Effect of continuous cooling on metabolic function of adult Scophthalmus maximus L
摘要
Abstract
In order to study the effect of continuous cooling on metabolic indices of serum, liver and muscle, the adult turbot was subject to continuous cooling from 18 to 1℃, and 6 individuals were collected at each specific temperature including 18, 13, 8, 5, 3 and 1℃. The contents of liver glycogen, lactic acid of muscle and eight serum biochemical indices were measured including total protein, albumin, glucose, total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol, triglyceride and urea. The results showed that the total protein had significant difference between 13 and 3℃, albumin had significant difference between 3 and 1℃, total cholesterol had significant difference between 18 and 3℃, urea had significant difference between 8 and 1℃, contents of lactic acid in muscle had significant difference between 18 and 5℃.The contents of glucose in the 8, 5 and 1℃ groups were significantly higher than those in other groups. The contents of liver glycogen in the 8, 5 and 1℃groups were significantly higher than those in other groups. In addition, other indices showed no significant difference in the temperature change. The results showed that when the temperature ranged from 18 to 8℃, the metabolism changed quite little, when the temperature decreased from 8 to 3℃, the stress response appeared, when the temperature continuously decreased to 1℃, the metabolism tended to be extremely low, even stoped. According to the analysis of the data, a conclusion can be drawn that temperature between 3 and 1℃ was close to the ecological ice temperature of Scophthalmus maximus, so further exploration of anhydrous transport could be made in this temperature range to lessen the cost.关键词
