and identified to produce objective data on cormorant diet.
 
Location: 2013 - Avon Tyrell Estate.
 
Timing: Initial feasibility study spring 2013 (starting while salmon smolt run is occurring), due to continue 2014.
 
Partners: WCSRT, Riparian Owners, Bournemouth University, Environment Agency (Blandford Office).
 
Budget: Zero in 2013, except for staff time. Likely funding bid 2014.


Preliminary findings: 2013 Monthly pellet samples collected, under analysis by Prof Rob Britton Bournemouth University. As expected, a mix of inshore marine and freshwater fish species: Wrasse, Mullet, Perch, Cyprinids recovered so far.

The Future: We are currently seeking other suitable roost study sites in the upper Avon catchment to extend our knowledge of cormorant predation on wild fish stocks.

Professor Britton and Pete Reading, WCSRT Education Officer, have been conducting a parallel pilot study of Otter diet on the Avon and have found a wide range of fish species being eaten from Bullheads to Barbel. As soon as the results of both these studies are finished they will be made available on the WCSRT website.

Sediment-Free Salmon Project
 
Brief description: Salmon are handicapped by poor egg-incubation conditions in our local rivers resulting in high early losses (90-100% dying, as reported by Portsmouth University/Cefas). WCSRT/Trafalgar Fisheries kept eggs free of fine sediment on a daily basis. Outcome: 75-95% surviving to the ‘swim-up fry’ stage showing interception of sediment run-off to our rivers can deliver large dividends.
 
Location: fertilised eggs were obtained from 3 pairs of salmon (Nadder and lower Avon). Eggs incubated by Trafalgar Fisheries, using trays supplied with a blend of settled river water and groundwater.
 
Timing: January-May 2011.
 
Partners: WCSRT, Trafalgar Fisheries, fishing clubs, landowners, keepers and Mudeford netsmen. (Consents from Environment Agency & Natural England).
 
Budget: c.£700, plus unpaid staff time provided by Trafalgar Fisheries.
