摘要: 探究不同包装密度和运输时间对金鱼[体重(41.63±1.00)g,体长(10.35±0.40)cm]行为状态、存活率、水质指标和抗氧化能力的影响。采用塑料袋打包法模拟运输,设置4个打包密度(A为12尾/包、B为16尾/包、C为20尾/包和D为24尾/包)和4个运输时间(24 h、48 h、72 h和96 h)。研究结果显示随各运输组打包密度增加或运输时间增长,溶解氧、pH值呈降低趋势;亚硝酸盐、氨氮含量呈升高趋势;金鱼肝脏T-AOC氧化应激水平呈先升高后降低趋势;SOD活力和CAT活力呈不同程度降低趋势;A、B组的金鱼显示出更好的抗氧化能力和较低的应激反应,存活率显著高于C、D组。研究表明,运输48 h内可采取较高的打包密度(24尾/包),如需长途运输72 h,建议打包密度为20尾,96 h建议打包密度为16尾,不建议以12尾/包密度打包运输。

Abstract: This study was carried out to explore the influence of different packing density and transportation time on the behavior and status [body weight(41.63±1.00)g, body length(10.35±0.40)cm], survival rate, water quality index and antioxidant capacity of grass goldfish. Transportation was simulated by plastic bag packing with 4 packing densities(i. e. A 12 tails / pack, B 16 tails / pack, C 20 and D 24 tails / pack)and 4 transportation times(24,48,72 and 96 h). The results showed that the dissolved oxygen and pH decreased; The content of nitrite and ammonia nitrogen increased; The T-AOC oxidative stress increased and then decreased; SOD activity and CAT activity decreased to different degrees; The grass goldfish in groups A and B showed better antioxidant resistance and lower stress response, and the survival rate was significantly higher than those of groups C and D. The study shows that a high packing density(24 tails/pack)is adopted within 48 hours of transportation, 20 tails is recommended for 72 hours, 16 tails for 96 hours, but 12 tails/pack is not recommended as packing density(physical damage due to excessive activity space).

Key words: grass goldfish, transportation density, transportation time, water quality index, antioxidant capacity
