摘要
为适应北方地区气候特点和市场需求,利用工厂化循环水系统培育反季节加州鲈苗种,在车间内进行饵料培育收集、水花下水、聚群饲养、饲料驯食、水质管理、筛苗分池等.采用 12 个培育池(总面积235.5 m2),每池投放水花 30 万尾,经过 40d培育,共产出 59.94 万尾苗种,平均成活率约为 16.65%.
Abstract
In order to adapt to the climate characteristics and market demand in the northern region,the factory circulating water system was used to cultivate anti-season Micropterus salmoides seed-lings.Techniques were applied,such as bait cultivation and collection,fry stocking,group feeding,feed taming,water quality management,screening and division of seedlings.12 ponds were stocked with a total area of 235.5 m2.Each pond was stocked with 300 000 fries.After 40 days of cultivation,599 400 seedlings were harvested with an average survival rate of 16.65%.
