Over fishing occurs when more fish are caught than the population can replace through natural reproduction. Results of over fishing not only affect the balance of life in the oceans, but also the social and economic well-being of the coastal communities who depend on fish for their way of life. More than 85 percent of the world's fisheries have been pushed to or beyond their biological limits and are in need of strict management plans to restore them. pirate fishing and other regulatory problems.
Causes of overfishing are due to lack of protection, Just 1.6% of the world's oceans have been declared as marine protected areas (MPAs), and 90% of existing MPAs are open to fishing. Targeted fishing of top predators such as sharks and tuna eventually disrupt marine communities, causing increased abundance of smaller marine animals at the bottom of the food chain. Coastal communities around the world depend on fish as their primary source of protein. Overfishing threatens their long-term food security, particularly in developing countries
