Artificial Breeding of Rachycentron canadum
摘要
Abstract
Artificial breeding and larva-rearing of Rachycentron canadum were conducted indoors and outdoors, respectively, in Guangxi Institute of Oceanology. The parent fish were selected in Hainan and Fujian. After a period of breeding, the parent fish were injected hormone and produced sperms and egg cells, then egg cells inseminated naturally. The zygotes were hatched indoors by three means,including cage with running water, black bucket with full air and nursery pond with full air, on the contrary outdoors by cage in tank. When the larvae began to eat, they were let out from the cage, bred with good fit bait and harvest after 30 days. In results, we obtained 1. 585 X 106 zygotes of high quality, 1. 488 X 106 larvae and the hatching rate reached 93. 8%. Meanwhile, the cage with running water proved better among three means indoors. The average survival rates of the fry were 12. 61% indoors and 7. 52% outdoors, thus ~ the survival rate indoors was 5. 08% higher than that outdoors.关键词
