WorldFish is an international, nonprofit research organization that harnesses the potential of fisheries and aquaculture to reduce hunger and poverty. Our publications database contains WorldFish publications and references to WorldFish research published in refereed journals and periodicals.
Fish is a widely available animal-source food in Bangladesh and a rich source of nutrients, yet little is known about practices related to incorporating fish into the diets of infants and young children. Our study makes use of dietary diversity data collected from households participating in a homestead aquaculture project in rural Bangladesh, a population that we hypothesized would have greater than average access to fish.
This study shows people in Bangladesh are now eating 30% more fish than they did 20 years ago, but they are getting a smaller amount of important nutrients from it. The results challenge the conventional narrative that increases in food supply lead to improvements in diet and nutrition. As aquaculture becomes an increasingly important food source, it must embrace a nutrition-sensitive approach, moving beyond maximising productivity to also consider nutritional quality.
