本发明涉及工厂化养殖大菱鲆领域。其技术特征是向圆形的钢筋混凝土产卵池内注入深度为2－4米的海水；用遮光布将池顶遮光，遮光率达95％以上；向产卵池内放入雌、雄大菱鲆，其密度为每百立方米水体6－30尾，雌雄比为1∶2；保持产卵池内的水温在11－16℃；采用光强为600－1500lx的人工光源对产卵池进行照射，每天的光照时间为12－16小时；每天向产卵池内投喂新鲜小鱼，并定时定量换水，换水量为3－5倍。 A method for industrial raising pygmy flounder by natural spawning is characterized by that the seawater is filled in a spawning pool until water depth is 2-4 m, a light shielding cloth with 95% of optical shielding rate is installed above the spawning pool, the male and female pygmy flounder in the ratio of 2:1 are raised in the pool at 11-16 deg.C of water temp, and the spawning pool is artificially irradiated by 600-1500 lx for 12-16 hr perday.
