摘要
报道了对西河华的年龄和生长的初步研究。用鳞片鉴定年龄,得出体长与体重的关系式。华的年龄组成由1~5龄个体组成,各龄鱼分别依序占标本总数的2.15%,40.86%,38.71%,17.20%和1.08%。该鱼在4龄以前生长较快,应限捕4龄以前的个体,以利于资源的增殖。
The paper is a findings report on the age and growth of Sarcocheilichthys sinensis blec-ker. The scales have been used to determine the age,the growth rate,and the relation between body weight,and length.The specimens are composed of one-year-to-five-year-old individuals,each occupying 2. 15%,40.86%,38.71%,17.20%,and 1.08%of the total number.The fish grows rapidly before 4 years old, and toprotect it from being endangered,it should not be caught before that age.
