罗氏沼虾亲虾越冬技术的探讨

A Study of Broodstock Wintering Technology of Macrobracium rosenbergii

罗氏沼虾亲虾越冬是育苗的关键，采用大水体高水位、设置隐蔽体、引入水葫芦、伴养鳙鱼、多种饵料组合、交叉投喂、偏低温越冬等技术举措，能提高亲虾越冬成活率、育苗孵化率．本实验亲虾越冬成活率为９８％．每尾抱卵亲虾孵出１．９３万尾状幼体．

acrobracium rosenbergii broodstock wintering is the key to breeding.Making use of large water body with higher water level, introducing acquatic plants, being polycultured, with bighead carps, mixing with many types of fodder, feeding intervally and wintering at a lower temperature can raise the survival and brooding rates of Mao7xibraciumrosenbergii.The experiment shows that the survival rate of the wintering broodstocks is98%. Every broodstock breeds 19300 zoeas.
