| 摘 要： | 2012年5-10月，在面积为0.19hm2的试验池1中放养体质量160g的松浦镜鲤（Cyprinus carpio Songpu）117,700尾·hm^-2，混养体质量160g的长丰鲢（Hypophthalmichthys molitrix）春片、乌子头和鳙（Aristichthys no-bilis）夏花鱼种。在面积为0.19hm2的试验池2中放养体质量149.5g的松浦镜鲤3,450尾·hm^-2，只混养鲢和鳙夏花，采用常规饲养方法。2012年10月2日，试验池1平均每hm2产鱼21,025.5kg,其中松浦镜鲤平均全长34.3cm，体质量1425g，产量18,294.0kg；长丰鲢春片平均体质量674g，平均产量1,816.5kg，长丰鲢夏花平均全长18.6cm，体质量112.4g，平均产量592.5kg；鳙夏花平均全长达12.1cm，体质量39.9g，平均产量322.5kg。试验池2平均每hm2产鱼3,069.0kg，其中松浦镜鲤平均全长35.0cm，体质量1225g，平均产量2,766.0kg；鲢夏花平均全长达11.3cm，体质量24.9g，平均产量130.5kg；鳙夏花平均全长达11.1cm，体质量35.1g，平均产量172.5kg。试验表明，高密度养殖的松浦镜鲤产量显著高于密度低时，长丰鲢夏花的出池体质量是普通鲢的4.5倍，特殊生长率（6.27%·d^-1）是普通鲢（3.5%·d^-1）的1.79倍。文中还讨论了松浦镜鲤养殖池的水质和技术特点。

| Abstract: | Songpu mirror carp （Cyprinus carpio Songpu） juveniles with initial body weight of 160g was stocked into Test Pond 1 at a rate of 17,700 individuals·hm^-2, and polycultured with Changfeng silver carp（Hypophthalmichthys molitrix） juveniles with initial body weight of 160g and 0.10g and bighead carp （Aristichthys nobilis） with initial body weight of 0.16g from May to October in 2012. In Test Pond 2, however, Songpu mirror carp juveniles weighing 149.5 g was stocked at a rate of 3,450 individuals·hm^-2, and polycul-tured with silver carp and bighead carp summerlings. Average fish yield of 21,025.5 kg·hm^-2 was harvested in Test Pond 1 on 2 Octo-ber, 2012, including 18,294.0kg of Songpu mirror carp with final body weight of 1425g, Changfeng silver carp with final body weight of 674 g and 112.4 g of 2,409.0kg, and bighead carp with final body weight of 39.9g of 322.5kg. Only 3,069kg of fish was harvested in Test Pond 2 on 2 October, 2012, including 2,766.0kg of Songpu mirror carp with body weight of 1225g, 130.5 kg of Changfeng silver carp weighing 24.9g, and 172.5kg of bighead carp averaging 35.1g. It was found that there was higher Songpu mirror carp yield at the higher stocking density than that at the lower stocking density. The Changfeng silver carp was found to has the final body weight as 4.5 time as the silver carp, and to has the specific growth rate（6.27%·d^-1）as 1.79 time as the silver carp（3.5%·d^-1）. The water quality and key techniques are discussed in food fish polyculture of Songpu mirror carp with Changfeng silver carp in a pond in northern China. |
