The fishermen of the coast of Paraná, traditionally had in catching fish and shrimp/prawns their main form of economic income, however, the decline of small-scale fishing in the last decades, imposed on the fishing communities a new reality, where many artisanal fishermen started to devote to other activities with a more promising income, including fishing Crabs with cages. Crab fishing with cages is an economic activity that can be one of the basic elements for the development of families of fishermen living in socially vulnerable communities, however there are few or sparse information about this activity, and in particular about the effect on the retail and the relevance of this segment in the production chain of the crab caught with cages. Given this context, an exploratory study was conducted between August and November of 2015, along the 22 restaurant owners and 19 owners of fishmongers. The male gender was predominant among the managers. The origin and quality of product was attested by an absolute majority of respondents (n = 81%) as a requirement for trade in crabmeat caught with cages. Only a minority of respondents (n = 31%) reported that they sell the crabmeat caught in cages, which they consider having a superior quality compared to the one obtained with the traditional methods of shrimp dragging or landing net fishing. It was concluded that the systematics of commercialization adopted by the retail trade and crossers, negatively influence the productive chain, making the product to the final consumer more expensive and imposing low prices to the fisherman. In this context, urges the amendment of the current governance models of the productive chain of the cage crab for more collaborative models and socially fair between all links as a way of ensuring the development of the production chain.
