Food habits of young anadromous alewives, Alosa pseudoharengus, in Lake Ainslie, Nova Scotia.

Abstract

Until August, the larvae fed primarily on the dominant zooplankters Bosmina spp., Daphnia retrocurva and Diaptomus minutus. In August, however, the young alewives switched to feeding on adult Diptera and Ephemenoptera when zooplankton abundance was low. A substantial drop in average gut biomass was noted at this time.-from Authors
