Size and abundance of cutthroat trout in small southeast Alaska lakes, 1993

Description

Abundance and size of cutthroat trout Oncorhynchus clarki was measured in thirteen small, less than 50 hectare, Southeast Alaska lakes. Each lake was sampled for three days in 1993. Catches of cutthroat trout varied widely in the lakes even though the same gear and similar effort were expended on each lake. Lengths of cutthroat trout generally fell into one of three ranges according to the following lake types: 1) lakes which support anadromous fish, 2) landlocked lakes without kokanee, and 3) landlocked lakes which have kokanee populations present. Mark-recapture experiments were conducted to estimate abundance of cutthroat trout 180 millimeters fork length in three of the small landlocked lakes in Southeast Alaska: Buck, Little Eva, and Upper Wolf lakes. Estimated abundance at Buck Lake was = 441, = 52; estimated abundance at Little Eva was = 380, = 28; and estimated abundance at Upper Wolf was = 1233, = 113.
