杂交青虾“太湖1号”和日本沼虾抱卯量的比较研究

A Comgparative Study on Egg Production between the ＂Tai Lake NO. 1＂ and Macrobrachium Nipponense

比较研究了杂交青虾“太湖1号”和日本沼虾的绝对繁殖力与相对繁殖力。经统计分析表明：1、杂交青虾“太湖1号”的绝对繁殖力极其显著高于日本沼虾的绝对繁殖力（P〈0．01）；2、杂交青虾“太湖1号”的相对繁殖力极其显著高于日本沼虾的相对繁殖力（P〈0．01）；3、两种虾的抱卵量与体长、体重呈正相关，单位体长抱卯量与体长、体重也呈正相关，单位体重抱卵量与体长、体重无明显相关性。

Absolute fecundity and relative fecundity were studied and compared between the ＂Tai Lake NO. 1＂ and macrobrachium nipponense. The results showed that： 1 .The Absolute fecundity of The ＂Tai Lake NO.I＂ was significantly higher then macrobrachium nipponense （P 〈~ 0.01 ） ;2.The relative fecundity of The ＂Tai Lake NO.l＂ was significantly higher then macrobrachium nipponense （P 〈 0.01 ） ;3. There were positive correlation between egg production and body length and body weight and between egg production per unit length and body length and body weight, but there were no significant correlation between egg production per unit weight and body length and body weight.
