DAPHNIA MAGNA CULTURE ON HIGH-RATE OXIDATION POND EFFLUENT

ABSTRACT

Daphnia magna was cultured continuously on effluent of high-rate oxidation ponds as an alternative method of harvesting bacterial and algal biomass while producing high—value animal protein that could be used for fish and crustacean larval feed. Average production is 30 mg dry weight daphnia per liter per day. This high production potential, on a readily available and cheap source of nutrients, raises the possibility of developing a reliable, cheap source of larval foods to answer aquaculturists' needs.
