After agreeing on a settlement in a lawsuit against the owners of the Chinese land-based shrimp 'megafarm', Sino Agro Food, shareholders are now looking to reverse the decline in the company's fortunes.

"We invested in Sino Agro Food because we saw a significant opportunity for aquaculture in China," said Peter Halesworth, manager of the Heng Ren funds, which brought the lawsuit against the company last year.
