Abundance and length composition of northern pike near the confluence of the Pilgrim and Kuzitrin rivers, 1992-1993

This report summarizes three sampling events conducted during 1992 and 1993 for estimation of abundance of northern pike Esox lucius in the Pilgrim and Kuzitrin rivers, Seward Peninsula. There were an estimated 10,828 (SE = 2,019) northern pike (> 300 millimeters in fork length) in 1992 in the study area, which comprised the confluence of the Pilgrim and Kuzitrin rivers. No trophy size northern pike were captured. Those northern pike that were > 300 millimeters in length were comprised of the following Relative Stock Density categories: 27% were "stock", 39% were "quality", 26% were "preferred", and 7% were "memorable". Only 7% of the 151 fish caught in 1992 and recaptured in 1993 were correctly aged as one year older. Due to the error in determining ages, the age composition of northern pike sampled in the Kuzitrin/Pilgrim study area was not estimated.
