Abstract

The work discussed in this report deals with aspects of the ecology of Arctic charr (Salvelinus alpinus, L.). The main aims of the study were: (1) To assess the relative abundance of migrants entering the River Liza and Smithy Beck in the English Lake District). (2) To assess the degree of stream specificity. (3) To determine the period of residency in the streams. (4) To obtain a better understanding of migratory behaviour. (5) To determine the growth rate of mature fish. (6) To determine the morphometric and meristic attributes. In conjunction with this work a study was carried out to investigate the feasibility of using a video recording system to monitor the migration of charr in Smithy Beck.
