Description: Populations of northern pike Esox lucius in Volkmar, T, East Twin, and Harding lakes in interior Alaska were studied during spawning in the spring of 1993. Multiple capture- recapture events were used to estimate the abundance of northern pike > 299 millimeters fork length. Abundance was estimated to have been 4,160 northern pike in Volkmar Lake in 1993 (SE = 605; 15.2 per hectare). The abundance of northern pike in T Lake in 1993 was estimated to have been 853 fish (SE = 137; 5.4 fish per hectare). The estimated abundance of northern pike in East Twin Lake was 6,070 fish (SE = 757; 11.5 fish per hectare). Abundance of northern pike in Harding Lake in 1993 was estimated at 9,309 fish (SE = 750; 5.1 fish per hectare). Populations of northern pike in Volkmar, East Twin, and Harding lakes were composed primarily of the Relative Stock Density category of stock-sized fish (300-524 millimeters), while quality-sized fish (525-654 millimeters) predominated in the population in T Lake. Age 5 northern pike were most abundant in all lakes except Harding Lake, where age 4 fish were dominant. Data collected since the inception of northern pike research in Volkmar, T, East Twin, and Harding lakes are summarized.
