Abstract An experiment was conducted to investigate the effect of dietary Enteromorpha prolifera in dif‐ferent formulations (different protein ,fat and other essential nutrient contents) on growth performance of turbot Scophthalmus maximus (150 .1 ± 21 .7) g based on feeding rate method .The turbot were cultured with natural seawater mixed with deep well seawater in cylindrical water ponds with diameter of 100 cm and height of 110 cm .A total of 900 individuals of turbot were randomly divided into 15 groups with three replicates ,20 individuals in each pond for 35 d .The results showed that in the range of experiment de‐sign ,commercial feed B group and commercial feed A group ,containing higher content of protein and ash there were significant better grow th performance than in self‐made feed group .Addition of the green alga at a dose of 5% into three different feeds helped to increase the feeding rate and weight gain rate of self‐made feed group , reduced the feed coefficient of commercial feeds A and B and increased the specific grow th rate of all three groups ,indicating that 5% addition of green alga led to good grow th in turbot .
