Long term temperature monitoring of Salmon (Salmo salar) spawning streams in
the (Welsh) Wye river catchment
—————————————————————————————————-
Project summary
Overall aim of the project is to monitor water temperatures in key spawning
streams over a period of years in order to gain a better understanding of the effect of ambient stream water temperatures on the spawning success and survival of salmon parr and other economically important salmonids.
Temperature data recorders will be used to gather stream water and local air temperatures. In stream temperature data will be correlated with ambient air temperature, fry and parr numbers, supplied from annual NRW published electro fishing data, and other relevant
environmental and biological data. The results will used to help NRW/EA develop an effective management plan for salmon and assist in assessing the impact of higher average temperatures (global warming) on the spawning success of salmon and brown trout (Salmo trutta). Effective management. of the stock of these economically important salmonids, could contribute significantly towards the maintenance of the ‘tourist £’ spent on fishing for trout and salmon within the Wye catchment areas of England and Wales.
This project will be undertaken by Wye Salmon Association (WSA) in partnership with
National Resources Wales (NRW) and when required, the Environment Agency (EA). WSA will be responsible for managing, collecting and analysing the temperature data and NRW/EA for providing technical and other assistance. Help and support will also be sort from the Universities of Nottingham and Loughborough through our association with The Loughborough University Temperature Network (LUTEN).
