中华绒螯蟹"长荡湖1号"选育第二代扣蟹阶段养殖性能研究
A evaluation on culture performance of second selective generation of Chinese mitten crab(Eriocheir sinensis)"Changdang Lake 1"during juvenile culture stage
摘要
Abstract
To evaluate the breeding effect of the second generation(G2)of"Changdang Lake 1"Strain A and Strain B Chinese mitten crab(Eriocheir sinensis),the juvenile culture experiment was conducted with the unselected population as control.The results showed that:(1)The average body mass,weight gain multiple and survival rate of Strain B were significantly higher than that of control group during the pea-sized juvenile rearing stage(P<0.05),and Strain A also had higher growth performance than the control but no significant difference was observed.(2)The average body weight of crabs in Strain B has always been significantly higher than that of control group during the pea-sized juvenile and coin-sized juvenile culture period(P<0.05).The average body weight of Strain A was also significantly higher than the control with the exception of September(P<0.05),and the growth rate of both Strain A and B were significantly higher than the control between June and July(P<0.05).(3)Crabs in Strain B showed the highest culture performance,in terms of significantly higher survival and yield,as well as significantly lower precocious rate and feed coefficient ratio(P<0.05).(4)For size distribution,the proportion of Strain A and B was lower than that of the control group in the intervals of 3.00-5.99 g and 6.00-8.99 g,and significantly higher than the control in the intervals of 12.00-14.99 g and≥15.00 g(P<0.05).Overall,"Chang-dang Lake 1"G2 has the advantages of fast growth,high survival rate and large average size at the juvenile culture stage.关键词
