Abstract
Four near-surface locations in Pyramid Lake, Nevada, were sampled for larval tui chubs (Gila bicolor) during summer and early fall 1979. Numbers of larvae collected were highest in mid-July. Zooplankton was the only food eaten throughout the survey; the cladoceran Moina hutchinsoni was the major species eaten at all locations. Another cladoceran, Diaphanosoma leuchtenbergianum, was also important to the diet of pelagic larvae, and the copepod Cyclops vernalis was eaten in significant quantities by nearshore fish. Changes in diet composition of larval tui chubs during summer corresponded to seasonal succession of zooplankton species in Pyramid Lake.
