Malaysia’s sea bass industry is collapsing as Thailand tightened inspections on June 1, 2026, effectively blocking shipments that once totaled 80 tonnes daily. The farms in Sungai Udang supplied 80.6% of Malaysia’s RM115 million (S$36.5 million) sea bass exports to Thailand in 2024. Farmers now borrow money to feed idle fish while awaiting test results that can take 20 days, by which time the catch spoils.

How the Thai ban strangled Malaysian exports

For years, lorries rolled daily from Sungai Udang in Penang carrying sea bass to Thailand, about 16 truckloads totaling 80 tonnes. That trade stopped completely after Thai authorities began subjecting Malaysian shipments to stricter laboratory testing over alleged chemical and antibiotic residues. Farmers deny the claims. Shipments are held until results arrive, a process that takes up to 20 days. By then the fish have spoilt and become unsaleable.

The financial squeeze on 200 farms

About 200 sea bass farms operate across northern Malaysia, with CS Fishery among the largest at over 80 hectares and 200 workers. Director Khor Kok Hooi, who chairs the North Malaysia Aquaculture Entrepreneur Society, said “Our sea bass industry is dying.” Some farms have already folded. Others switched to tilapia or prawns to survive. Farms still feeding idle sea bass face drying cash flow with no revenue coming in.

Farmers call it a trade barrier, not a safety measure

Malaysian exporters and officials say tighter scrutiny began in November 2024, but the issue gained public attention in May 2026. Khor called the inspections “a form of trade barrier that restricts Malaysian sea bass from entering the Thai market.” If any violations are found during testing, the exporter faces fines. The 20-day delay makes compliance impossible for a perishable product.

Broader fisheries tensions ease as both nations seek cooperation

Malaysia and Thailand have moved toward settling long-running fisheries disagreements and jointly pursuing special border economic zones. This represents a strategic shift toward using economic cooperation to strengthen bilateral relations and improve border governance. The agreement links conflict resolution with economic opportunity, positioning border regions as engines of growth through improved infrastructure and trade facilitation rather than focusing solely on dispute management.

Final Thoughts

Malaysia’s sea bass farmers face an existential crisis as Thailand’s June 2026 inspections block their largest market. With 80% of exports frozen and 200 farms struggling, the sector needs urgent diplomatic resolution or faces permanent collapse.
