None of the four models could work well in the scenario 2, under explored stock, however they got accurate results in scenario 1, regulated stock. The Schnute model work well in full explored stocks such as scenario 1, 3, 4 and 5, especially in low biomass stocks such as scenario 3, but not suitable to the under explored stocks such as scenario 2. The W-H model generally performed well in all kind of scenarios especially in scenario 1, 4, and 5. In the swordfish, xiphias gladius, fishery, estimation of W-H model and D-Fox model produced MSY about 14000 ton, very near the result of Prager in 1996.The author tentatively explored the suitable fishing condition for the models to stock assessment.
四种剩余产量模型在充分捕捞且管理良好的渔业1中评估效果较好而在捕捞不足的渔业2中效果较差;Schnute模型在充分捕捞的渔业如渔业1、3、4、5、尤其是在低生物量的渔业3中评估效果较好,但不适合评估未充分捕捞的渔业,如渔业2;Walters-Hilborn模型适用于各种渔业,尤其是渔业1、4、5;在过度捕捞渔业中如渔业3、4,模型对参数q的估计较其它参数接近真值;在北大西洋箭鱼渔业的评估中,W-H模型和D-Fox模型对MSY的估计约为14000吨,接近于Prager(1996)的结果。
