More than 25 major seafood buyers are urging the governments of China, India, Indonesia, Thailand and Vietnam to take “increased and immediate action” in addressing continued outbreaks and emergence of new diseases in Asian shrimp farms.

The buyers sent a letter to the governments of these five countries which are the world’s top producers of shrimp.

“Governments need to take action now to stop disease outbreaks in shrimp farms,” said Anton Immink, aquaculture director at the Sustainable Fisheries Partnership (SFP).
