Abstract
This study is aimed to estimate the reproductive performance of domesticated female black tiger shrimp in the fourth generation G4 indoor- rearing which is produced from the project “Study of bio-technological application to select black tiger shrimp (Penaeus monodon) broodstock with fast growth characteristic”. The maturation ratio of the shrimp G4 was 100%. At the 1st spawning, the spawner was 73,3±6,6g in average body weight, 50% in spawning ratio, 283.556±75.801eggs each spawner in the practical reproduction, 84,9% ±7,5% in fertilized ratio and 96,3% ±3,4% in hatched ratio; At the 2nd spawning the data were: 78±2,5 g, 75,9%, 265.600±97.240 eggs per spawner, 91,8%±3,4% and 92,1%±4,4% respectively; and at the 3rd spawning the data were 75±7,5 g, 18,2%, 204.444±34.667 eggs per spawner, 72,4%±16,2% and 60,5%±45,4%. The results indicated that the practical reproduction, fertilized ratio and hatched ratio of the shrimp at the 3rd spawning significantly declined (p
