摘　　要：以鱼粉、豆粕、棉粕、菜粕为蛋白源,以豆油为脂肪源配制基础饲料,按1%、2%、3%的剂量添加蜂花粉至基础饲料中制成3种试验组饲料,在室外池塘中对黄尾鲴开展为期8周的摄食生长试验。结果表明:2%和3%蜂花粉组亲鱼性成熟比例显著高于对照组和1%蜂花粉组(P<0.05),其亲鱼性成熟比例为85%以上,而对照组为65%;从卵子质量来看,对照组黄尾鲴亲鱼卵径、受精率、孵化率以及出膜仔鱼全长显著低于添加蜂花粉组(P<0.05);从精子质量看,亲鱼日粮中添加高比例的蜂花粉能显著提高雄性亲鱼的繁殖性能(P<0.05),与对照组相比,2%蜂花粉组可提高精子密度45.3%,提高精子活力12.7%,精子畸形率下降21.0%。综合考虑,2%蜂花粉为黄尾鲴亲鱼最佳添加量。Feeding growth test of Xenocypris davidi Bleeker was carried out in outdoor ponds for 8 weeks; three experimental group feeds were made by adding bee pollen to the basic feed at the dosage of 1%, 2% and 3%, with fsh meal, soybean meal, cotton meal and vegetable meal as protein source, and soybean oil as fat source for basic feed. The results showed that： the sexual maturation rate of the parent fsh in the bee pollen group with the addition of 2% and 3% was signifcantly higher than that in the control group and the bee pollen group with the addition of 1% （P〈0.05）. From the perspective of egg quality, the egg diameter, fertilization rate, hatching rate and the length of membrane larvae in the control group were signifcantly lower than that in the bee pollen group （P〈0.05）. From the perspective of sperm quality, the addition of high proportion of bee pollen in the diet of parental fish can significantly improve the reproductive performance of male parental fsh （P〈0.05）. Compared with the control group, the addition of 2% bee pollen increased sperm density by 45.3%, sperm motility by 12.7% and the rate of sperm malformation by 21.0%. All things considered, the best amount of yellowtail catfsh was 2% bee pollen.
