Summary

Life histories of Daphnia galeata mendotae, D. retrocurva, D. parvula, D. ambigua, and D. schoedleri are compared with year class strength and food of threadfin shad in Bull Shoals Reservoir from 1965 to 1967. Maximum population density of daphnids was in April, May, and June. Populations declined to insignificant densities throughout the rest of the year. Declines coincided with the inclusion of Daphnia in the diets of threadfin shad smaller than 14 mm. Declines in the summer of 1967 coincided with both young shad predation and high Leptodora kindtii density. Population changes associated with declining year class strength of threadfin shad were an increase of the large D. schoedleri and Leptodora kindtii from nondetectable or trace densities to relatively large populations, and increase from nondetectable densities of daphnids in the summer to detectable densities, and a twofold to threefold increase in the summer standing crops of Bosmina longirostris.
