摘要:

本文通过比较暗纹东方鲀(Takifugu obscurus)幼鱼在淡水与海水养殖期间的个体生长指标,测定消化酶和非特异性免疫酶活性、肌肉生化组分,探讨淡水养殖对其生长和生理的影响。结果表明,淡、海水养殖的暗纹东方鲀幼鱼的体长、体质量增长受养殖水盐度的影响极显著(P<0.01),淡水组幼鱼生长指标优于海水组;淡水组暗纹东方鲀幼鱼钠-钾ATP酶(Na+/K+-ATPase)活力显著小于海水组,溶菌酶(LZM)活力显著大于海水组(P<0.05);抗氧化酶活力、消化酶活力和肌肉生化组分在淡、海水组之间无显著差异(P>0.05)。相较于海水养殖,淡水养殖更有利于暗纹东方鲀的生长。本研究结果可以为暗纹东方鲀淡水规模化健康养殖提供科学数据。

Abstract:

By comparing the individual growth indicators of Takifugu obscurus juveniles during freshwater cultured and seawater cultured, the activities of digestive enzymes and non-specific immune enzymes, and muscle biochemical components were determined to explore the effects of freshwater culture on growth and physiology of T.obscurus juveniles. The results showed that the body length and body mass growth of T.obscurus juveniles in the freshwater groups and seawater groups were significantly affected by the salinity, and the growth indexes of the juveniles in freshwater group were better than those in the seawater group (P<0.01). The activity of Na+/K+-ATPase was significantly lower than that of the seawater group, and the LZM activity was significantly higher than that of the seawater group (P<0.05). There were no significant differences in the activities of antioxidant enzymes, digestive enzymes and muscle biochemical components between the freshwater groups and seawater groups (P>0.05). Compared with seawater culture, freshwater culture was more conducive to the growth of T.obscurus. This study could provide scientific data for T.obscurus large-scale healthy farming.
