Abstract Survival and growth of 0.3–0.9 g red drum Sciaenops ocellatus were measured for fish reared in water‐recirculating culture systems containing one of the following media: 6g/L diluted seawater; 1g/L diluted seawater; 1g/L diluted seawater with either 1 or 5g/L of additional salt. Salt was added as sodium chloride, calcium chloride, or magnesium sulfate. Mean survival over the 42‐d study period was 56.3%. The 5g/L sodium chloride treatment had the highest survival rate (80.0%) and the calcium chloride treatment had the lowest (26.7%). The biomass‐change rate for fish in the 5g/L calcium chloride treatment was significantly lower ( P < 0.05) than for fish in the 5g/L sodium chloride, 1g/L sodium chloride, or 5g/L magnesium sulfate treatments. The latter three treatments gave biomass‐change rates that did not differ ( P > 0.05) from those obtained in the 1 or 6g/L diluted seawater.
