Hybridization is the most widely used and effective method of artificial breeding in aquaculture. To develop grouper species that were fast growing and tolerant of low temperatures, we conducted hybridization between (♂) by artificial methods. We documented embryonic development and the growth and morphological characteristics of larva, juveniles, and young fish in the hybrid was divided into cleavage stage, blastula stage, gastrula stage, neurula stage, and organogenesis stage. In sea-water (minembryonic development. The 2-cell stage occurred 1 h post fertilization (pf); the 16-cell stage at 2 h 25 min pf; the multi-cell stage at 3 h 50 min pf; the high blastula stage at 5 h 10 min pf; the middle gastrula stage at 12 h 40 min pf; the embryo body stage at 16 h pf; the closure of blastopore stage at 17 h 50 min pf; the muscle burl stage at 20 h 50 min pf; the brain vesicle stage at 24 h 50 min pf; the crystal stage at 31 h 05 min pf; the heart-beating stage at 32 h 40 min pf; the hatching stage at 35 h 10 min pf; and the newly hatched larvae stage at 35 h 20 min. There was no obvious difference in embryonic development between crossbreed F1 by except the time of the heart-beating stage. Based on the features of the yolk sac, second dorsal fin spine, pelvic fin spine, scales, and body color, the post-embryonic development of the hybrid was divided into larval, juvenile, and young fish stages. The larvae relied on their yolk for nourishment up to 4 d after hatching, at which time the mouth opened. Metamorphosis was completed ~42 d after hatching at which time the fish were classified as juveniles. The juvenile stage lasted for ~58 d, after which the juveniles became young fish. Our results suggest that the hybrid F1 grows more rapidly than either parent species.
