Sustainable fishing practices are crucial for marine conservation, as they help maintain biodiversity and ensure the health of fish populations. Overfishing can lead to the collapse of vital species, disrupting ecosystem balance and threatening the livelihoods of communities dependent on fishing. By implementing regulations like size limits and catch quotas, sustainable practices promote resilience in marine environments. These efforts also enhance food security and contribute to the overall sustainability of ocean resources. Ultimately, sustainable fishing supports both ecological health and the long-term viability of the fishing industry.
