泥河水库鲢、鳙鱼生长规律的研究

摘要

本文研究了泥河水库鲢鳙鱼的生长规律，根据莱亚的鱼体长和鳞长的关系式Ln/L＝Sn/S分别推算出鲢鱼和鳙鱼的生长速度体长增长值；并计算出泥河水库鲢鳙鱼的体长与体重的关系、肥满度和生长方程。体长和体重的关系式分别为：鲢鱼W＝0.4133L2.2011，鳙鱼W＝0.02395L2.9444；肥满度分别为：鲢鱼K=1.779，鳙鱼K＝1.936；生长方程分别为：rn　　鲢鱼：Lt＝126.87〔1－e－0.0963(t+0.1566)〕rnWt＝46021〔1－e－0.0989(t-1.1293)〕3rn　　鳙鱼：Lt＝149.36〔1－e－0.0912(t+0.2355)〕rnWt＝96530〔1－e－0.0792(t-0.2532)〕3%This paper is about the growth of Aristichthys nobilis and Hypophthalmichthys molitrix on the basis of Einar Lea in Nihe reservoir.The Fulton coefficients were WH=0.4133L2.2011，WA＝0.02395L2.9444.The growth equations were LH＝126.87〔1－e－0.0963（t+1566)〕，WH＝46021〔1－e－0.0989（t－0.1293）〕3，LA＝149.36〔1－e－0.0912(t+0.2355)〕，WA＝96530〔1－e－0.0792(t－0.2532)〕3.
