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.
