Sustainable and accessible fish feeds for small-scale fish farmers

Abstract

Improving feed accessibility for small-scale fish farmers is crucial to the inclusive growth of aquaculture. “Nutritious pond feeds” nourish the farmed fish and the pond organisms that help break down fish wastes and produce natural food for the fish. Their ingredient composition makes them less expensive than conventional feeds while maintaining or increasing fish production in a healthy pond environment. Local, underused and inexpensive agricultural co-products can be effectively used as fish feed ingredients, thereby reducing dependency on ingredients that can be directly consumed by humans. The FeedCalculator mobile phone application equips small-scale feed millers and farmers to formulate nutritious pond feeds from local ingredients.
