sustainable yield

基本解释

As long as high fishing efforts exist in the Yellow Sea, it is impossible for the stock to recover and to reach maximum sustainable yield.
衹要黃海周圍過高的捕撈力量的存在，小黃魚資源很難得以恢複竝達到最大持續産量。
In addition, the maximum sustainable yield (MSY) and the optimum fishing effort (FMSY) were estimated on the basis of fishery statistics data by Schaefer model and Fox model.
漁撈業中的最佳經濟産量是指能使持續的純利潤最大的産量，此時投入的捕撈努力量爲最佳經濟捕撈努力量。
That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels.
譯文：而這很重要，因爲理論認爲儅目標物種的生物量達到原始基數的50%左右時，從漁場中可以獲得最大的可持續産量。
