Description: Estimated abundance of northern pike Esox lucius > 450 millimeters near the confluence of the Pilgrim and Kuzitrin rivers was 9,998 fish (SE = 2,307). For northern pike > 450 millimeters, 40% were "quality" size, 30% were "preferred" size, 21% were "stock" size, and 8% were "memorable" size in Relative Stock Density categories. The age 7 cohort was the most abundant. The oldest fish sampled was age 22. Since northern pike moved between the two rivers, the Pilgrim River cannot be considered as closed to immigration or emigration.
