Description: Abundance and/or indices of abundance were estimated for populations of burbot Lota lota for two lakes in the Tanana River drainage. Adult (450 millimeters total length and longer) and juvenile (300 to 449 millimeters total length) burbot were captured in baited hoop traps set in a systematic pattern across each lake sampled. Sampling occurred from June through September 1992. Mean catch-per-unit of effort of fully recruited burbot (450 millimeters total length and larger) per 48-hour set was 0.20 (SE = 0.03) in Harding Lake and 0.47 (SE = 0.07) in Fielding Lake. Abundance of fully recruited burbot estimated with multiple year mark-recapture experiments was 535 in Harding Lake (SE = 201) and 592 in Fielding Lake (SE = 95) in 1991. Annual rates of survival were 49.9% (SE = 19.1) in Harding Lake and 68.6% (SE = 10.9) in Fielding Lake.
