Abstract: Although many small-scale fish farming projects around the world promote fish production as a source of low-cost protein, increasing evidence demonstrates fish to be an important cash crop, even for limited-resource farmers. A mathematical programming model was developed from survey data of Rwandan farmers to determine optimal resource allocation on subsistence farms in Rwanda. The specific Objectives of the study was to determine farm plans that maximize returns to a representative Rwandan farm family’s resources, subject to constraints of the farm family’s proteinic and caloric requirements. Soybeans, sweet potatoes, and maize were selected to meet household nutritional requirements. Fish production was selected as the principal cash crop, in most cases lending support to the evidence that fish is more important as a cash crop than as a primary protein source in Rwanda
