Dietary Studies with American Shad Fry

Abstract
Studies were conducted to evaluate foods for fry of American shad (Alosa sapidissima) in earthen ponds and outdoor tanks. Fry grew rapidly (more than 100 mg in 4 weeks) in both ponds and tanks when suitable food was available. Live Daphnia magna and D. pulex were excellent food sources. A commercial fry feed for trout and a mixed culture of rotifers and wild Moina sp. also produced acceptable growth. Despite the fact that a considerable amount of phytoplankton was found in the stomach contents, phytoplankton alone did not appear to be a suitable diet for shad fry.
