【摘要】 本研究对斜带石斑鱼(Epinephelus coioides)进行强化培育,实现自然产卵,以自然产出的受精卵为材料,对其胚胎发育各阶段的形态特征进行了详细的描述。结果表明:亲鱼培育的情况经过15 d左右的强化培育,斜带石斑鱼亲鱼卵巢可从Ⅲ期发育到Ⅳ期并产卵;受精卵为透明,圆形,浮性卵,卵径为0.78±0.16 mm,有油球一个,居卵中央,油球径0.17±0.04 mm,受精卵孵化共分为卵裂期、囊胚期、原肠期、器官分化期和仔鱼出膜期等阶段,在水温25-28℃,盐度30%时经过25小时45分钟,可孵化出仔鱼。

【Abstract】 Brood stock Epinephelus coioides was cultured with enriched feeds and naturals pawning in indoor ponds,and the morphological characters were described on different embryonic development phases of natural embryonated egg in detail.The study showed that the ovary of Epinephelus coioides had developed from Ⅲ stage into Ⅳ stage after about fifteen day embryonic development and ovulated;the fertilized eggs of Epinephelus coioides were spherical,transparent,floating,each egg has one oil globule,the diameter of the eggs and globule are around 0.78±0.16mm and 0.17±0.04mm respectively.Hatching of embryonated egg included cheavage stage,blastulation stage,gastrulation stage,organ differentiation stage and hatching stage.When the water temperature was 25-28℃ and salt was 30‰,hatching of larvae took 25 hours and 45 minutes.
