The world's shrimp farmers are not making needed improvements in sustainable production, according to a new report from Sustainable Fisheries Partnership (SFP).

"There are significant, ongoing sustainability concerns across all major farmed shrimp production regions, particularly in China," SFP said Wednesday.

The report is a companion to the upcoming 2018 shrimp sector report relating to SFP’s Target 75 Initiative, a global movement launched last year that sets the goal of seeing 75 percent of the world’s seafood production in key seafood sectors operating sustainably or improving toward sustainable production by the close of 2020.
