The acquisition of Chinese tilapia giant Baiyang Industry Investment Group by the state-owned conglomerate set to host this year's China Fisheries and Seafood Show involves transferral of a CNY 987.3 million ($138.3 million/€124.4 million) stake in the company, new documents posted to the Shenzhen Stock Exchange have revealed.

A "strategic cooperation agreement" was signed between Baiyang and Qingdao-based Guoxin Blue Silicon Valley Development in February in order to build a "bigger and stronger" marine industry, the companies said at the time.
