Fish stocks around the world are crucial for food supply, especially for the poorest communities. Studies show that overfishing is a growing issue, leading to concerns about declining fish populations. Research on assessed stocks reveals that proper fisheries management leads to increasing abundance and reaching target levels. Regions with less management have higher harvest rates and lower abundance. Areas without abundance assessments lack proper management and have struggling fish stocks. To sustain fisheries, it is essential to apply appropriate science-based management in all regions.
