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

In Côte d'Ivoire, fish farming is seen as a supplement to fish production. A more efficient use of resources in the production process would assure sustainable fish production. Using a data envelopment analysis (DEA) model and cost-benefit analysis, this study examines the resource efficiency and economic efficiency of 32 fish farms in the southeast of Côte d'Ivoire. 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. The most technically and economically efficient fish farmers use industrial feed. The study found that fish farmers caused excesses in resource utilization, resulting in a shortfall in output utilizing DEA model scenarios. Scenario-3, based on the slack-based model, minimizing resources while maximizing output, revealed that reducing resource excesses would have increased output by 16.18%. Based on the cost-benefit analysis, fish farms produced a positive gross and net profit margin. According to the findings of this study, policymakers should play a significant role in improving fish farmers' access to quality feed and fingerlings. Furthermore, fish farmers must be trained in sustainable production and pond management procedures.
