Abstract
The experiment of the effect of temperatureeffecton embryonic development and malformation of pompano (Trachinotus blochii) was carried out at the Northen National Broodstock Center for Marine aquaculture oin Cat Ba, Hai Phong, Vietnam. Five temperature levels of 24oC, 26oC, 28oC, 30oC and 32oC were studied with 3 replicates each. The results showed that,there was a significant differencetbetween five treatments in terms of hatching, deformity and survival rates. The result indicated that the significant highest hatching rate was 47.7% at 24oC. The lowest deformity rate was observed at 24oC (3.3%) but no significant difference was found between 24oC, 26oC and 28oC. The survival rate was higher at 26oC (58,6%) and 28oC (58,2%) after five days of post-hatching than other. The results show that sSuitable temperatures for pompano incubation are ranged from 24oC to 28oC. At 26oC and 28oC, the lowest deformity rate (3,98 - 4,20%) and the highest survival rate (10.48% and 10.69%) after 40 days of post hatching were recorded. From this study, the temperature rangedfrom 26 - 28oC are recommended for pompano rearing.
