Tra Vinh province in Vietnam, which has a snakehead fish farming area of 537 hectares, is facing challenges as the domestic market for the fish is shrinking and prices are decreasing. The industry is also struggling with increasing production costs and oversupply due to the expansion of fish farming areas. The local authorities are advising farmers to diversify their breeds to avoid oversupply and environmental risks, as the current supply exceeds demand and Tra Vinh's snakehead fish does not have a brand for official exports.
