In the article, researchers explore ecosystem-based fishery management. They examine various concepts and models to understand ecosystems and how to manage fisheries sustainably. The study shows that there is no one-size-fits-all definition for ecosystem-based fishery management. They highlight the importance of nutrient flow in ecosystems, suggesting that nutrients act as a key element in ecological economic models for sustainable fishery management. The findings indicate a general agreement among experts on the crucial need to implement ecosystem-based approaches in fisheries management, even though there is no consistent way of applying these concepts across different ecosystems.
