本项目实施后,共收集、引进石斑鱼亲鱼228尾,其中:2001年下半年,在本地收集、驯养石斑鱼亲鱼36尾,体重1.0-1.6公斤,2002年10月从上海铜川路购进规格为1.0-1.5公斤/尾石斑鱼亲鱼192尾。2003年4月和2003年5月分别进行两次人工催产,注射鱼用催产激素LRHA-2,人工挤出少量卵,但由于没有雄鱼,未获得受精卵。2002年6月2日从福建引进石斑鱼受精卵1.5公斤,计180万粒,受精卵平均孵化率78%,人工培育出开口10天仔鱼124.1万尾,仔鱼开口后7天成活率88%,2002年6月12日通过了江苏省海洋研究所组织的阶段性现场验收,仔鱼经人工培育,于2002年7月15日出池,共培育规格为3.2cm石斑鱼鱼苗5.6万尾,从初孵仔鱼至鱼苗成活率4%。通过本项目的实施,引进石斑鱼受精卵,进行人工育苗,为我省海水鱼养殖提供了新的思路。
