摘　　要：2004年-2006年分别采用金属线码标记、荧光色素可见式标记(荧光标记)和挂牌标记三种方法,在舟山海域进行黑鲷(Sparus macrocephalus)标志放流试验,三年内共放流标志黑鲷17 616尾,平均体长131.9 mm,平均体重46.46 g。结果表明:挂牌标记的死亡率和脱标率最高,荧光和挂牌标志鱼只获得当年回收,回捕率分别为0.16%和0.64%,没有捕获金属线码标志鱼,说明在开放性的水域,总体回捕结果不佳,金属线码标记法不适合黑鲷放流;标志黑鲷移动范围不大,最远不超过15海里,栖息地具有明显的区域性;标志鱼放流后2个月左右生长缓慢,此后生长加快。本试验基本达到标志放流的预期目的。The experiment of tagging and releasing Sparus macrocephalus （Basilewsky） was carried out in 2004, 2005 and 2006 using three tagging methods of coded wire tag, visible implant elastomer tag and scutcheon tag respectively in the Zhoushan sea area. In 3 years, 17616 Sparus macrocephalus with average body length of 131.9 mm and average body weight of 46.46 g were tagged and released. The mortality and lost tag rate of scutcheon tag is the highest of all, The fish with visible implant elastomer tag and scutcheon tag were recaptured in the same year and the recapture rate were 0.16 % and 0.64 % respectively, and there was no recapture of fish with coded wire tag. All the results showed that in the open sea area the recapture rate was low, and the wire tag was not fit for the tagging and releasing of Sparus macrocephalus. Otherwise, the migration area of the tagged Sparus macrocephalus was small and the longest distance was 15 nautical miles and the territorial habitat was distinct. In addition the tagged Sparus macrocephalus grow slowly in 2 months after being released and then grow faster. All desired results were obtained in this experiment.
