水温和饵料对宝石鲈稚、幼鱼生长和成活率的影响

Effetcts of temperature and food on the growth and survival rate of juveniles of Scortum bacoo

通过对宝石鲈稚、幼鱼在不同水温及饵料条件下的生长情况研究,初步确定宝石鲈稚、幼鱼最适生长水温为30℃左右;在试验选用的5种饵料中,卤虫是最适合其稚、幼鱼期生长发育的饵料。在最适条件下,宝石鲈稚、幼苗表现出最快的生长速度和较高的成活率。为宝石鲈的苗种培育提供了重要资料,直接指导了生产实践。

Growth and survival rate were measured with different temperature and food.According to our research,we can define preliminarily that the best temperature for juveniles of Scortum bacoo was around 30℃,and the best food organism in this research was artemia.With the best feeding conditions,juveniles of Scortum bacoo grew better and more fish survived after 15 days＇ feeding.This research was useful for culturing juveniles of Scortum bacoo in production practice.
