Abstract:
Early
development of the F1 hybrid between the goldblotch grouper, Epinephelus
costae female and dusky grouper, E. marginatus male was compared
to that of the maternal species under similar rearing conditions. Percent
fertilisation and percent hatch were not significantly different. Mean
hatching time of the hybrid was significantly faster than the goldblotch
grouper. Percent of deformed blastomeres in the 4-8 cell stage was
significantly higher in hybrid eggs. Survival of eggs, larvae, and larval
growth and the behavior of both types were not significantly different.
Results suggest that this hybrid may be suitable for aquaculture purposes.
