    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.

    Monitoramento da visitação turística em unidade de conservação marinha: aplicação de um protocolo na área de proteção ambiental costa dos corais
    (INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2025-09-26) Silva, Jaiane Nascimento da; Garcia, Lilian Vieira Miranda; http://lattes.cnpq.br/7506864164706189; Romero, Renato de Mei; https://orcid.org/0000-0001-6196-6122; http://lattes.cnpq.br/9857771457585862; Izidoro, Flávia Bonfietti; https://orcid.org/0000-0001-9421-3629; http://lattes.cnpq.br/3096072326299107; Pinheiro, Barbara Ramos; https://orcid.org/0000-0001-5032-8547; http://lattes.cnpq.br/0017521803800265
    The implementation of Conservation Units (CUs) is an important tool for protecting the planet's biodiversity, given the already advanced anthropization of natural environments. These protected territories rely on a diverse framework of protection instruments. The Costa dos Corais APA is a sustainable-use coastal-marine CU, a category that enables the development of tourism activities and the sustainable extraction of natural resources. Therefore, in addition to the creation of these areas, managing this type of use is essential for effectively achieving the objectives of this unit. As the largest coastal-marine CU in the country, one of its main conflicts of use is uncontrolled tourism in reef environments, ecosystems with low resilience and high sensitivity to anthropic actions. Therefore, the objective of this research was to develop a protocol for monitoring visitation to natural pools with tourism activities regulated by the Chico Mendes Institute for Biodiversity Conservation (ICMBio). The study was developed from an exploratory methodological perspective, and 12 indicators were developed to monitor visitation to three natural pools in the area over a five-month period. A total of 15 field visits were conducted to apply the protocol and assess environmental impacts in the area. An intense supply of supplementary food to the fauna and recurring non-compliance with the use of bathing and anchoring areas were identified. With the implementation of the monitoring protocol in the unit's management, it is expected that, in the medium and long term, it will be possible to relate the indicator results to the biological changes observed by the specific monitoring teams. Ultimately, the objective is to submit the monitoring protocol to ICMBio in the form of a Technical Technological Product, containing the results obtained, as well as a characterization of visitation and potential impacts observed.
