Increased aid to developing countries for sustainable fisheries could increase food security worldwide, says a recent article in the Feb. 12 issue of Science.

Still, a lack of policy coordination on the issue among nations is threatening seafood supplies, it says.

While the paper looks at trade policies and private incentives as possible options to make the seafood industry more sustainable, it concludes that increased aid for infrastructure in developing countries is the best option, since it wouldn't cause short-term problems for consumers or producers.

However, to ensure the sustainability of seafood, such as the Atlantic bluefin tuna, may require a more stringent approach — in the form of an international trade ban.

The U.N.’s Convention on International Trade in Endangered Species of Wild Fauna and Flora will vote during this month’s meeting in Doha, Qatar on implementing a ban on the tuna, reports the BBC.

"The goal is not to ban trade indefinitely, but to suspend international trade until the species recovers sufficiently to enable international trade to resume," says Sue Lieberman, director of international policy with the Pew Environment Group.
