Abstract:

在对栉孔扇贝中国养殖种群(CC)、中国野生种群(CW)与俄罗斯种群(RW)及其杂交种群早期(2,3,4月龄)和中期(6,8,10,12月龄)生长发育研究的基础上,进行了各种群的1~2龄(14,16,19,21,24月龄)生长发育测定比较研究.结果表明,3个亲本群体各个性状的后期生长性能表现以中国养殖种群最好;2个杂交组合CC雌(♀)×RW雄(♂)和CW雌(♀)×RW雄(♂)的杂种群体各个性状的后期生长性能均高于纯种亲本种群,杂种优势均较大,其范围在3.16%~37.18%之间,以CC雌(♀)×RW雄(♂)杂交效果最好,是理想的杂交组合;壳长、壳宽、壳高、活体重4个生长发育指标在后期各个阶段均表现出不同程度的杂种优势,杂种优势在性状间存在明显差别,体重的杂种优势远大于壳宽、壳长和壳高,变化趋势为体重大于壳宽大于壳长大于壳高;栉孔扇贝各个性状的生长率受生长发育季节的影响较大,12~16月龄生长迅速,到16月龄(11月份)生长速度达到高峰,到下一年度的2月下旬(19月龄)几乎没有增长,仅能维持生命,开春以后增长也不大,这说明,栉孔扇贝在来年秋季完成了强度生长,是水产养殖的最佳收获时节,应当尽量避免跨越第二个冬季,以减少越冬损失.
