The paper summarizes the methods and results of a three years socio-economic study (2015–2017) on the bottom trawl fleet targeting Deep water rose shrimp (Parapenaeus longirostris) and European hake (Merluccius merluccius) in North Tunisia. Socio-economic data collected were processed to estimate 25 indicators related to employment, activity, demographics and economic performance of the fishery. The indicators estimated highlighted both the profitability and fragility of this fishery, which strongly relies on the product demand from the international market. During the three years of study, the economic profits have been positive for the target fishery. Indicators of demographics and employment describe a well-performing fishery, close to international standards and with further margins for improvement. The number of fishers employed on board (on average 11 fishers per vessel), the age of the fishing fleet (an average age of 45 years) and the number of fishing units accessing the fisheries (strongly related to the size of the migrant fleet) are among the main factors characterizing the fishery and undermining its stabilization and further development. This first appraisal of its main socio-economic characteristics could be part of the baseline information needed by policy makers to ensure environmental, social and economic sustainability to bottom trawl fishery in North Tunisia. The study is also an opportunity for testing the approach proposed by the FAO as a standard procedure for socio-economic studies on Mediterranean fisheries.

本文总结了针对深水玫瑰虾 ( Parapenaeus longirostris ) 和欧洲无须鳕 ( Merluccius merluccius ) 的底拖网船队为期三年的社会经济研究 (2015-2017) 的方法和结果) 在突尼斯北部。对收集的社会经济数据进行处理，以估计与渔业就业、活动、人口统计和经济绩效相关的 25 项指标。估计的指标突出了该渔业的盈利能力和脆弱性，该渔业在很大程度上依赖于国际市场的产品需求。在三年的研究中，目标渔业的经济利润一直是正的。人口统计和就业指标描述了渔业表现良好，接近国际标准，还有进一步改进的余地。船上雇用的渔民人数（每艘船平均 11 名渔民），捕捞船队的年龄（平均年龄为 45 岁）和进入渔业的捕捞单位数量（与移民船队的规模密切相关）是渔业的主要特征，并破坏了其稳定和进一步发展。对其主要社会经济特征的首次评估可能是决策者所需的基线信息的一部分，以确保突尼斯北部底拖网渔业的环境、社会和经济可持续性。该研究也是一个机会，可以测试粮农组织提出的作为地中海渔业社会经济研究标准程序的方法。对其主要社会经济特征的首次评估可能是决策者所需的基线信息的一部分，以确保突尼斯北部底拖网渔业的环境、社会和经济可持续性。该研究也是一个机会，可以测试粮农组织提出的作为地中海渔业社会经济研究标准程序的方法。对其主要社会经济特征的首次评估可能是决策者所需的基线信息的一部分，以确保突尼斯北部底拖网渔业的环境、社会和经济可持续性。该研究也是一个机会，可以测试粮农组织提出的作为地中海渔业社会经济研究标准程序的方法。
