The theory of maximum sustainable yield (MSY) underpins many fishery management regimes and is applied principally as a single species concept. Using a simple dynamic biomass production model we show that MSY can be identified from a long time series of multi-stock data at a regional scale in the presence of species interactions and environmental change. It suggests that MSY is robust and calculable in a multispecies environment, offering a realistic reference point for fishery management. Furthermore, the demonstration of the existence of MSY shows that it is more than a purely theoretical concept. There has been an improvement in the status of stocks in the Northeast Atlantic, but our analysis suggests further reductions in fishing effort would improve long-term yields.
最大持续产量（MSY）理论是许多渔业管理体制的基础，主要作为单一物种概念来应用。我们使用一个简单的动态生物量生产模型表明，在存在物种相互作用和环境变化的情况下，可以从区域尺度的多鱼种长期数据系列中确定 MSY。这表明 MSY 在多物种环境中是稳健且可计算的，为渔业管理提供了一个现实的参考点。此外，MSY 的存在证明表明它不仅仅是一个纯粹的理论概念。东北大西洋的鱼类资源状况已经有所改善，但我们的分析表明，进一步减少捕捞努力将提高长期产量。
