中国水产科学研究院长江水产研究所与湖北省水产科学研究所、英山县地热实验站合作进行罗非鱼性别控制研究,经过9年的共同努力,获得了成功,并已通过技术鉴定。参加鉴定的专家和学者们认为:此项性别控制新技术在国内处于领先地位,获得的莫桑比克超雄鱼,其形态、生长发育和繁殖机能,表现正常,成活率较高;杂交全雄鱼则具有双重优势。罗非鱼具有食性广、生长快、产量高等优良性状,但性周期短、繁殖力强任其自由繁殖,就会导致养鱼池中密度过大,影响商品鱼质量。应用雄性激素处理性腺尚未分化的罗非鱼鱼苗,能获得90％以上的雄鱼,但是,这种方法的用药量比较大,未能在生产中推广。
The Yangtze River Fisheries Research Institute of Chinese Academy of Fishery Sciences and the Hubei Provincial Institute of Fisheries, Yingshan Geothermal Experimental Station for tilapia gender control research cooperation, after nine years of joint efforts, has been successful and has passed technical appraisal. Experts and scholars attending the assessment said that this new gender-controlled technology is leading in the country and the morphological, growth and reproductive functions of the newly acquired Mozambican super-males are normal and have a high survival rate. Hybrid males Has a double advantage. Tilapia has wide feeding, fast growth, high yield and other fine traits, but the sexual cycle is short, fertility and its free propagation, it will lead to fish pond density is too large, affecting the quality of commercial fish. Application of male hormones treatment of glandular undifferentiated tilapia fry, can get more than 90% of male fish, however, this method of medication is relatively large, not in the promotion of production.
