将天然海域捕捞的黄鲷Taius tum ifrons进行驯养和强化培育,人工催产和孵化。结果表明:野生黄鲷经驯化和营养强化培育,注射LHRH-A3和LHRH-A2+DOM催产后可有规律地连续产卵。产卵一般在12:00~15:00时进行,产卵期长达45~55 d。在培育水温20~22℃、盐度28~30时,受精卵经35~37 h完成胚胎发育,孵出仔鱼,受精率为90%,孵化率为87%~89%,孵出的仔鱼活泼健壮。 Domesticated and intensive breeding, artificial hatching and incubation of Taius tum ifrons from the seabed in the natural sea. The results showed that wild yellow snapper could be spawned regularly and nutritionally, and spawn regularly and continuously after injection of LHRH-A3 and LHRH-A2 + DOM. Spawning is generally carried out at 12:00 to 15:00, the spawning period as long as 45 ~ 55 d. The fertilized eggs were incubated at 20-22 ℃ and salinity 28-30 for 35-37 h. The larvae hatched larvae with the fertilization rate of 90% and the hatching rate of 87% -89%. The hatched larvae were lively robust.
