| 摘 要： | 本文主要描述池塘养殖条件下鲥鱼幼鱼的生长与食性。1)1987-1989年8月至11月幼鱼生长迅速,快于同期珠江天然个体的生长速度;2)体长26.6-94.9mm的幼鱼主要摄食浮游动物,轮虫和浮游植物出现率随个体增大而减少。食物共有18个属种,摄食频度为100%;3)幼鱼的平均饱满指数为75.70‰。各类食物重量百分比的顺序为:桡足类>枝角类>无节幼体>虾类溞状幼体>轮虫>藻类。

| Abstract: | In this paper,the growth and feeding habits of young reeves shad under cultivated conditions are studied.The results show that the growth rate of cultivated juvenile is higher than that of natural ones.Young reeves shad of 26.6-94.9mm length mainly ingest zooplanktons,and the occurence rate of rotifera and phytoplanktons is decreased with the increasing length of shad. There are 18 genera of planktons ingested by shad, and the ingested frequency is 100%. The average fullness index of stomach is 75.70‰, and the weight percentage of various kinds of food is in order of copepoda>cleadocera>nauplius>zoea larva>rotifera>algae.d:\PDF\.pdf |
