Title: The status of the Windermere charr populations
Author: C. Mills
Document Type: Monograph
In 1986 North West Water commissioned a report "A general assessment of environmental and biological features of Windermere and their susceptibility to change" from the Freshwater Biological Association. In this report it was noted that the population of arctic charr, Salvelinus alpinus, in the lake had increased since the FBA started culling pike in 1947, but that detailed information was lacking. Concern was expressed that the charr might be sensitive to the reduced concentrations of hypolimnetic oxygen that are now occurring in the south basin of the lake. Consequently, North West Water agreed to part fund a two year study to investigate the status of the Windermere charr populations. This interim report presents results from the first year of the study and also draws on some earlier work.
