SINGAPORE — Even as global food prices hit record levels, rising in January for the seventh month in a row amid concerns about future shortages, fish farming is a bright spot in the generally challenging outlook for food production. This is why Japan and many other Asian countries are so interested in aquaculture.

In the past, most fish have been caught in the wild. However, in recent decades, a rapidly growing volume and range of fish have been raised in tanks and ponds on land, or in cages and nets in oceans, lakes and rivers, helping to meet growing demand for protein. Aquaculture is now a $100 billion industry.

Asia has led the way in production and exports of both wild capture and farmed fish, making an increasingly important contribution to the region's food security, while providing expanded employment opportunities and alleviating poverty.
