Occasionally this species is found in the main stem of these large rivers. They do not occur in Seward Peninsula or Norton Sound drainages. Lake trout are long lived and can reach a large size, however specimens over 10 pounds are seldom taken in this part of Alaska. Northern Pike occur in the lower Pilgrim , Kuzitrin and Koyuk river drainages of the Seward Peninsula and in the Noatak, Kobuk and Selawik river drainages of the Kotzebue area. Northern pike generally occupy low lying wetland areas and interconnected lakes and sloughs in the lower reaches of these systems, although some populations are found in lakes in the middle and upper Kobuk and Noatak drainages.
Northern pike are predators, feeding primarily on other fish.
They spawn in the spring and can live for more than 20 years. Northern pike over 20 pounds have been caught in the Northwestern Management Area, however, fish from 2 to 10 pounds are most common.
