Growth of Atlantic salmon (Salmo salar) parr was studied at environmental salinities of 0.1, 10, and 20‰ in relation to daily rations of 0, 1.0, 1.5, 2.2, and 2.9% of dry body weight. Instantaneous growth rates and food conversion efficiencies for fish in each salinity were similar. Maintenance ration was slightly more in 20‰ than in either the salinity approximately isosmotic with blood (10%) or in fresh water (0.1%).
