解釋
旗魚屬-
The paper compares the most popularly used surplus production models using simulated data and swordfish, xiphias gladius, fishery data in the north atlantic ocean
本文應用目前常用的四種剩餘產量模型對五種漁業條件下的漁業生物種群及北大西洋箭魚種群xiphiasgladius評估結果作了比較。 -
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
四種剩餘產量模型在充分捕撈且管理良好的漁業1中評估效果較好而在捕撈不足的漁業2中效果較差； schnute模型在充分捕撈的漁業如漁業1 、 3 、 4 、 5 、尤其是在低生物量的漁業3中評估效果較好，但不適合評估未充分捕撈的漁業，如漁業2 ； walters - hilborn模型（ w - h模型）適用於各種漁業，尤其是漁業1 、 4 、 5 ；在過度捕撈漁業中如漁業3 、 4 ，模型對參數q的估計較其它參數接近真值；在北大西洋箭魚（ xiphiasgladius ）漁業的評估中， w - h模型和d - fox模型對msy的估計約為14000噸，接近於prager （ 1996 ）的結果。
