Skeletal deformities in the Atlantic Goliath Grouper, Epinephelus itajara (Perciformes: Epinephelidae) JOSÉ A.C.C. NUNES, LEONARDO S. BUENO, ÁTHILA A. BERTONCINI, JOHNATAS ADELIR-ALVES, MATHEUS O. FREITAS, et al. Anais Da Academia Brasileira De Ciencias, 2025 Several studies pointed out that skeletal abnormalities, although widespread among species, are rare in wild populations. There is a gap in the knowledge of such anomalies on endangered fish species regarding types of deformities, geographical distribution, and possible consequences on key behaviors. Here, we describe new records of skeleton deformities in the endangered Atlantic Goliath Grouper (AGG), Epinephelus itajara, based on 20 years of scientific dives and collections focused on studing AGG spawning aggregations and movement using telemetry in Florida (U.S.) and along the Brazilian coast. Five different deformities were recorded (pughead, shorttail, pughead no-eye, finless, and shorttail-pughead). We also compiled and discussed previous records from the literature and the challenges posed by these deformities. We proposed hypotheses related to the challenges imposed by each type of deformity on wild juvenile AGG. Despite the low frequencies in wild populations, abnormal individuals may have a higher survival rate in aquaculture facilities.
Scientific diving in Brazil: history, present and perspectives Tatiana S. Leite, Igor E. Pinheiro, Flávio Berchez, Áthila A. Bertoncini, Oswaldo M. Del Cima, et al. Ocean and Coastal Research, 2023 internal waters; 5) an analysis of the evolution of scientific diver training in Brazil, including a diagnosis on training; 6) the history and updates of the rules, regulations, and safety of SD. Given all the potential of diving combined with specific techniques for research, monitoring, and marine and limnic science in Brazil, we aim to understand the evolution of scientific diving teaching and to outline perspectives in the country, as it is crucial for the training of qualified scientists capable of performing these underwater tasks. Finally, we present future plans for the development of this activity in Brazil from the point of view of research and the labor market. Abstract
New occurrences of the nonindigenous orange cup corals tubastraea coccinea and T. tagusensis (Scleractinia: Dendrophylliidae) in southwestern Atlantic Cláudio L. S. Sampaio, Ricardo J. Miranda, Rodrigo Maia-Nogueira, José De Anchieta C.C. Nunes Check List, 2012 The genus Tubastraea, with natural occurrence in the Pacific Ocean, was reported for the first time in Brazil along the coast of Rio de Janeiro. Since then it has also been reported in other sites along the south and southeast Brazilian coasts in oil platforms and rocky shores. We describe for the first time the occurrence of Tubastraea tagusensis and T. coccinea in the Northeastern coast of Brazil. The corals were found in the state of Bahia, sitting on shipwrecks, marina jetties as well as occupying space on a coral reef.
First record of the Pacific short-tailed Shearwater Puffinus tenuirostris (Temminck, 1835) for the Atlantic Ocean Revista Brasileira De Ornitologia, 2008
Association between juvenile reef fish and the Caribbean reef squid Sepioteuthis sepioidea on north-eastern Brazilian coastal reefs José de Anchieta C.C. Nunes, Laís de C.T. Chaves, Rodrigo Maia-Nogueira, Cláudio L.S. Sampaio Journal of the Marine Biological Association of the United Kingdom, 2007 This article reports on four different juvenile reef fish species, Polydactylus virginicus, Haemulon aurolineatum, H. steindachneri and Carangoides bartholomaei swimming along with schools of the caribbean reef squid Sepioteuthis sepioidea. Three different behaviours were observed. This is the first record of this squid species on Brazilian reef habitats. We suggest that this behaviour is mainly related to protection for juvenile fish against potential pelagic predators.
Haematological analysis and clinical chemistry of ALT, AST and creatinine of a southern elephant seal, Mirounga leonina (linnaeus, 1758), found on the Salvador coast, Bahia Bruno Lopes Bastos, Bruno Lopes Gerson de Oliveira Norberto, Rodrigo Maia-Nogueira, José Eugênio Guimarães Brazilian Journal of Veterinary Research and Animal Science, 2006 O Centro de Resgate de Mamíferos Aquáticos (CRMA) tem trabalhado desde 1999 com o resgate e a reabilitação de cetáceos e pinípedes em situação de encalhe no litoral do Estado da Bahia. O presente trabalho objetiva apresentar e avaliar os resultados de hemogramas e dosagens séricas de alanina aminotranferase (ALT), aspartato aminotransferase (AST) e creatinina realizados em um exemplar de elefante-marinho-do-sul, Mirounga leonina (LINNAEUS, 1758), encontrado no dia 11 de fevereiro de 2002 na praia da Barra, litoral de Salvador, BA. Tratava-se de um filhote macho, com 137cm de comprimento e peso aproximado de 49kg, com estado nutricional debilitado, um ferimento no lado direito na altura da escápula. O exemplar permaneceu em acompanhamento clínico por 56 dias, sendo vermifugado com Febendazole, o ferimento suturado e tratado com álcool iodado, Nitrofurazona solução e Tartarato de Ketanserina, simultaneamente com Enrofloxacina 10%, Potenay®, Complexo B e Benerva®. No dia 16 seguinte apresentou um quadro de conjuntivite unilateral direita, sendo tratado até o final de sua estadia com pomada oftálmica à base de Cloridrato de Cloranfenicol. Durante este período colheu-se um total de seis amostras de sangue, sendo três para a realização de hemograma e as demais para dosagem de ALT, AST e creatinina. De acordo com os resultados dos eritrogramas o filhote desenvolveu um quadro de anemia, classificada como microcítica e normocrômica. Com relação aos leucogramas, destacou-se linfopenia, eosinopenia e monocitopenia, possivelmente influenciado pelas condições de estresse e o manejo. Constatou-se nos exames bioquímicos valores diminuídos para a AST e creatinina, porém não representando a existência de um quadro patológico de significância clínica.
