甲鱼(俗称鳖)在市场上雄性鱼比雌性鱼销路好,售价也高,一般每公斤雄甲鱼300元左右,是雌甲鱼价的两倍左右。价高的原因是因雄甲鱼的滋补、营养价值高。人工养殖情况下,雄甲鱼生长快于雌甲鱼,而且在抗病力、成活率、料肉比方面都优于雌甲鱼。因此,专门培育全雄性甲鱼养殖,成为科技工作者关注的问题。 Turtle (commonly known as turtle) in the market male fish than female fish sell well, the price is high, generally about 300 yuan per kilogram of male turtle, is twice the price of female turtle. The reason for the high price is due to tilapia nourishing, high nutritional value. In the case of artificial breeding, the beetle grew faster than the female turtle, and was better than the female turtle in terms of disease resistance, survival rate and feed conversion ratio. Therefore, to cultivate all-male turtle breeding has become a concern for scientists and technologists.
