Abstract
Two-day-old larvae of striped bass (Morone saxatilis) were trained to accept artificial feed. When the fish reached 10 g, 1080 were stocked in a 0.4-ha hatchery pond. The fish were stocked on 7 August 1976 and harvested 441 days later on 19 October 1977. They were fed daily through the fall of 1976 and again during the spring, summer, and fall of 1977. The fish stopped feeding in the fall when the water temperature fell to 7°C, and resumed feeding in the spring when the temperature reached 16°C. Once they began to feed, they fed well when the temperature was above 10°C, but poorly when the temperature was 29°C or higher. The fish were fed 291 of the 441 days during which they were held in the pond. The rate of growth was 2.03 g per fish per day; 980 kg/ha of striped bass were produced. Food conversion was 2.8 for the 85% of the population that ate the artificial feed. Survival was 91.8%.
