摘要
在１０个面积均为１５ｍ２的实验池中，分三批放养全长６～９ｍｍ的南方大口鲶鱼苗共４．１５２万尾，经４０～５０天培育，获全长６～８ｃｍ的鱼种２．３２５万尾，出池率５６％。还结合生产情况及室内实验结果，分析了水温、放养密度及饵料对苗种成活和生长的影响，拟合了苗种体重与全长，日龄与全长及日均增长率的回归关系。
A total number of 41520 large-mouthed catfish fry with 6-9 mm in total length were stocked in three batches into ten experimental tanks, 15 M2 each. After 40-50 days of rearing, 23250 fingerlings with 6-8 cm in total length were harvested,and the survival rate was 56%. Combined with the production and indoor experiment results,the influence of water temperature,stocking density and food on seed survival and growth were analysed. Regressive correlations between the seed body weight and total length,age in days and total length,and the average daily growth rate were analogized as well.
