Abstract
In experiments designed to demonstrate the effects of instantaneous changes in salinity, juveniles were able to resist abrupt changes from fresh water up to 15‰ salinity without mortality, and the median lethal salinity (MLS) was 24‰. In a growth trial of 12 weeks duration at salinities of 0, 5, 10, 20, 30 and 35‰, final body weight, weight gain, specific growth rate, food intake and food conversion ratios were always higher in saline environments than in fresh water although differences were not significant. The best growth was observed at 10 and 20‰, the optimum probably being between these concentrations. The fish is clearly euryhaline.
