China's agriculture ministry granted FeedKind full approval for fish and shrimp feeds after an extensive evaluation, opening the world's largest aquafeed market to the protein made by Calysseo in Chongqing. The process was pioneered by Statoil and developed by Calysta in Teesside, UK.

## Key facts

- China's aquafeed market was 16.9 million t in 2023

- A 100,000 t plant in Saudi Arabia was hoped for by end-2026, pending construction and approvals
