团头鲂耐低氧F_4代和“浦江1号”1、2龄鱼生长速度比较
|
摘要
为评估团头鲂耐低氧F_4代的选育效果,在上海市浦东和青浦2个试验点采用剪鳍标记和同池比较法对团头鲂耐低氧F_4代(选育组)和"浦江1号"(对照组)1、2龄阶段的体质量绝对增长率进行了比较。结果显示:浦东试验点选育组1、2龄阶段的体质量绝对增长率比对照组分别高24.7%和20.9%,青浦试验点选育组1、2龄阶段的体质量绝对增长率比对照组分别快24.4%和20.9%。结果表明,团头鲂耐低氧F_4代(选育组)1、2龄鱼的生长速度优于"浦江1号"(对照组),团头鲂耐低氧F_4代在经过系统选育后,其生长特性和养殖效果显著提高。试验结果对于团头鲂耐低氧新品系的选育及推广具有参考意义。
