Abstract
本发明涉及水产养殖技术领域，尤其涉及一种耐低氧金鲳的育种方法。包括：选取健康、发育良好的雄性亲本和雌性亲本，将亲本放于暂养池，所述暂养池持续增氧；构建鱼类高 / 低氧自动控制系统，并进行蓄水、杀菌，控制溶氧量；在系统开启一天后引入亲本，亲本在转运前禁食12h，适应1～2天后开始间歇低氧训练5周；对亲本进行催产及受精卵孵化：在间歇低氧训练结束后第二天进行催产；催产后在孵化桶中进行鱼卵孵化，及时挑出坏死卵，孵化期间溶解氧维持在6～7mg / L；通过鱼卵孵出鱼苗，至鱼苗15～35日龄后投喂人工配合饲料，保持水温不低于26℃。优点在于：金鲳子代携氧能力及低氧耐受能力有明显的改善，具有很好的低氧适应性。
