“…Centropomus parallelus is now considered as amphidromous, i.e. it migrates between fresh water and salt water during a portion of its life cycle (Riede, 2004;Silvano et al, 2006;Fortes et al, 2014). It has a feeding regime mainly based on fishes, insects and crustaceans, although early juveniles are also zooplanktivorous (Corrêa & Uieda, 2007;Alvarez-Lajonchère & Tsuzuki, 2008;Feltrin-Contente et al, 2009).…”

Sixty Centropomus parallelus juveniles were collected in March 2013 in two locations (Tromomó and Guaraguaçu) inside the Paranaguá estuarine complex, southern Brazil. The habitat residency and movement patterns of the individuals were inferred from Sr:Ca ratios and age recorded in the otoliths. Data suggest that the species spawns preferentially in brackish areas mainly from October to January, and that growth rate during the early juvenile stage could be influenced by environmental salinity. Furthermore, the data also show that C. parallelus can occupy diverse salinity habitats and migrate among marine, brackish and freshwater areas within the Paranaguá estuarine complex, showing a high environmental plasticity and adaptation.

“…Fish and crustacean abundances were used to compare the two periods (before and after channel opening) considering faunal distribution in each season and the main environmental factors that contributed to this distribution. Habitat differences between sampling sites were not considered due to previous non‐significant results (Fortes et al , ). Abundance data were fourth root transformed to construct the association matrix aiming to reduce dominant species effects, and then the Hellinger distance calculated, following Legendre & Gallagher () in order to reduce data distortions (Rao, ), and to maintain the best compromise between linearity and resolution (Legendre & Legendre, ).…”

Before–after environmental impact assessment of an artificial channel opening on a south‐western Atlantic choked lagoon system

This study aimed to evaluate the human induced impact of a channel opening in a choked lagoon and attempted to establish the cause-effect links for the observed changes. The same lagoon system was sampled before and after the channel opening event, and the differences in fish and crustacean assemblages and environmental variables between these periods analysed. The opening of the artificial channel resulted in salinity increases, leading to a shift in species composition, favouring marine species and reducing abundance and diversity of previously dominant freshwater species. Furthermore, saltwater entrance into the choked lagoon caused an unexpected decrease in species richness and biomass, plus deterioration of ecosystem processes, reducing fishing capacity. The effects of salinity on the ecosystem vary depending on the ecosystem's composition and capacity to overcome salinity changes, thus specific monitoring projects are important strategies for developing coastal lagoon conservation management.

“…No presente estudo, foram identificados 30 táxons de decápodes planctônicos, sendo essa a maior riqueza já registrada para o grupo na baía de Guanabara. Não foram encontradas espécies exóticas e todos os táxons já haviam sido registrados em forma larval ou adulta, na baía ou em ecossistemas adjacentes (Oliveira, 1939;Vergara Filho et al, 1997;Lavrado et al, 2000;Fortes et al, 2014). O total de táxons foi superior ao observado no estuário do Rio Macaé-RJ (24 táxons) (Almeida et al, 2013), porém similar ao observado nos estuários dos Rios Piraquê-Açú e Piraquê-Mirim-ES (32 táxons) (Magris & Fernandes, 2011).…”

Com o objetivo de caracterizar a assembleia de crustáceos decápodes planctônicos da baía de Guanabara, foram feitas amostragens de zooplâncton em sete campanhas, de dezembro de 2012 a janeiro de 2014, principalmente nos meses de verão - período de desova do caranguejo-uçá, Ucides cordatus. Ao todo, foram analisadas 105 amostras, provenientes de cinco pontos do eixo norte-sul da baía. As amostragens foram feitas na margem leste, da APA de Guapimirim à saída da baía. Foram identificados 51 táxons zooplanctônicos, sendo 30 de crustáceos decápodes. No holoplâncton, Copepoda e Cladocera apresentaram as maiores densidades populacionais. Os decápodes foram encontrados em todas as amostras, sendo a maioria na fase larval, especialmente zoés. Dentre eles, observou-se predomínio de braquiúros (caranguejos e siris), especialmente larvas zoé I-II de Uca spp., Ucides cordatus, Eurytium limosum, Neohelice granulata e Pachygrapsus transversus e das Famílias Portunidae e Sesarminae. A diversidade média de decápodes foi baixa, sendo de 0,78 ± 0,34 bits.org-1. Foram encontradas larvas e pós-larvas do caranguejo-uçá, em todos os estádios de desenvolvimento, sendo o período de ocorrência coerente com o previsto. As maiores densidades larvais dessa espécie foram observadas em dezembro, na região intermediária da baía, com máximo de 106,9 org.m-3 (zoés l-ll). Apesar da degradação ambiental histórica, a riqueza de crustáceos decápodes observada na baía, apontou enorme potencial ecológico, especialmente como berçário e habitat. Contudo, comparando-se com ecossistemas mais conservados, densidades populacionais das larvas do caranguejo-uçá foram baixas, apontando a necessidade de maior conservação dos manguezais e das populações adultas.
