Minard RE, Alexandersdottir M, Sonnichsen S. 1992. Estimation of abundance, seasonal distribution, and size and age composition of rainbow trout in the Kvichak River, Alaska, 1986 to 1991. Fishery Data Series. 92-51. Alaska Department of Fish and Game. Division of Sport Fish. Anchorage, AK
A total of 8,317 rainbow trout was captured and sampled at four locations in the Iliamna drainage from 1986 to 1991. Abundance estimates of spawning trout found in the Kvichak River, at the outlet of Lake Iliamna near the village of Igiugig, were derived using the Jolly-Sepber estimator and ranged from 2,038 to 4.460 rainbow trout. Estimates of survival ranged from 28% to 30%. Spawning rainbow trout tagged in the Kvichak River were primarily found at the lake outlet during the fall and to a lesser extent, at Lower Talarik Creek. Ages of spawning rainbow trout in the Kvichak River were primarily 5 (19%), 6 (21%), and 7(20%).
