The diamond turbot (Hypsopsetta guttulata) population from Anaheim Bay, California was analyzed by a model that describes feeding rates in a cyclical diel feeding fish and that allows the calculation of daily ration from field data. Diamond turbot over 25 g in body weight at 3.76% of their body weight per day and had an estimated gross growth efficiency based on 80% digestion of 12.0%; the population of 3,400 diamond turbot ate 3,690 kg/year, mostly clam siphons and polychaetes.
