| 摘要: | 为探究虎斑乌贼(Sepia pharaonis)喷墨对其行为、生长、存活及酶活的影响, 采用单因子试验法, 进行了喷墨虎斑乌贼(喷墨组)和未喷墨虎斑乌贼(对照组)的养殖比较试验, 试验时间30d. 研究结果表明, 虎斑乌贼喷墨后会导致其体色泛白、活力下降, 严重的会导致死亡; 养殖30d后,对照组虎斑乌贼的存活率、增重率和特定生长率均显著高于喷墨组(P<0.05); 特定生长率和增重率在试验时间≤10d时对照组显著高于喷墨组(P<0.05), 随着养殖时间延长, 2组无显著差异(P> 0.05); 喷墨组的抗氧化能力包括超氧化物歧化酶(SOD)活性、丙二醛(MDA)和谷胱甘肽(GSH)含量均显著高于对照组(P<0.05), 但过氧化氢酶(CAT)却显著低于对照组(P<0.05); 喷墨组的代谢酶包括谷丙转氨酶(GPT)和乳酸脱氢酶(LDH)的活性均显著高于对照组(P<0.05), 但酸性磷酸酶(ACP)的活性却显著低于对照组(P<0.05). 试验表明, 虎斑乌贼喷墨不仅会导致其生长缓慢、存活率下降, 并且会影响其体内相关酶的活性. |
| Abstract: | In order to explore the effects of Sepia pharaonis ink release on its behavior, growth, survival and enzyme activities, a single factor test method was applied to test the differences between ink release Sepia pharaonis (ink release group) and normal Sepia pharaonis (control group) over a period of 30 days. Following a large amount of ink release, cuttlefish Sepia pharaonis became pale, and had a low vitality with even severe deaths. The survival rate, weight gain rate, and specific growth rate of the control group were significantly higher than those of ink release group after 30 days (P<0.05). The growth rates and weight gain rates of the control group were significantly higher than those of the ink release group (P<0.05) during the first 10 days. There was no significant difference between the groups after the breeding period continued (P>0.05). The antioxidant capacity of the ink release group, including the superoxide dismutase (SOD) enzyme activity, the content of malondialdehyde (MDA) and glutathione (GSH) of the ink release group were significantly higher than those of the control group (P<0.05). Catalase (CAT) of the ink release group was significantly lower than that of the control group (P<0.05). Metabolic enzymes including alanine aminotransferase (GPT) and lactate dehydrogenase (LDH) of the ink release group were significantly higher than those of the control group (P<0.05). Acid phosphatase (ACP) activity of the ink release group was significantly lower than that of the control group (P<0.05). In conclusion, the ink release of Sepia pharaonis shall not only lead to its slow growth and low survival rate, but also affects the enzyme activities. |
