摘要：
淇河鲫(Carassius auratus in Qihe river)是河南省特有的名贵优质鱼类,其体型丰满、体色鲜亮、营养丰富.淇河鲫的繁殖方式为天然雌核发育,故多为三倍体.本研究选取14条健康的成熟淇河鲫雌鱼,取卵子混合后,分别用淇河鲫、荷包红鲤、红鲫、黄河鲤的成熟精子刺激并采用干法授精的方式进行人工授精.孵化后培育,分别在5月龄及7月龄时测量4种精子刺激的淇河鲫子代的体长、体高、体宽和体质量,运用SPSS 22.0软件对不同性状的平均值、标准差、显著性检验.结果表明,与异源精子刺激产生的淇河鲫子代相比,同源精子刺激产生的后代生长性状较差.而黄河鲤精子刺激产生的子代生长性状最好.该实验支持并验证了“异精生物学效应”假说,为淇河鲫的种质资源保护和雌核发育研究提供参考,具有一定的社会和经济价值.
The Qihe crucian carp(Carassius auratus in Qihe river)is a unique and valuable fish in Henan province.Compared with common crucian carp,it is plump,brillante and nutritious.Reproductive way of feral Qihe crucian carp is natural gynogenesis,thus most of them are triploid.In this study,we selected 14 healthy mature female Qihe crucian carp,and mixed the eggs.Then we stimulated eggs of Qihe crucian carp with four mature sperms including Qihe crucian carp,Red purse carp,Red crucian carp,Yellow River carp respectively.After hatching,we measured the length,height,width and weight in 5-month old and 7-month old and analyzed the average of growth traits,standard deviation,and significance test using the SPSS 22.0 software.The results showed that comparing with homology sperm stimulation,the Qihe crucian carp offspring growth traits are better when heterologous sperm stimulation and the Yellow River carp stimulation is the best.Our study supports and verifies the allogynogenetic effect,providing a ponderable reference of crucian carp germplasm resources protection and gynogenesis breeding research.It has a definite social and economic benefits.
