Abstract
Pompano (Trachinotus blochii) nurseing applying different salinities in recirculating system was conducted in the College of Aquaculture and Fisheries, Can Tho University from May to June 2019. The experiment included three treatments with different salinities: 10; 20; 30‰ was used with four replications. Pompanos (0,7 g/fish) were reared in 500L tanks at 60 fish/m3 and were continuously aerated. The experimental fish were daily fed with commercial pellets (44% protein) at rate of 15% total body weight and adjusted for demand in all treatments. After thirty days of rearing, the growth rate of treatment 10‰ (0,18 g/day and 7,24 %/day) and the treatment 20‰ (0,18 g/day and 7,20 %/day) were significant higher than the growth rate of treatment 30‰ (0,15 g/day and 6,75 %/day). However, the highest survival rate was found in the treatment 10‰ (99,2%). Rearing pompano in the recirculating system gave the best results at stocking salinity 10‰.
