ARTIFICIAL HATCHING AND PRO-LARVA DEVELOPMENT OF BANDED GROUPER EPINEPHELUS AWOARA |
|
Abstract: |
Environment factors and morphological characters are destribed for artificial hatching and pro-larva development of Banded grouper. The works Were carried out in 1981-1982. Fish with gonads in an advanced stage of maturation were selected. Fertilization of eggs were obtained by artificial insemination and fertilized eggs were hatched in hatching pots and net pots.Four hatching experiments were carried out in six groups in 1981 with a net hatch of 135,000 larvas. Ten hatching experiments were carried out in 25 groups in 1982 with result of 457,000 hatched larvas. Some of the hatched larvas were cultured in still water, others in running water. The longest survival time was 15 days. |
