Description: Abundance and indices of abundance were estimated for populations of burbot Lota lota in Lake Louise, Hudson, and Tolsona lakes in Southcentral Alaska. Sampling occurred during May and June of 1993. Bootstrapped mean catch per unit of effort of fully recruited burbot (450 mm total length and larger) per 48-hour set ranged from 0.45 (SE = 0.03) in Lake Louise to 3.83 (SE = 0.48) in Tolsona Lake. Abundance during 1992 of fully recruited burbot estimated with mark-recapture experiments was 4,598 (SE = 709) in Lake Louise and 1,579 (SE = 712) in Tolsona Lake. During 1991-1992, annual survival rate for fully recruited burbot in Lake Louise was 72.6%. Abundance of fully recruited burbot in Hudson Lake, estimated by direct expansion using CPUE and spring catchability coefficient, had increased from levels at the closure of the sport fishery.
