Thailand's marine resources are shown to be abundant, with an oversupply of blue swimming crabs in Kao Yot, Rayong Province, and the successful management of the invasive black chin tilapia in many provinces. This demonstrates the country's food security and environmental management capabilities. The control of black chin tilapia has stimulated economic opportunities, such as the production of various fish-based products and the use of the fish for feeding other animals. This initiative has been achieved through collaboration among government, private, and community sectors, showcasing a successful model of environmental management and sustainable food security.
