本文报道了采用胸鳍基部一次注射LRHA-A2和DOM催产花亲鱼,采用平铺、悬挂、底层漂浮棕榈皮鱼巢三种接卵方式及流水条件下遮光、不遮光,静水条件下遮光、不遮光四种不同孵化方式的试验结果。在水温18.2~19.8℃条件下,花胚胎发育需140 h破膜。观察了胚后组织、器官、系统生理发育过程,该鱼在破膜后52h进入混合营养期。不可逆点(PNR)为仔鱼破膜后第8d。 In this paper, we report the three kinds of oviposition methods of floating, tying, hanging, and bottom floating palm-lined fish nests with one injection of LRHA-A2 and DOM at the base of the pectoral fin. They were shaded under no-shading conditions, Four different hatching test results. In water temperature 18.2 ~ 19.8 ℃ conditions, embryonic development 140 days need to break the membrane. After the embryo tissue, organ and systemic physiological development were observed, the fish entered the mixed nutrition period 52h after rupture of membranes. The irreversible point (PNR) after larval rupture of the first 8d.
