黄鳝血清总脂含量与体长关系的研究

目的]为了探讨黄鳝血清总脂含量与体长的相关性。方法]以处于繁殖季节的体长为19.3～68.0 cm的53尾黄鳝为研究对象,采用香草醛法测定不同体长黄鳝的血清总脂含量,并分析体长与黄鳝血清总脂含量的关系。结果]黄鳝血清的总脂含量为3.94～11.61 mg/ml。黄鳝体长(x)与血清总脂含量(y)间的回归方程为y=5.526 1 x+392.7(r=0.373 8),说明两者间存在显著正相关。结论]在繁殖期间黄鳝血清总脂含量随体长变化不大,这使黄鳝在繁殖期间血清总脂含量处于较稳定的生理状态。

Study on the Relationship between Body Length and Total Lipid Content in Serum of Monopterus albus

Objective] The research aimed to discuss the relationship between body length and total lipid content in serum of Monopterus albus.Method] With 53 fishes of M.albus with body length of 19.3～68.0 cm in reproductive season as research objectives,total lipid contents in serum of M.albus with different body lengths were determined by vanillin method and the relationship between body length and total lipid content was analyzed.Result] Total lipid content in serum of M.albus was 3.94～11.60 mg/ml.The regression equation between body length of M.albus(x) and total lipid content of serum(y) was: y=5.526 1x+392.7(r=0.373 8),indicating that they had significantly positive relation.Conclusion] In reproduction period the total lipid content in serum of M.albus had not great change with body length,which made total lipid content in serum of M.albus in reproduction period in steady physiological state.
