Some observations on autumn‐spawning charr, Salvelinus alpinus L., in Windermere, 1939–1982
Every year from 1939 to 1982 autumn‐spawning charr, Salvelinus alpinus L., have been monitored in the north basin of Lake Windermere. Gillnets of mesh 32 mm bar were used. Up to 1974 the nets were set in Low Wray Bay, but, because of interference by the public, from 1975 they have been set at Thomps...
