Over the past three decades, the global aquaculture industry has risen from obscurity to become a critical source of food for millions of people. In 1990, only 13 percent of world seafood consumption was farmed; by 2014, aquaculture was providing more than half of the fish consumed directly by human beings.

The boom has made farmed fish like shrimp, tilapia and pangasius catfish – imported from countries such as Thailand, China and Vietnam – an increasingly common sight in European and North American supermarkets. As a result, much research on aquaculture has emphasized production for export.

Focus - Scholars - Aquaculture - Contributes - Food

This focus has led scholars to question whether aquaculture contributes to the food security of poorer people in producing countries. Many have concluded it does not. Meanwhile, the industry's advocates often emphasize the potential for small-scale farms, mainly growing fish for home consumption, to feed the poor. Farms of this kind are sometimes claimed to account for 70 to 80 percentof global aquaculture production.

Our research shows that both of these perspectives are wildly out of sync with current developments. In fact, the vast majority of farmed fish is consumed in the same developing countries where it is produced, and is widely accessible to poorer consumers in these markets. Most of it comes from a dynamic new class of small- and medium-scale commercial farms, the existence of which is rarely recognized. To understand the potential of aquaculture to feed the world, researchers and consumers need to appreciate how dynamic this industry is.

Fish - Source - Vitamins - Minerals - Acids

Fish is a rich source of vitamins, minerals, essential fatty acids and high-quality protein. It plays a particularly important role in the diets of billions of consumers in low- and middle-income countries. Many of these people are poor, malnourished and unable to afford alternative nutrient-rich foods such as fruit, eggs and meat.
