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.
只要黄海周围过高的捕捞力量的存在，小黄鱼资源很难得以恢复并达到最大持续产量。
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.
渔捞业中的最佳经济产量是指能使持续的纯利润最大的产量，此时投入的捕捞努力量为最佳经济捕捞努力量。
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.
译文：而这很重要，因为理论认为当目标物种的生物量达到原始基数的50%左右时，从渔场中可以获得最大的可持续产量。
