“…Essa afirmativa é corroborada com a exposição de que, no litoral baiano, "[...] a produção pesqueira marinha extrativa é oriunda predominantemente ou exclusivamente da pesca artesanal" (SOARES et al, 2009, p. 161). Por assemelhar-se à economia de subsistência, na qual parte da produção é consumida pelos próprios produtores, e por Nas atividades da pesquisa--ação foi possível captar a percepção dos pescadores do Litoral Sul quanto ao declínio dos estoques pesqueiros do território possuir considerável nível de informalidade, esse tipo de pesca gera dificuldade em relação à coleta de dados (SOARES et al, 2009). Conforme ficou comprovado pela pesquisa-ação realizada entre 2010 e 2016, parte da produção, na época, era comercializada localmente e parte consumida pelos próprios pescadores, sem processo oficial de registro, abrindo espaço para dados inconsistentes.…”

O ritmo de utilização dos oceanos pelo ser humano está a ser muito superior ao compasso dos consensos que a humanidade está a conseguir atingir em fóruns internacionais. Esta divergência está a colocar os oceanos numa rota perigosa que pode gerar excessivas tensões ambientais, sociais e económicas, de consequências imprevisíveis. Alguns sinais de uso desmedido já se conseguem identificar claramente, em “ilhas” de plástico que existem em todos os oceanos e nos extremos índices de poluição costeira, identificados nos oceanos Pacífico e Índico asiáticos, bem como no Golfo da Guiné e em partes do Oceano Pacífico na América Central. Utilizando os mecanismos que levaram à criação das agências vocacionadas para o espaço, os países que mais utilizam os oceanos devem ponderar a criação ou upgrade de agências nacionais para o desenvolvimento sustentável através dos oceanos, mares, lagos e rios. Palavras-chave: Economia azul. Oceano. Infraestrutura socioeconómica. Desenvolvimento sustentável.

“…Copper can be found in association with different fractions, depending on geochemical conditions and the factors that control its speciation processes under conditions of higher or lower availability to the biota (Otero et al, 2000a;Chakraborty et al, 2015). Among the shellfish species extracted in the BTS, the crab Ucides cordatus is one of the main crustaceans exploited in this region (Soares et al, 2009;Mota et al, 2023) and one of the most consumed throughout the country (Pinheiro et al, 2016). It is considered a bioindicator of pollution in mangroves, as it bioaccumulates both organic pollutants and trace elements in its tissues (Nudi et al, 2007;Almeida et al, 2014;Silva et al, 2018;Ramos and Leite, 2022).…”

Crab and soil samples were seasonally collected at four mangrove sites (Cacha Prego, CP; Ponta Grossa, PG; Ilha de Maré, IM; and Pitinga, PT) in Todos os Santos Bay, in NE Brazil. Total Cu levels in soils ranged from 2.5 to 89.4 mg kg−1, while in crab organs (muscles, hepatopancreas, and gills), Cu ranged from 20 to 1,320 mg kg−1, with the highest concentrations found in the Ilha de Maré population, where soils showed a clear Cu enrichment. Total Cu content did not explain the abnormally high Cu concentrations observed in crabs from Pitinga, where total content in soil was low. Geochemical partitioning indicated that most of the potentially bioavailable Cu was found in the oxidizable fractions, pyrite and organic matter. Pyrite oxidation during the dry season led to increased Cu bioavailability. This process was of relevance in soils of the Pitinga mangrove, where sulfide oxidation led to soil acidification and to an increase in Cu associated with the most labile fractions.

The aim of the present study was to analyze the response to exposure to pollutants (trace elements and organic pollutants) using biomarkers (micronucleated cells and glutathione S-transferase and catalase activity) in uçá crab Ucides cordatus. The study was carried out at four sites: Cacha Prego (CP) and Ponta Grossa (PG), areas with low anthropic activity; and Ilha de Maré (IM) and Pitinga (PT), areas affected by industrial activity. At each site, soil and crab samples were collected to analyze the contents of potentially toxic elements (total concentration and chemical partitioning of trace elements), polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs). Both total concentrations and geochemical fractions of Cu, Zn, and Ni in soils were significantly higher in IM. Likewise, higher reactive Pb contents were observed in mangroves both in IM and in PG. Values above quality limits were observed for organic pollutants (PAHs) in soils from CP and PT, while PCB contents were below the maximum permissible levels. Metals in crabs also showed spatial variations, with higher Cu concentrations in all tissues in IM and PT and higher Ni concentrations in hepatopancreas in PT during the dry season. PAH values in crabs did not show spatial variations; however, crustaceans with contents above maximum limits in their muscle tissue were found in CP. Crabs from the Baia de Todos Santos showed different responses in biomarker expression, with higher enzymatic activity and greater numbers of micronucleated cells in crabs from IM, suggesting oxidative stress and genotoxicity in this mangrove forest.
