Abstract

Pyramid Lake fish populations were sampled with nets on a monthly basis from November 1975 through December 1977. Fish species were taken in the following order of numerical relative abundance: tui chub (Gila bicolor), Tahoe sucker (Catostomus tahoensis), Lahontan cutthroat trout (Salmo clarki henshawi) including cutthroat-rainbow hybrids, cui-ui (Chasmistes cujus), and Sacramento perch (Archoplites interruptus). Relative abundance estimates are discussed with respect to seasonal availability, spatial distribution of the fish, sampling bias of the fishing methods, and biomass of the fish. Recent temporal trends in the population structure of the lake are presented.
