The Peruvian artisanal squid fleet accounts for more than 45% of the worldwide landings of the jumbo flying squid (JFS) fishery, the largest invertebrate fishery worldwide. Nevertheless, most vessels involved in the fishery lack secure tenure rights and operate within the informal economy. Interviews and a survey directed to shipowners allowed identification of three economic regimes under which the fleet operates and estimation of annual operating costs, revenues, and added value. Our results show that the fishery has high economic importance in Peru, accounting annually for 9–15% of the total Peruvian fisheries sector's GDP. Even during 2020, highly impacted by the COVID-19, the fishery was profitable and maintained economic accounts not substantially below of previous years. Furthermore, public data on landings and off-vessel and export prices were used to model the impact of supply on price elasticity for fishers and exporters in Peru and Chile. Data showed steep declines in off-vessel prices with increasing supply for Peruvian fishers. Conversely, Peruvian exporters and Chilean fishers and exporters mostly retained stable prices at nearly all supply levels. The paper suggests that the informal status of the Peruvian JFS fishing activity, which lacks co-management mechanisms, is amongst the co-factors explaining the different price elasticity suffered by the Peruvian fishers. In view of the results, we suggest that speeding up the granting of secure tenure rights to the acting operative artisanal fleet and prompt development of co-management arrangements has the potential to bring environmental and economic gains for fishers.

秘鲁手工鱿鱼船队占全球最大的无脊椎动物渔业——巨型飞鱿鱼 (JFS) 渔业的 45% 以上。然而，参与渔业的大多数船只缺乏安全的使用权，并且在非正规经济中运营。通过对船东的访谈和调查，可以确定船队运营的三种经济体制，并估算年度运营成本、收入和附加值。我们的结果表明渔业在秘鲁具有很高的经济重要性，每年占秘鲁渔业部门 GDP 的 9-15%。即使在 2020 年期间，受 COVID-19 的严重影响，该渔业仍是盈利的，并保持了不低于往年的经济账户。此外，上岸量、离船价格和出口价格的公共数据被用来模拟供应对秘鲁和智利渔民和出口商价格弹性的影响。数据显示，随着秘鲁渔民的供应增加，船外价格急剧下降。相反，秘鲁出口商和智利渔民和出口商几乎在所有供应水平上都保持稳定的价格。该文件表明，秘鲁 JFS 捕鱼活动的非正式地位缺乏共同管理机制，是解释秘鲁渔民遭受不同价格弹性的共同因素之一。鉴于结果，我们建议加快授予代理作业手工船队有保障的使用权并迅速制定共同管理安排有可能为渔民带来环境和经济收益。
