Fisheries management is the specialized skill of regulating and maintaining sustainable fish populations in bodies of water. This includes monitoring fish populations, setting catch limits, and implementing conservation measures to ensure the long-term health and viability of aquatic ecosystems. Fisheries managers work closely with scientists, policymakers, and other stakeholders to make informed decisions based on data analysis and research. Effective fisheries management is crucial for preserving biodiversity, supporting livelihoods, and providing food security for people around the world.
