摘　　要：人工饲养的广东鲂 ,其仔、稚鱼的体长与日龄呈直线相关 ;体重与日龄、体长与体重均呈幕函数相关。它们的生长与水温及放养密度的关系亦相当密切。初步提出生长的最适水温范围和适宜放养密度。此外还对仔、稚鱼作了消化管发育的观察和食性的分析。广东鲂仔。The growth characteristics of Megalobrama hoffmannis fingerlings have been observed. The relationship of body length/day falls on a straight line while that of weight/day and length/weight are exponential. The growth rate of fingerlings is closely related to water temperature and stocking density. The suitable water temperature and proper stocking density are recommended. The development of degestive tract and feeding habit during the early larval stage are also observed. The feeding habit of the fingerlings is omnivorous with a tendency to carnivorous.
