| 摘 要： | 本研究以中华绒螯蟹2龄早熟和晚熟群体选育第四代(G4)的扣蟹为对象,并以未经选育的养殖群体扣蟹为对照组,采用养殖实验、免疫指标测定和攻毒实验等方法,从生长性能和免疫抗病性能的角度分析并评价不同群体的蟹种质量。结果显示:①养殖实验中两选育群体的最终体质量和特定增长率(SGR)均优于对照组,且2龄早熟群体在8-11月的平均体质量始终低于晚熟群体,但差异不显著;②养殖效果方面,三群体成活率和最终产量由大到小依次为早熟G4、晚熟G4和对照组,三群体1龄早熟率的大小次序与之相反,其中雌体产量和1龄早熟率差异显著;③免疫指标方面,两选育组碱性磷酸酶(AKP)和酸性磷酸酶(ACP)活性以及总抗氧化能力(T-AOC)水平均高于对照组,其中雄体肝胰腺中AKP活性以及雌体血淋巴中T-AOC水平差异显著;④两选育群体在攻毒实验中最终死亡率均较低,分别比对照组低29.50%和22.94%。研究表明,选育G4扣蟹的生长性能和免疫抗病相关生理指标都表现出了比未选育群体优良的特性,市场应用和产业化前景广阔。

| Abstract: | When breeding for some specific parameters,relevant parameters always undergo covariation.A selective breeding program has been operated on Eriocheir sinensis for different mature time and culture performance equally since 2011,but crabseed quality of selected populations has not been evaluated yet.This study was aimed to evaluate the crabseed quality of two selected populations(early-maturing strain:EM,latematuring strain:LM)compared to pond-reared crabseed without selection(control).The results showed that:①The final weight and specific growth rate(SGR)of two selected populations were both relatively higher than those of the control all through the experiment,and the average weight of EM was lower than the LM between August and November,but no significant difference was observed.②The order of survival rate and final yield was EM>LM>control with significant difference in yield of females,the order of precocious rate was opposite with significant difference in females as well.③As for the immune index,the levels of alkaline phosphatase(AKP),acid phosphatase(ACP)and total antioxidant capacity(T-AOC)in hepatopancreas and hemolymph of both selected populations were higher than the control,with significant difference of ALP level in hepatopancreas of females and significant difference of T-AOC level in hemolymph of males.④The injection of Aeromonas hydrophilia resulted in both lower(29.50%and 22.94%,respectively)cumulative mortalities of two selected populations.In conclusion,selection for different mature time and culture performance of E.sinensis also presented an effective improvement in their crabseed quality. |
