摘要:
比较了-2,0,2,4,6℃等5种不同无水保活温度下,黑鲷(Sparus macarocephlus)的成活率、O2消耗量、CO2排放量、血清皮质醇及肌糖原的变化趋势。结果表明:在0℃条件下,无水保活36 h后,黑鲷成活率为100%,0℃组在整个无水保活过程中耗氧量最少,CO2释放量上升最缓慢,其皮质醇含量始终接近正常值,因此,0℃为黑鲷最佳无水保活温度。
Abstract:
Live fish of black seabream( Sparus macrocephlus) were stored without water at respective temperatures of -2 ℃,0 ℃,2 ℃,4 ℃ and 6 ℃,and their survival rate,O2 consumption,CO2 release,serum cortisol and muscle glycogen were determined and compared to choose an optimum temperature for waterless storage of the live fish. The results showed that the live fish of the black seabream stored without water at 0 ℃ had a survival rate of 100% even after 36 h,the least consumption of O2,and the slowest release of CO2,with their serum cortisol content always being closest to the normal value of the live fish. The temperature of 0 ℃ is hence optimal for waterless storage of the live fish of the black seabream.
