摘　　要：采用黄鳍鲷挂牌标志放流和流刺网探捕相结合的方法,开展对厦门湾黄鳍鲷增殖放流效果的评估.于2011年在厦门五缘湾增殖放流97万尾黄鳍鲷苗种,其中放流标志黄鳍鲷苗种15 036尾.结果表明,一年标志鱼回捕率为0.612%;放流标志鱼主要回捕海域为厦门湾大离浦屿—后田—刘五店—欧厝—小嶝岛邻近海域;放流黄鳍鲷在海区的生长情况良好,平均生长速度约0.56 g/d;经1 a时间,放流黄鳍鲷平均尾重约0.27 kg,形成资源量约263 t,形成捕捞产量约1.61 t;从2006到2011年每年进行增殖放流,结果使厦门湾黄鳍鲷种群的相对资源量比例提高了约3.83%.表明,黄鳍鲷增殖放流获得了一定的资源增殖效果.Using the methods of juvenile Sparus latus labeled with coded plastic tags released and fish captured by drift net,the evaluation on the effect of Sparus latus enhancement and release in Xiamen Bay was carried out.Of the 970000 juveniles of Sparus latus was released,15036 of which were labeled with coded plastic tags and released at Wuyuan in Xiamen Bay in 2011.The results showed that the tagged Sparus latus one year recaptured rate was 0.612%;the recaptured area was primarily around the Dalipu island,Houtian,Liuwudian,Oucuo and Xiaoden Island.The growth rate of the released fish in the sea was about 0.56g / d which is good considering that the average individual weight was 0.27kg in one year.Results also showed that the stock of Sparus latus increased about 263 tons,increasing the fishing yield about 1.61 ton.The enhancement and release of Sparus latus was carried out every year from 2006 to 2011.This resulted in the relative proportion of the stock of Sparus latus to fish resource amount in Xiamen Bay increasing about 3.83%.Therefore,the enhancement and release had some effect on enhancing the stock of Sparus latus in Xiamen Bay.
