  • Shift to aquaculture urged to restore marine resources

The marine resources in Myanmar’s waters have significantly declined compared to 30 years ago. As a timely response to the shortage of fishery products, it has become necessary to focus more on aquaculture rather than capture fisheries in order to restore marine resources, according to the Myanmar Fisheries Federation.
Surveys conducted in 2013, 2015, and 2018 showed that about 90 per cent of surface fish resources and 60 per cent of underwater fish resources remained in Myanmar waters, whereas in 2022, only about 30 per cent of both surface and underwater fish resources were left. These declines are mainly attributed to two key factors: overexploitation of fishery resources and marine pollution.
About 80 per cent of marine pollution originates from land-based and coastal activities, including waste disposal such as garbage, plastics, foam, single-use items, agricultural fertilizers, industrial wastewater, urban sewage, and other pollutants. According to reports by the Norwegian research organization NIVA (2011 and later), marine pollution can be significantly reduced through systematic and effective management.
“Globally, countries are reducing the fish resources and implementing aquaculture. They are also exploring what species can be farmed and produced. In our country, aquaculture already exists, but there are still requirements to be fulfilled. Research is needed to determine how much aquaculture can increase marine resources. If we continue extracting natural resources while they are becoming scarce, it could lead to extinction. As both surface and underwater fish are declining, it is necessary to improve fish and shrimp farming. Both freshwater and marine aquaculture should be developed. Balanced efforts are also needed to replenish declining marine resources. If marine conservation and aquaculture are implemented in harmony, marine fish resources will eventually recover,” said Dr Toe Nanda Tin, senior vice president of the Myanmar Fisheries Federation.
Myanmar is a country rich in fishery resources. According to 2022 data, it ranks 14th globally in fishery resource ownership and has the highest freshwater fish production in Southeast Asia. Marine resources in Myanmar can recover within a decade through reducing pollution, protecting coral reefs, controlling overfishing, and expanding freshwater and saltwater aquaculture zones. — Thitsa (MNA)/KTZH
