花鲈人工育苗及当年养成技术研究

摘要

采用工厂化人工育苗方法,用6个月时间在13～17℃条件下培育出10～15 cm 大规格花鲈(Lateolabrax japonicus)鱼种42 000尾.育苗中饵料系列为轮虫(4～20 d)、卤虫(12～45 d)、配合饵料(20 d后)、鱼糜(45 d后).育苗期间最重要的技术环节为注意开鳔时间和减少互相残食.采用网箱养殖方式在大连地区当年平均可达500 g以上.

Abstract

Sea bass perch ( Lateolabrax japonicus ) juveniles with total length of 10-15 cm were produced within 6 months indoor. The feeding series was rotifer (4-20 d), artemia(12-45 d), formulated food (after 20 d), fish mince (after 45 d) In seedling rearing, improvement of rate of initial swim bladder inflation and of reduction of cannibalism was the key for fry rearing.The large juveniles reared in cages can reach more than 500 g within one growing season in Dalian
