Description: Abundance and indices of abundance were estimated for populations of burbot Lota lota in Hudson, Moose, and Tolsona lakes in Southcentral Alaska. Sampling occurred in May and July of 1998. Bootstrapped mean catch per unit of effort of fully recruited burbot (450 mm total length and larger) per 48-h set ranged from 2.19 (SE = ) in Tolsona Lake to 3.49 (SE = ) in Moose Lake. Estimate of catch per unit effort in Hudson Lake was biased due to sampling mortality at depths greater than 8 m from low dissolved oxygen. Abundance during 1998 of fully recruited burbot estimated with mark-recapture experiments was 893 (SE = 447) in Tolsona Lake. During 1996-1997, estimated annual survival rate for fully recruited burbot in Tolsona Lake was 72.5%. Catch per unit effort of fully recruited burbot in Moose Lake was similar to estimates from 1990-1992.
