This study examines the biological and economic sustainability of the fisheries sector in Cape Verde, with a focus on its potential contribution to the Blue Economy. The estimated fish stocks in Cape Verde range from 32,000 to 41,000 tonnes, and fresh fish represents a significant source of animal protein for the Cape Verdean population. Using the standard bioeconomic models, we analyze fishing effort and harvest data from 1993 to 2021 to determine key reference points for equilibrium, such as Effort at Maximum Sustainable Yield (), Maximum Sustainable Yield (MSY), Effort at Maximum Economic Yield (), Maximum Economic Yield (MEY), Effort at Open Access Equilibrium (), and Open Access Equilibrium Yield (OAY). Additionally, we apply the Input–Output model to compute the output and employment multipliers for the fisheries sector, assuming it operates at Maximum Economic Yield. Our findings indicate that in 2021, the fishing effort and harvest levels exceed those necessary for maximum sustainable yield. To ensure the biological sustainability and growth of fisheries in Cape Verde, a reduction of 17 percent in fishing effort and 9 percent in harvest is recommended. Furthermore, the results of the Input–Output model reveal an output multiplier of 1.743 and an employment multiplier of 1.265 for the fishing sector. Based on our analysis, policymakers seeking to increase the output multiplier should focus on increasing the number of industrial vessels, while promoting artisanal vessels would be more effective in achieving a higher employment multiplier.

评估蓝色经济的可持续性和潜力：佛得角渔业部门的生物经济和投入产出分析

本研究考察了佛得角渔业部门的生物和经济可持续性，重点关注其对蓝色经济的潜在贡献。佛得角的鱼类资源估计量为 32,000 至 41,000 吨，鲜鱼是佛得角人口动物蛋白的重要来源。使用标准生物经济模型，我们分析 1993 年至 2021 年的捕捞努力量和收获数据，以确定平衡的关键参考点，例如最大可持续产量的努力量 ()、最大可持续产量 (MSY)、最大经济产量的努力量 ()、最大经济收益 (MEY)、开放获取均衡的努力 () 和开放获取均衡收益 (OAY)。此外，假设渔业部门以最大经济产量运营，我们应用投入产出模型来计算渔业部门的产出和就业乘数。我们的研究结果表明，到 2021 年，捕捞努力量和收获水平超过了最大可持续产量所需的水平。为了确保佛得角渔业的生物可持续性和增长，建议减少17%的捕捞努力量和9%的收获量。此外，投入产出模型的结果显示，渔业部门的产出乘数为 1.743，就业乘数为 1.265。根据我们的分析，寻求提高产出乘数的政策制定者应重点关注增加工业船舶的数量，而推广手工船舶将更有效地实现更高的就业乘数。
