The objective of this study is to analyze the value chain of Ucides cordatus along mangroves of the Parnaíba Delta, investigating the activities that add value to the crustaceans, the institutional arrangement for management and governance, and the profit margin of the chain based on the standardization of storage and transportation of crabs. The case study took place in 15 supply areas within conservation units in the Parnaíba River Delta. Three workshops were held in each area between September 2015 and October 2016, totaling 45 workshops in which 265 actors (crabbers, community intermediaries, and crabmeat processors) participated. Participant observation, informal conversations and interviews with 140 stakeholders of the value chain were also carried out. Value-adding activities in the crab extraction, marketing, crabmeat processing, transportation and consumption segments are described. The regulation of the storage and transportation of crabs and the institutional structure of the chain led to a set of improvements and innovations in extraction and commercialization processes, and also reduced waste. The value chain of U. cordatus is poorly studied, and thus the present study contributes to its understanding as a managerial tool for fisheries, and to the view of the normative instruction as a regional policy for the conservation of crustaceans in the Parnaíba Delta.

红树林蟹 ( Ucides cordatus ) 的价值链:巴西东北部 Parnaíba 三角洲的案例研究

本研究的目的是分析Ucides cordatus的价值链沿着 Parnaíba 三角洲的红树林,调查为甲壳类动物增值的活动,管理和治理的制度安排,以及基于螃蟹储运标准化的链条的利润率。案例研究在 Parnaíba 河三角洲保护区内的 15 个供应区进行。2015 年 9 月至 2016 年 10 月期间,每个地区举办了 3 场研讨会,共计 45 场研讨会,265 名参与者(螃蟹、社区中介和蟹肉加工商)参加。还对价值链的 140 名利益相关者进行了参与者观察、非正式对话和访谈。描述了蟹提取、营销、蟹肉加工、运输和消费领域的增值活动。对螃蟹储运的监管和链条的制度结构导致了提取和商业化过程的一系列改进和创新,也减少了浪费。价值链U. cordatus的研究很少,因此本研究有助于将其理解为渔业管理工具,并有助于将规范性教学视为保护帕纳伊巴三角洲甲壳类动物的区域政策。
