Resource Efficiency and Economic Efficiency of Fish Farms in the Southeast of Côte d’Ivoire

Abstract

Abstract Fish farming is considered a complement to fish production in Côte d’Ivoire. Better use of resources in the production process would ensure sustainable fish production. This study analyzes the resource efficiency and economic efficiency of 32 fish farms in the southeast of Côte d’Ivoire using a data envelopment analysis (DEA) model and cost-benefit analysis. The results revealed that fish farmers showed low performance, with average technical efficiency scores of 0.738 (CRS) and 0.575 (SBM) and an average economic score of 0.553. Fish farmers using industrial feed are the most technically and economically efficient. Through DEA model scenarios, the study shows that fish farmers generated excesses in resource utilization, causing a shortfall in output. Scenario-3 based on the slack-based model minimizing resources simultaneously with a maximization of output indicated that a reduction of excesses in resources would have increased the output by 16.18%. Finally, the cost benefit analysis shows that, overall, fish farms achieved a positive gross and net profit margin. This study suggests that policy actors should play an important role in facilitating fish farmers’ access to feed and quality fingerlings. In addition, fish farmers must be trained on good practices for sustainable production and pond management.
