1997年在大亚湾开展了真鲷 Pagrosomus major 的标志放流研究，以探讨人工放流增殖大亚湾真鲷资源的可行性。标志放流的真鲷共2 000尾，体长为 57──71mm（平均体长为 61mm）。标志放流效果明显，共回捕标志真鲷324尾，回捕率达16．2％，初步了解了标志真鲷在大亚湾内的分布移动趋势及生长等情况。
In 1997, the flag release study on Pagrosomus major of the seabream was carried out in Daya Bay to investigate the feasibility of using artificial seeding to proliferate the resources of the Daya Bay seabream. A total of 2,000 red sea breams were released with a body length of 57-71 mm (average body length of 61 mm). The marked release effect was obvious. A total of 324 traps of the red sea bream were recovered and the rate of return was 16.2%. The distribution trend and growth of the flag sea bream in the Daya Bay were initially obtained.
