一、人工繁殖技术 (一)做好亲鱼的选择工作:选择2冬龄达到性成熟的黄尾密鲴,体重在350～450克,于每年捕捞季节在江河、水库、湖泊等大水面内捕获繁殖备用亲鱼。其雌雄鉴别是:雄鱼头部、鳃盖、尾柄、胸鳍等处“追星”较多,抚摸粗糙,轻压腹部有乳白精液流出,个体较小;雌鱼腹部突出,卵巢明显而柔软,无“追星”出现。 (二)如何培育捕获的亲鱼:对亲鱼采取强化培育方法,以高等植物枝叶、硅藻和丝状藻为主食,也食少量的甲壳动物和水生昆虫。单养放养密度每亩300尾左右。混养90～100尾 First, the artificial breeding technology (A) do a good job in the selection of broodstock: Select 2 winter age to reach sexual maturity of the yellow tail wax, weighing 350 to 450 grams, in the annual fishing season in rivers, reservoirs, lakes and other large surface capture Breeding spare broodstock. Male and female identification is: male head, gill cover, caudal peduncle, pectoral fins, etc. “chasing stars ” more, stroking the rough, soft pressure out of the Ministry of the milky white semen outflow, individual smaller; female abdomen prominent ovarian obvious Soft, no “chasing stars ” appear. (B) how to cultivate the captured broodstock: adopt intensive breeding of broodstock to higher plants foliage, diatoms and filamentous algae as the staple food, but also eat a small amount of crustaceans and aquatic insects. Single stocking density of about 300 per acre. Polyculture 90 ~ 100 tail
