摘要:
为探讨低盐养殖对大黄鱼生长、体成分及抗氧化能力的影响,挑选初始体重为(53.59±25.10)g的大黄鱼幼鱼600尾,分为对照组(天然海水,盐度24)和低盐组(盐度10)两组,每组设3个重复,进行为期60 d的养殖试验。试验结果表明:低盐养殖大黄鱼增重率及特定生长率显著高于对照组(P<0.05);肌肉的粗蛋白质和粗灰分含量分别显著高于和低于对照组(P<0.05),粗脂肪略低于对照组,但没有显著差异(P>0.05);低盐组大黄鱼肌肉∑MUFA显著低于对照组,而∑PUFA显著高于对照组(P<0.05);低盐养殖组大黄鱼肝脏与肾脏组织中总抗氧化能力(T-AOC)、过氧化氢酶(CAT)活性显著高于对照组(P<0.05);超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-PX)活性及丙二醛(MDA)含量均显著低于对照组(P<0.05)。
Abstract:
In order to investigate the effects of low salinity culture on the growth,muscle nutritional composition and antioxidant capacity of large yellow croaker(Larimichthys crocea),a total of 600 juvenile large yellow croaker with an initial body weight of(53.59±25.10)g were randomly divided into two groups(natural seawater group,salinity 24;low salinity group,salinity 10) with three replicates per group.Fish were reared in an indoor cement tank(2.5m×1.2m×0.8m)for 60 d.The results showed that the weight gain rate(WGR)and specific growth rate(SGR)of fish in low salinity group was significantly higher than those in the control group (P<0.05).The contents of muscle crude protein and ash of large yellow croaker in the low salinity group were significantly higher and lower than those of the control group,respectively.There was no significant difference in the muscle crude lipid between two groups (P>0.05).The ∑MUFA content in muscle of the large yellow croaker in low salinity group was significantly lower than that in the control group,while the ∑PUFA content was significantly higher than that in the control group (P<0.05).The total antioxidant capacity(T-AOC) and catalase(CAT) activity in liver and kidney of large yellow croaker in low salinity group were significantly higher than those in control group (P<0.05).But the activity of superoxide dismutase(SOD),glutathione peroxidase(GSH-PX) and the content of malondialdehyde(MDA) in liver and kidney of large yellow croaker in control group were significantly higher than those in low salinity group (P<0.05).
