摘要
2009年4月在380m2的土池投放大弹涂鱼2龄亲鱼35kg,5月23日-29日和6月6日-11日先后产出两批仔鱼,共260万尾,于5月29日和6月11日晚采用管道通过自然落差移到室内育苗池,经45d-47d培育,育出幼鱼79.1万尾,平均全长为22.71mm,总成活率30.42%。试验表明把土池产出的仔鱼引到室内进行培育,是突破大弹涂鱼生产性育苗难关的有效方案。
In April 2009,some 2-year-old parent fish weighing 35kg were put in an earth pond of 380 m2.Then two batches of fish fries,totalling 2.6 million,were hatched during the following two periods： from May 23 to May 29 and from June 6 to June 11,and then piped into the indoor nursery pond by natural fall on May 29 and June 11 separately.After 45~47 days of nurture,791,000 young fish were obtained.The average body length of the fish was 22.71mm,and the general survival rate was 30.42%.The experiment shows that transferring fish fries from the earth pond to indoor nursery pond is an effective way of making a breakthrough in artificial breeding of Boleophthalmus pectinirostris.
