The experiment of tagging and releasing Sparus macrocephalus 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.

2004年-2006年分别采用金属线码标记、荧光色素可见式标记和挂牌标记三种方法，在舟山海域进行黑鲷标志放流试验，三年内共放流标志黑鲷17 616尾，平均体长131。

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 mcicrocephalus. 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.

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。

The experiment of tagging and releasing Sparus macrocephalus 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 effects of feeding frequencies(1, 2, 3 and 4 times per day) on the growth of Sparus macrocephalus were studied in a 40 d growth trial under the condition of 26.8~24.5℃, 26.0~27.0 salinities for determining the optimum feeding frequency. Identical diet was selected for the mature and seedling of Sparus macrocephalus in the aquiculture system.

选取同一种饵料设置4个饲喂频率水平（分别为1次／d、2次／d、4次／d、6次／d），采用静水连续充气养殖系统，在盐度为26.0~27.0、温度为26.8~24.5℃的条件下对黑鲷成鱼和鱼种进行为期40d的生长实验。

In addition, both the moisture content of the mature and seedling of Sparus macrocephalus and the fat content of seedling of Sparus macrocephalus increased with the growing of feeding frequency, whereas the fat content of mature Sparus macrocephalus decreased with the growing of feeding frequency.

2黑鲷成鱼和鱼种的水分含量随饲喂频率的增高而增加，黑鲷成鱼脂肪含量随饲喂频率的增高而下降，黑鲷鱼种脂肪含量随饲喂频率的增高而增加。

In this study, the malondialdehyde content, the glutathione peroxidase activity, and the superoxide dismutase activity in black porgy Sparus macrocephalus were determined after the acute exposure to TBTCl at the concentration of 4 and 20 μg·L-1. Results showed that TBTClinhibited the SOD activity in S.macrocephalus gill slightly , but there was an obvious promotion on the SOD activity in S.macrocephalus liver.

摘 要：观察和比较了黑鲷 Sparus macrocephalus 在不同浓度的氯化三丁基锡（tri-n-butyltin chloride，TBTCl）溶液中暴露后，其鳃和肝脏组织中超氧化物歧化酶（superoxide dismutase，SOD）活性、丙二醛（malondialdehyde，MDA）含量和谷胱甘肽过氧化物酶（glutathione peroxidase，GPx）活性的变化情况。
