Summary: | 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. |
