摘要
记述了蓝鳃太阳鱼 (Lepomismacrochirus)的繁殖行为、卵子性状、有效繁殖力和培育鱼苗鱼种的结果。蓝鳃太阳鱼由雄性作巢并护巢。卵粒小 ,沉性、粘性 ,胚胎发育积温为70 0～ 80 0℃·h。生产的鱼苗全年累计每 1 0 0g体重雌鱼可获得鱼苗 640 1尾。鱼苗培育成活率 72 .2 % ,鱼种培育成活率 93.8%。
The propagation behavior, egg characters, available fecundity of the blue gill sunfish (Lepomis macrochirus), and the fry and fingerling rearing experiments were described . The male parent fish was responsible for nest building and protection. The fertilized eggs were small, demersal and adhesive. The accumulated temperature in the embryo development was 700～800 ℃·h. In total, the fry output was 6 401 produced by the female fish of average weight of 100 g in one year. The survival rate of the fry rearing and fingerling rearing were 72.2% and 93.8% respectively.
