Summary:
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
