Production and trade of wild and farmed fish (finfish and shellfish) are intertwined. While many wild fish stocks have become depleted and total global fisheries catch plateaued, aquaculture production has boomed. At the same time, the global seafood trade has grown dramatically, with a net flow of seafood from poorer to richer nations, and demand for seafood is growing worldwide. Many farmed

About 25–30% of the annual global fish catch is used for animal feed inputs, a majority now to aquaculture. Thus, growing aquaculture production can add to pressures on wild fisheries. Emerging technologies for alternative feed ingredients coupled with private sector incentives for more sustainable production may in the future loosen linkages between wild fisheries and aquaculture, although the extent of this loosening is not yet clear.A Chinese version of this article's abstract is available online at: www.informaworld.com/rglo
