日本沼虾

瓶颈效应和突变-漂移平衡分析表明，鄱阳湖日本沼虾群体近期没有经历过瓶颈效应，群体数量也没有下降。

Bottleneck effect and mutation-drift equilibrium tests indicated that the M.nipponense populations in the Lake did not suffer bottleneck effect , and had no decline in their quantity in recent time .

结果表明，将日本沼虾太湖群体作为母本，鄱阳湖群体作为父本进行杂交，可获得显著的杂交优势。

All of above , the obvious heterosis in growth performance could be achieved through the cross of M.nipponense populations between Taihu Lake (♀) and Poyang Lake (♂) .
