摘要
为了研究台风过境对养殖三疣梭子蟹的影响,于2015年7月采集"灿鸿"台风经过象山前后12h内象山三疣梭子蟹养殖场样品,检测台风前后三疣梭子蟹中T-SOD、CAT、ACP、Na^+,K^+-ATP酶活性以及MDA、GSH含量的变化。结果显示:台风过后鳃中T-SOD酶活性升高极其显著(p<0.01);CAT酶活性显著升高(p<0.05);MDA和GSH含量则呈现增加趋势,但差异不显著(p>0.05)。肝胰腺中T-SOD酶活性呈现降低趋势,但差异不显著(p>0.05);CAT酶活性呈现升高趋势,差异不显著(p>0.05);MDA含量显著增加(p<0.05);GSH含量增加极其显著(p<0.01)。心脏中T-SOD、CAT酶活性和GSH含量呈现增加趋势而MDA含量呈现降低趋势且差异均不显著(p>0.05)。心脏和鳃中ACP酶活性呈现上升趋势,肝胰腺中ACP酶活性降低,但差异都不显著(p>0.05)。Na^+,K^+-ATP酶活性在鳃中极显著下降(p<0.01),在肝胰腺中酶活性极显著上升(p<0.01),在心脏中酶活性显著上升(p<0.05)。结果表明台风会造成三疣梭子蟹短期内应激反应,如若不尽快采取措施,后期会对三疣梭子蟹造成较大的损伤。
In order to study the effect of typhoon on the cultured Portunus trituberculatus,the changes of T-SOD,CAT,MDA,GSH,ACP and Na^+,K^+-ATPase in the hearts,gills and hepatopancreas were detected in 12hours before and after typhoon "Canhong"(1509)at Xiangshan in July,2015.The typhoon increased highly significantly the activity of the T-SOD enzyme (p%0.01)and increased significantly CAT enzyme(p<0.05)in the gills.After typhoon,the MDA and GSH content in gills increased insignificantly (p>0.05).T- SOD enzyme activity in the hepatopancreas showed an insignificant trend of decrease (p>0.05)while the CAT enzyme activity showed an insignificant trend of increase (p>0.05),MDA content increased significantly (p<0.05)and the increase of the GSH content was highly significant (p<0.01).In the hearts, the levels of T-SOD,CAT enzyme activity and GSH content increased and the MDA content decreased,but these changes were not significant(p>0.05).In addition,the ACP enzyme activity in the gills and the hearts increased insignificantly (p>0.05),which was reduced but not significantly in the hepatopancreas (p>0.05).The Na^+,K^+-ATPase activity in the gills decreased highly significantly (p<0.01),but increased highly significantly in the hepatopancreas (p%0.01)and significantly in the heart (p<0.05).This study reveals that the typhoon can cause the cultured P.trituberculatus stress response in the short term and solutions are need to take to avoid typhoon damage to cultured P.trituberculatus.
