Abstract
Southern flounder ( Paralichthys lethostigma) were spawned during March, 1997, and 4-day post hatch larvae (mean TL=2.0±0.1 mm) were stocked into two 0.1 ha ponds at a density of 74 m −2. At stocking, water temperature was 20°C and salinity 30 ppt. No supplemental feed provided and fish were harvested after 74 days of culture (June 9). A total of 5587 fingerlings were harvested from the ponds and average survival was 3.8%. Mean fish length in one pond was 37±7 mm (23–54 mm) while mean size of fish in the other pond was 55±8 mm (38–80 mm). Incidence of pseudoalbinism was extremely low (<1%) in both ponds. The 78-day old fish which were harvested from the ponds were converted to dry diets in 14 days. Average survival during the transition period was 80.4%. In contrast, fish harvested, during a previous pond nursery study, at an age of 220 days required 106 days to transition to dry feeds. Survival during transition averaging 58.2%.
