Download the data

This dataset consists of information regarding the abundance of fish species from Windermere, and includes long-term data on Arctic Charr (Salvelinus alpinus), Pike (Esox lucius), Perch (Perca fluviatilis) and some recent data on Roach (Rutilus rutilus) from net and trap sampling, together with data on total fish abundance from hydroacoustics. Data collection began in 1940. With the exception of the hydroacoustics, the data were initially collected by the Freshwater Biological Association (FBA) but have been collected by CEH and its predecessor Institute of Freshwater Ecology (IFE) since 1989. The hydroacoustics data have been collected by CEH/IFE since 1990. The data available to download originate from Windermere North and South Basins and are given as yearly averages.
