罗非鱼是占世界性养殖鱼类之一。由于罗非鱼成熟早,繁殖周期短,往往因繁殖过度导致种群过剩,个体小型化,影响了鱼产量,降低了商品质量。为此,我们在1985年利用人工控制性别技术,进行了罗非鱼种间杂交,生产全雄子代并养成商品鱼,提高了单位面积产量和商品鱼规格。本文主要介绍全雄性苗种生产技术及养殖成商品鱼的试验经过和结果。 Tilapia is one of the world’s farmed fish. Because tilapia mature early, reproductive cycle is short, often due to overpopulation lead to overpopulation, individual miniaturization, affecting the fish production, reducing the quality of goods. To this end, we made use of artificially controlled gender techniques in 1985 to carry out interspecific hybridization of tilapia to produce whole male offspring and develop commercial fish, raising the yield per unit area and the size of commercial fish. This article describes the whole male seed production technology and aquaculture into commercial fish test results and results.
