岱衢族大黄鱼放流增殖试验

Test on release and proliferation of Pseudosciaena crocea in Daiquyang sea area

  • 摘要: 为了恢复舟山渔场本地种岱衢族大黄鱼(Pseudosciaena crocea)资源,2000~2009年进行了岱衢族大黄鱼增殖放流试验。10年间共放流了经过人工繁育的岱衢族大黄鱼苗种1 288.0×104尾,其中包括标志鱼62 680尾。回捕标志鱼1 432尾,平均回捕率2.73%。回捕试验结果表明,在岱衢洋进行本地大黄鱼的放流可行,体外挂牌法适合于大黄鱼的标志放流,放流鱼苗不仅可以成活、生长,还能够产卵、增殖并进行洄游;放流使舟山渔场本地岱衢族大黄鱼资源得到显著恢复,并产生了一定的经济效益。

We released 1 288.0×104 artificially cultured fries including 62 680 tagged juveniles into Daiquyang; 1 432 fishes were recaptured after 2 months with an average recapture rate of 2.73%.Result shows that the release of the local P.crocea in Daiquyang sea area is feasible, and hanging scutcheon is suitable for the tagging and release.
