    This dissertation presents two chapters that include environmental assessment methods applied in the hydrographic basins of the Mundaú-Manguaba Estuarine-Lagoon Complex – MMELC. Degradation in CELMM has considerable environmental and socioeconomic impacts on riverside communities. We discuss how environmental, physical and spatial changes are related to chemical descriptors and the ecological response of the ichthyofauna of streams inserted in the system, aiming to test environmental diagnostic instruments for monitoring and managing impacts on rivers and coastal streams. Chapter I presents the application of the Habitat Integrity Index, a local physical assessment (80 m) already consolidated, and two proposals, one for adapting an index for landscape (1.6 km) and another for an index integrated to the two scales to equalize possible distortions. To understand the biological responses to the index values, two ecological estimators were evaluated species richness and percentage of Poecilia reticulata, in the fish community. The results are discussed in order to evaluate the ability to describe the indexes and estimators for local physical, spatial and biological characteristics. In Chapter II, the physical and chemical descriptors of the stream and ecotone were integrated with ecological descriptors. We tested the application of the Abundance and Biomass Curves (ABC) and the W statistic in the biological evaluation to detect environmental disturbance in the streams. The indicator species analysis (IndVal) was used to describe the species that characterize each land use and occupation group, and the Redundancy Analysis (RDA) was performed to identify the chemical and physical descriptors that structure the fish communities for each land use and occupation. In general, the evaluation methodologies used were able to describe the differences in the environments for each land use and occupation and relate the physical and chemical structuring of the streams to the fish community.

    Caracterização do recinto de aclimatação marinho para peixes-bois (Trichechus manatus manatus) no Ceará : uma inovação tecnológica para o manejo da espécie no Brasil
    (INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2025-01-23) Bezerra, Brunno Torres de Gouveia; Normande, Iran Campello; Romero, Renato de Mei; https://orcid.org/0000-0001-6196-6122; http://lattes.cnpq.br/9857771457585862; Choi, Katherine Fiedler; Marques, Sheyla Karolina Justino
    For many years, the West Indian manatee (Trichechus manatus manatus) was classified as Critically Endangered in Brazil and recognized as the most vulnerable aquatic mammal in the country. To support its conservation, strategic actions such as rescue, rehabilitation, and release of manatees into the wild have been carried out since 1994 in northeastern Brazil, with the aim of repopulating areas of historical occurrence, reconnecting isolated populations, and strengthening existing population nuclei. As part of these strategies, the Association for Research and Preservation of Aquatic Ecosystems (Aquasis) implemented, in 2020, a new model of a marine acclimatization enclosure in Icapuí, Ceará, pioneering as the only structure of its kind located in a marine environment in Brazil. Consisting of a floating platform with a net-tank system, the enclosure was developed to initiate the acclimatization and release process of manatees rescued and rehabilitated by Aquasis in the state of Ceará, as part of conservation strategies for the species. In 2024, the structure of the acclimatization enclosure was expanded with the installation of a surrounding fence, forming a polygonal contour area resembling a traditional fish corral, encircling the floating platform throughout the perimeter of the polygon. This study aims to characterize the marine acclimatization enclosure used for manatee adaptation in Icapuí, Ceará, as well as to analyze other existing acclimatization enclosures in Brazil. The research compares different manatee acclimatization systems used in the country, detailing their construction features—including the floating platform and fence—describing feeding management practices, capture and handling methodologies, developing a schematic representation of the acclimatization enclosure, and proposing improvements aimed at enhancing animal welfare. The implementation of the marine acclimatization enclosure represents an innovative and strategically important structure for manatee conservation, highlighting its operational features. The results underscore the Icapuí marine acclimatization enclosure as an innovative and replicable model with the potential to expand the positive impact on species conservation.

    Diagnóstico e monitoramento da pesca artesanal marítima na RESEX da Lagoa do Jequiá : integração do conhecimento ecológico local e tecnologias de rastreamento
    (2025-01-22) Rodrigues, Diego Alexandre Salgueiro; Romero, Renato de Mei; http://lattes.cnpq.br/9857771457585862; Araujo, Daniel de Magalhães; http://lattes.cnpq.br/5837261784524743; Sampaio, Cláudio Luis Santos; http://lattes.cnpq.br/2526336992077506; Normande, Iran Campello; http://lattes.cnpq.br/7987532975778534
    The study addresses artisanal fishing in the Marine Extractive Reserve (RESEX) of Lagoa do Jequiá, highlighting the role of fishers' ethnoecological knowledge and the use of technologies to track fishing activities. The research combined semi-structured interviews, GPS tracking, and fleet counting via drones to understand fishing strategies, spatial patterns, and fishers' perceptions of environmental changes. Six fishing methods and 54 captured species were identified, revealing a strong relationship between the techniques used and the characteristics of the exploited areas. The results indicate that fishing activity is in decline, partly due to the aging fishing population and a lack of infrastructure and government support. The study also suggests that, although no tracked vessels operated within the RESEX, there are indications of fishing in protected areas during the dry season, a hypothesis that requires further investigation. Integrating local knowledge with spatial data is essential for planning marine protected areas, promoting sustainable management, and reducing conflicts between conservation and artisanal fishing.
