| 摘 要： | 1984～1986年在山东南部沿海八大港湾同步增殖放流体长3cm以上的虾苗14.9116亿尾,累计回捕增殖对虾1.4亿尾,平均回捕率为9.4％,其中拖网回捕增殖对虾累计为1184.7t,但损害的七种经济幼鱼累计为4402t,应引起重视这一问题。

| Abstract: | During the period of 1984~1986,1949.16 million juvenile prawns whose body length is above 3cm were marked synchronously in eight large bays a- long the coast of Southern Shangdong. 1400 million prawns were recaptured total- ly,among them, 1184. 7tons by bottom brawl. The average recapture rate is 9. 4 per- cents. But, at the same time, 4402tons of economical juvenile fish of seven species was lost.It is time we should pay more attention to this problem. |
