中文摘要:

      在人工饲养条件下，模拟自然环境对野生眼斑双锯鱼Amphiprion ocellaris进行驯养使其达到性成熟、配对、产卵。显微镜下观察其胚胎发育的形态学变化。结果表明，眼斑双锯鱼的胚胎发育同大多数硬骨鱼类基本相似，属端黄卵盘状卵裂；在水温27.0±0.5℃条件下，经192~216 h完成孵化；仔鱼在孵出的第2天开食轮虫，4~5 d变态为稚鱼，开始投喂卤虫无节幼体，18~20 d进入幼鱼期，45~50 d开始投喂人工配合饵料及碎虾肉。

英文摘要:

      Amphiprion ocellaris, an ornamental fish collected from the wild, was cultured to mature and spawned in artificial condition. The embryonic development was observed under a microscope and it was found that the development was similar to most teleosts. The eggs belong to the telolecithal and are subject to discoidal cleavage. The incubation period was 192~216 hours at 27.0±0.5℃. The larval fish could be fed by rotifer in the second morning after hatching, and were developed into juvenile at 4~5 days after hatching and into parr at 18~20 days after hatching. The parrs could be fed by artificial food and shrimp meat at 45~50 days after hatching.
