- The aim of this experimentwas to knowthe gonad developmentof humpbackgrouper Cromileptes altivelis F-2 progeny. The F-2 progeny fishes were produced from selective breeding and composed by Lot 1, Lot 2 and Lot 3. The fishes were reared in the cylinder concrete tanks containing 75 m3, 10 m3water and floating cages. Fishes were fed with commercial dry pellet in addition with vitamin mix, vitamin C and vitamin E. The result indicated that the mature gonad female of F-2 grouper broodstocks have been achieved. The female broodstocks with 590 9 weight produced oocytes wi1hdiameter more than 400 !-1m. Genetic analysis showed that grouper Lot 2 was homogenous, no polymorphism among individual fish, however Lot 1 and Lot 3 showed high heterozygocity as 0.18 and 0.58, respectively.
