Abstract
The limnetic zooplankton in lakes of the Naknek River system in southwestern Alaska was sampled extensively during 1962-63. The numerically dominant forms of limnetic zooplankton were Diaptomus, Cyclops, Daphnia, Bosmina, coregoni, Kellicotia, and Conochilus. Some littoral and benthic forms were also identified but not studied in detail. Species composition and the relative abundance of each species differed considerably among the four major lakes and also among basins within the lakes. These differences were consistent with limnological differences in physical and chemical characteristics. Iliuk Arm contains glacial flour from glaciers and pumice from volcanic activity and had the lowest standing crop. The clear and warmer waters of the North Arm of Naknek Lake had the highest standing crop. Seasonal pulses of zooplankton occurred in mid-July and again in late-August. Annual changes were also studied and in nine out of ten comparisons, zooplankton were more abundant in 1963 than in 1962.
