模拟运输对异育银鲫血液生理生化指标、体色和肉质的影响

EFFECTS OF SIMULATIVE TRANSPORTATION ON THE PLASMA BIOCHEMICAL INDICES, BODY COLOR AND FILLET QUALITY OF GIBEL CARP

  • 摘要: 实验以异育银鲫“中科3号”Carassis gibelio var. CAS III, 平均体重(116.46±2.09) g)为研究对象, 通过模拟汽车运输振动台模拟4h运输, 研究模拟运输对异育银鲫血液生理生化指标、体色和肉质及水质的影响。研究结果表明: 经过模拟运输后, 运鱼袋内水体氨氮显著升高(P<0.01), pH显著下降(P<0.05), 溶解氧含量升高(P<0.05)。模拟运输后异育银鲫血浆中皮质醇、葡萄糖和丙二醛浓度显著升高(P<0.01); 乳酸浓度显著降低(P<0.01); 谷胱甘肽过氧化物酶活力显著降低(P<0.05); 超氧化物歧化酶和过氧化氢酶活力降低但差异不显著(P>0.05)。在模拟运输4h后, 异育银鲫背部亮度值(L*)显著降低(P<0.01), 黄色值(b*)在背部和侧线部较模拟运输前显著降低(P<0.01), 在腹部较模拟运输前显著降低(P<0.05), 侧线部和腹部的亮度值(L*), 以及背部、侧线部和腹部的红色值(a*)下降但差异不显著(P>0.05)。在模拟运输后, 异育银鲫背肌内聚性、咀嚼性和回复性显著降低(P<0.05), 硬度、胶黏性、弹性和黏性变化但差异不显著(P>0.05)。实验结果表明, 4h模拟运输能够引起运鱼袋水体水质情况改变, 诱导异育银鲫鱼体的应激反应, 导致实验鱼体色和鱼肉品质相关指标的变化, 降低了鱼肉品质部分指标。

     

    Abstract: This study was conducted to investigate the effect of transportation stress on the plasma biochemical indices, body color, fish quality of gibel carp Carassis gibelio var. CAS III, body weight of (116.46±2.09) g and water quality. Transportation was simulated on an automobile vibration bench for 4h. After 4h simulative transportation, the ammonia concentration of water in bags increased significantly (P<0.01), and the dissolved oxygen of water in bags was increased (P<0.05), while the pH value decreased significantly (P<0.05). Fish plasma cortisol, glucose and MDA concentration increased significantly (P<0.01), while plasma lactic acid concentration decreased (P<0.01). Plasma GSH-PX significantly decreased after 4h simulative transportation (P<0.05), and plasma SOD and CAT had a low value after simulative transportation (P>0.05). Dorsal skin showed significantly decreasing L* values after 4h simulative transportation (P<0.01), and the abdomen and lateral line L* values also decreased with no significance (P>0.05). While a* (P>0.05) and b* (P<0.05) values declined in these three parts after 4h transportation. Cohesiveness, chewiness and resilience decreased significantly in fillet (P<0.05). The fillet gumminess, springiness and adhesiveness were slightly decreased (P>0.05), while its hardness increased (P>0.05). The results indicated that transportation could induce stress response of gibel carp and reduce fish quality.
