摘要
通过评价机体内抗氧化酶活性、抗氧化能力、代谢产物及组织糖原、乳酸含量等变化,研究不同包装充氧方式和运输道路条件对有水活运过程中石斑鱼氧化应激的影响。研究表明:持续曝气及较低氧振动环境下的石斑鱼体内各抗氧化酶活、抗氧化能力、代谢产物虽有变化但并不显著,说明机体可自行调节维持抗氧化系统平衡;而极低溶解氧和持续曝气强振环境下的石斑鱼内各抗氧化酶活性、抗氧化能力、脂质代谢产物、无氧代谢产物力均随运输时间的延长变化显著,说明极低溶解氧含量、剧烈振动均会导致鱼体内自由基含量激增(无法及时清除),使鱼体氧化应激反应剧烈,破坏其抗氧化系统平衡。石斑鱼有水活运时,应根据运输距离长短和运输道路情况,设计不同的包装充氧方式以保证存活率。
By evaluating the changes of antioxidant enzyme activity,antioxidant capacity,metabolites,glycogen and lactic acid content in tissues,the effects of different packaging oxygenation modes and transport road conditions on oxidative stress of grouper during waterborne transport were studied.The resultsshowed that the antioxidant enzyme activity,antioxidant capacity and metabolites of grouper under continuous aeration and low oxygen vibration changed non-significantly,which indicated that the body could regulate and maintain the balance of antioxidant system.However,the activities of antioxidant enzymes,antioxidant capacity,lipid metabolites and anaerobic metabolic material production in grouper under very low dissolved oxygen and continuous aeration, and the strong vibration environment changed significantly with the prolongation of transport time.It indicated that very low dissolved oxygen content and the severe vibration could lead to a sharp increase in the content of free radicals in the body,which couldn’t be cleared in time,and the oxidative stress reaction was intense,destroying the balance of antioxidant system.It was concluded that different packaging oxygenation modes needed to be designed to keep the suitable alive rate, according to the distance and conditions of the transportation routing.
