海捕野生曼氏无针乌贼选育F_1的生长
|
摘要
2016年从诏安海域捕捞的野生曼氏无针乌贼中,挑选2000尾平均胴长(12.12±0.15)cm、体质量(203.88±14.82)g的成熟个体人工繁育出子代(F_1)后,室内常规饲养,与未经选育的对照组子代的生长性状进行比较。结果显示,拟合0~90日龄体质量(y)与胴长(x_1)、体质量(y)与胴宽(x_2)的生长式型,选育F_1组生长关系y=0.2272x_1~(2.6506)(r~2=0.9825),y=0.5356x_2~(2.9824)(r~2=0.9845),对照组生长关系为y=0.2894x_1~(2.5781)(r~2=0.9953),y=0.6802x_2~(2.7145)(r~2=0.9725),选育F_1组的生长快于对照组;选育F_1组体质量绝对增加率为0.03~0.69g/d,绝对增长率为0.017~0.123cm/d,增积量为0.0001~0.0788,肥满度为0.104~0.374,优于对照组;选育F_1组胴长、胴宽和体质量的现实遗传力分别为0.033~0.599、0.015~0.244和0.001~0.294,说明选育具有一定的效果。
Selective breeding F_1offsprings from 2000individuals of wild cuttlefish Sepiella maindroni with body weight of(203.88±14.82)g were reared in an indoor tank to evaluate growth performance compared with the cuttlefish in the control group.The results showed that the fitting formula between body weight(y)and body length(x_1),and between body weight(y)and body width(x_2)in 90days were described as y=0.2272x_1~(2.6506)(r~2=0.9825),and y=0.5356x_2~(2.9824)(r~2=0.9845)for the F_1offsprings and as y=0.2894x_1~(2.5781)(r~2=0.9953),and y=0.6802x_2~(2.7145)(r~2=0.9725)for the cuttlefish in the control group.There was better growth in selective breeding F_1than the individual in the control group,with absolute weight gain of(0.03-0.69)g/d,absolute length gain of(0.017-0.123)cm/d,and condition factor of 0.104-0.374,for the selective breeding F_1.The breeding F1had realized heritability of 0.033-0.599in body length,0.015-0.244in body width and 0.001-0.294in body weight,showing the effects of selective breeding.
