Effects of temperature on production characteristics of red drum, Sciaenops ocellatus.

摘要

Red drum, Sciaenops ocellatus, fingerlings cultured, at Clemson University (South Carolina, USA), in recirculating systems for 56 days (dates not given) at 18, 22, 26, 30 or 34℃ in salinities of 5 and 10 p.p.t. exhibited best growth at 30.4℃ in 5p.p.t. and 31.1℃ in 10 p.p.t. Growth ranged from 7 to 125%. Survival and condition factor were not affected by temperature. The results indicate that optimization of temperature in red drum culture systems will have profound effects on productivity.
