This study aimed to carry out a diagnosis of the catching and of the processing of aratu meat, called “catado,” and to propose improvements for its processing. This fishing resource, important for the fishing communities in the Brazilian Northeast, generates employment and income for many artisanal fisherwomen (marisqueiras). Yet, the production of “catado” is carried out in a rudimentary way, as for instance in comunidade Preguiça (a municipality of Indiaroba), a typical fishing community on the Sergipe coast. Therefore, a survey was carried out for the preparation of a participatory diagnosis in order to identify the stages of the process, from the preparation of the marisqueiras for the capture to the realization of the "catado," and the problems related to the processing that compromise the end product quality. Some steps were proposed, such as improving hygiene during the preparation and the use of vacuum packaging, with its own logo, in order to identify the “catado” of aratu processed in that community.
Mangrove crab Goniopsis cruentata purple mangrove crab Goniopsis cruentata catching is intensive and has a great impact on the population structure. The present study aimed to present information on the population structure of aratu. The catching was carried out by a professional fisherwoman using a fishing rod with a line and bait, capturing specimens of all sizes –not only those that could be sold. The results indicated that males and females showed no difference in carapace width. Comparing average weights, males were heavier than females. Among the 448 captured females, 88% were ovigera females with a tendency to decrease between February and April and then increase. The dimension of males and females regarding carapace width indicated a predominance of females in the range between 3.2 and 4.3 cm and of males in the smallest and largest ranges. The total weight/carapace width ratio for males was PT = 0.2675*LC^3.475, showing positive allometric growth, and for females PT = 0.8863*LC^2.5775, showing negative ALLOMETRIC growth. The condition factor of females was higher (approximately 1.5 times) than that of males. Data collection took place in a short period, further research is therefore required.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
