龙胆石斑鱼引种及人工育苗技术的初步研究

Study on the Introduction and Seed Breeding Techniques of Groper Epinephelus lanceolatus

从台湾引进龙胆石斑鱼受精卵 2 5 0 g ,35 .71× 1 0 4粒 ,孵出仔鱼 2 5× 1 0 4尾 ,经 6 1d培育 ,成功地培育出 33mm幼鱼 1 .0 381× 1 0 4尾 ,成活率 4 %。并针对初孵仔鱼、开口仔鱼、 30d稚鱼、 6 0d幼鱼。

fertilized eggs of Epinephelus lanceolatus weighed 250g was introduced and 25×10 4 larvae were hatched out.Through 61 days cultivation,1.038×10 4 larvae successfully grow into juvenile with 3.3cm long.The survival rate is 4%.Experiment and observation on growth and development characteristics of newly hatched larvae,and juvenile of 30 days,60 days and 90 days were carried out.
