摘　　要：应用营养动态模式和Cushing模式估算台湾海峡及其邻近海域渔业资源生产力分别为 3 0 6.0 9× 10 4t和3 0 3 .84× 10 4t;Gulland和最大持续产量Yms简单模式估算该海域的最大持续产量分别为 15 5 .0 6× 10 4t和 15 2 .4 9× 10 4t ;Schaefer和Fox剩余产量模式估算其最大持续产量分别为 187.0 8× 10 4t和 15 7.89× 10 4t,扣除非可捕群体后 ,实际为 15 9.0 2× 10 4t和 13 4 .2 1× 10 4t;估算以 1996年福建动力拖网渔船单位kW渔捞效率为标准的最适捕捞力量分别为 168.0 4× 10 4kW和 199.4 4× 10 4kW。Using trophic dynamic model and Cushing model, the annual productivity of fishery resources in Taiwan Strait and its adjacent waters, 22°00′-27°10′N,117°30′-126°30′, are estimated to be 306.09×10 4 t and 303.84×10 4 t, respectively.The maximum sustainable yields(Y ms ) are calculated using Gulland model and the simple model (Y ms =0.5B) to be 155.06×10 4 t and 152.49×10 4, respectively. The Y ms are estimated using Schaefer model and Fox surplus yield model to be 187.08×10 4 t and 157.89×10 4 t, and the actual maximum sustainable yield (deducting a part of young fish) are 159.02×10 4 t and 134.21×10 4 t;the optimum fishing efforts are 168.04×10 4 kW and 199.44×10 4 kW on the basis of fishing rate of per kW of power trawler in Fujian 1996. But the real yield and fishing efforts are 209.07×10 4 t and 361.03×10 4 kW in 1996. They are both over the theoretical Y ms and f MSY .
