| 摘 要： | 应用“剩余产量模式”研究了鄱阳湖三角帆蚌和褶纹冠蚌资源,采用PC-1500型微机计算,结果表明,其最大持续产量(MSY)为6516t,比历史上最高产的1980年还高出17.7%,增产潜力大,其相应努力量为2000艘标准渔船.本文还报道了鄱阳湖46种蚌的名录,并简述了其开发利用的初步意见.

| Abstract: | Resources of Hyriopsis cumingii (Lea) and Cristaria plicata (Leach.) in Poyang Lake was discussed as SYM ( Surplus Yield Model ) applied. Using the micro-computer of PC-1500 type the Maximum Sustained Yield ( MSY ) could be 6516 tons, i.e. 10.7-17.7% percent higher than the highest yield (1979-1980 ) in the history. The relevant fishing power could be 2000 standard fishing-boat. There are fourty six species of vainidae in the Poyang Lake. Many practical methods for utilization of this abundant resource were proposed. |
