Abstract

• Artificial propagation of fish is an alternative to meet increasing demand for food fish. Seabass (Lates calcarifer) is one of the commercially important species in Myanmar. It is fast growing and euryhaline. This fact is seen as a valuable attribute for species enabling its adoption for ponds and cages culture under marine and brackish water environment. This study was conducted to assess the breeder management for artificial propagation of seabass. The study period was from September 2017 to December 2018 in Myeik Archipelago. The breeders were reared for two months before injection to be healthy fish. The male and female spawners were selected and injected hormone which was calculated to males and females, and their body weight. Induced breeding of study species was studied and number of fertilized eggs, per cent of mortality rate and survival rate were observed seasonally. The hatching rate and survival rate of study fish were highest in hot season. Larvae rearing and different diets on larvae were observed. The effects of weather and water parameters of the study area were collected.
