    Desenvolvimento de uma peneira de baixo custo para descascar sururu

    The sururu production chain is characterized by human suffering, from fishing to packaging. It can be divided into stages: fishing or gathering, washing, despining, cooking, peeling or deshelling, bottling and marketing. The step to peel or deconch it occurs through sieving. It is carried out mainly by women and children, who are subjected to great physical effort, as it is a completely manual operation. They are exposed to terrible ergonomic conditions and receive the lowest pay in the entire production chain. In this context, mechanization and automation are seen as a viable solution to reduce human suffering and the evolution of processes and products. The objective of this work was to expose, in an organized way, the technical and intellectual productions, during the Postgraduate Program Analysis of Environmental Systems, at Centro Universitário CESMAC, to develop a prototype built with recycled or reused materials, capable of peeling sururu and reduce the pain of seafood restaurants. This prototype for sifting sururu should improve the quality of life of workers involved in this production chain. The reduction of physical efforts resulting from its use should also reduce the emergence and incidence of muscle injuries and injuries. For its construction, experimental research was initiated, which included a literature review, patent prior research and the use of tools and software for projection, modeling and manufacturing. The prototype consists of a perforated and rotating basket, through which the molluscs fall and the shells are retained inside. As for its operation, when activated, an electric motor on the prototype produces the rotational movement of the perforated basket and the sururus that pass through the holes fall onto a tray placed at the base of the equipment. After completing the operation, the sururus must be collected and the shells must be discarded or reused appropriately. The research was carried out at the Shared Innovation and Technology Laboratory (Colab), of the Federal Institute of Education, Science and Technology of Alagoas (IFAL), Campus Maceió, with support from projects promoted by technological innovation notices, in addition to partnerships with institutions, non-governmental organizations and cooperatives. It begins the transition to the manufacturing process and should be expanded to generate new products, with the aim of serving other activities in the sururu production chain. Currently, research on the ergonomic impacts in the sieving stage is being developed, through which it will be possible to evaluate the benefits of using the prototype. And research to carry out tests with the purpose of establishing optimal operational parameters must be carried out.

    Pesca, comércio e conservação de Elasmobrânquios : um estudo de caso no nordeste do Brasil
    (INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2025-11-28) Santos, Erik Antonio Ferreira dos; Sampaio, Cláudio Luis Santos; https://orcid.org/0000-0002-0389-2302; http://lattes.cnpq.br/2526336992077506; Romero, Renato de Mei; https://orcid.org/0000-0001-6196-6122; http://lattes.cnpq.br/9857771457585862; Melo, Joabe Gomes de; http://lattes.cnpq.br/5180399418500159; Ferreira, Cristiane de Paula; http://lattes.cnpq.br/7804816854015308
    Sharks and rays, comprising 96% of cartilaginous fish, are crucial for regulating coastal and oceanic food webs, yet they constitute the most threatened group of marine vertebrates, with 53 species at risk in Brazil, with fishing being the main threat factor. In view of this problem, the present study aims to analyze the socioeconomic and ecological aspects related to the fishing and trade of elasmobranchs carried out in the traditional fishing community of Jaraguá (Maceió - Alagoas). Bibliographic and documentary research was conducted in a literature review process, in addition to interviews using structured and semi-structured questionnaires. As results, 18 fishermen from the community were interviewed, a completely male public, and through their reports and documentary records, the presence of several endangered species was identified, captured by gillnet fishing and handline, but caught predominantly incidentally and as bycatch of other fishery resources, representing a fishery of low economic significance. The fishermen demonstrated knowledge of the environmental legislation regarding the protection of elasmobranchs, especially the prohibition of the fin trade, which they claimed no longer occurs, but alleged ignorance of the ecological importance of the animals. Therefore, it is considered that elasmobranchs are not targets of directed fishing by the Jaraguá fleet; however, an educational process is necessary to mitigate the existing fishing of species protected by law, both for the protection of the animals and to prevent legal sanctions for the workers.
