Despite a strong increase in research on seamounts and oceanic islands ecology biogeography, many basic aspects of their biodiversity are still unknown. In the southwestern Atlantic, Vitória-Trindade Seamount Chain (VTC) extends ca. 1,200 km offshore Brazilian continental shelf, from Vitória seamount to Trindade Martin Vaz. For long time, most biological information available regarded its islands. Our study presents analyzes an extensive database VTC fish biodiversity, built data compiled...
Abstract Data from fishing surveys employing bottom long‐lines were analysed to characterize the diversity, assemblages and distribution patterns of demersal fish along Brazilian outer shelf upper slope, between latitudes 13°S 22°S. Non‐metric multi‐dimensional scaling (MDS) cluster analysis indicate three distinct species separated primarily by depth (the 200 m isobath) secondarily latitude (19°S), suggesting a continual transition latitudinal gradients in study area. Species richness was...
Microplastics (MPs:
Foram analisadas as concentrações de mercúrio total (THg) em tecido muscular do tubarão azul Prionace glauca e teleósteo Xiphias gladius, vulgarmente conhecido como espadarte, provenientes das regiões sul sudeste da costa brasileira, para verificar se estas encontram dentro dos padrões legais consumo humano. As amostras foram obtidas utilizando-se o programa REVIZEE, agosto a setembro 2001, por intermédio uma empresa pesca Itajaí, Santa Catarina. Foi analisado um 95 espécimes, testando-se...
The Stephanoberycoidei includes 23 genera and c. 94 species of deep‐sea teleosts commonly known as bigscales, pricklefishes, gibberfishes whalefishes. is one the least groups fishes, in spite their apparent relative abundance meso bathypelagic depths. Nine are reported here for first time Brazilian waters, most them represent new range extensions south‐western Atlantic Ocean. Those Melamphaes polylepis , typhlops Poromitra sp. Scopeloberyx robustus (Melamphaidae), Acanthochaenus luetkenii...
Collections made by two deep-sea expeditions off eastern Brazil between 11° and 23°S, revealed the occurrence of a rich fish fauna. A total 94 trawl stations were performed RV Thalassa Astro Garoupa, at depths from 200 to 2300 m. The fishes order Ophidiiformes are reported upon here, including 23 species three families: Carapidae (2), Ophidiidae (19) Bythitidae (2). Of these, 15 represent new records for Brazilian waters: Acanthonus armatus, Barathrites parri, Barathrodemus manatinus,...
The species composition, abundance and diversity patterns of the epibenthic megafauna fish community from tropical Brazilian continental margin were analysed based on 42 bottom trawls Campos Basin shelf slope. Trawls collected aboard R/V Gyre during autumn 2008 depths 13 to 2030 m. Overall, 452 belonging five main taxa identified: teleosts (Actinopterygii) represented by 196 species, crustaceans 113 echinoderms 108 species. These three groups contributed 92% taxa. Several (289) recorded only...
Abstract Fishes in the mesopelagic zone (200–1000 m) have recently been highlighted for potential exploitation. Here we assess global phylogeography Maurolicus , Pearlsides, an ecologically important group. We obtained new sequences from mitochondrial COI and nuclear ITS-2 multiple locations worldwide, representing 10 described species plus unknown central South Pacific taxon. Phylogenetic analyses identified five geographically distinct groupings, three of which comprise species. Species...
New collections made by the French research vessel Thalassa and Brazilian Astro Garoupa on continental slope, between 11° 23° S revealed a great diversity of deep-sea gadiforms obtained 200 2270 m. Of 34 species collected, 13 (38%) are being reported for first time in western South Atlantic one may represent new species. The most species-rich family area is Macrouridae (25 species), followed Moridae (4), Phycidae (2), Merlucciidae Bregmacerotidae (1). Most collected also found Gulf Mexico...
A review of the deep-sea anguilliform and saccopharyngiform eels collected by French R/Vs Marion Dufresne (1987), Thalassa (1999, 2000), Brazilian Astro Garoupa (2003) revealed a great diversity these groups on continental slope (11–23 o S, 19–40 W), in depth range 233 to 3450 m. Of 33 species collected, 13 (39.4%) are being reported for first time western South Atlantic. New taxa represented one recently described few other probably undescribed. The most species-rich family area was...
Twenty-nine species from 11 genera of Myctophidae were taken in daytime midwater and bottom trawl hauls off eastern Brazil (11o -22o S). Trawls performed aboard the French R/V Thalassa to depths 19 2271 m, including samples shelf, slope vicinity oceanic banks seamounts. Diaphus garmani was most abundant species, accounting for 84% all identified individuals with four other ( D. dumerilii , brachycephalus perspicillatus Myctophum obtusirostre ) accounted >95% myctophids caught. Regarding...
The age and growth of the snowy grouper, Epinephelus niveatus , from central south-eastern Brazil were studied by otolith analysis a sample 341 specimens, ranging 325 to 1216 mm in total length (TL) caught with bottom longlines between 1996 1998. Otolith grew proportionally increasing TL fish. Marginal increment indicated that single opaque band forms each year during autumn–winter. maximum estimated was 54 years, which significantly extends previously life-span 21–29 years for this species....
Recent pelagic and benthic trawling activities over the Brazilian continental slope between 11° 23°S captured nine species representing five genera of stomiiform family Sternoptychidae. Among these, three are new records for waters: Sternoptyx pseudodiaphana, Argyripnus atlanticus, Polyipnus sp. The known distributions Argyropelecus aculeatus Maurolicus stehmanni along coast extended northward to 13°S 16°S, respectively, while that diaphana is southward 13°S. hemigymnus, sladeni,...
A collection of fishes from the Brazilian continental slope between 11° and 23° S obtained through trawling revealed nine species Ipnopidae. Bathypterois bigelowi Bathytyphlops marionae represent first records south‐western Atlantic Ocean grallator is reported off Brazil for time. Four have their distribution extended in waters: phenax , quadrifilis viridensis Ipnops murrayi . An identification key Ipnopidae included.
Abstract Otolith shape analysis is a powerful method for fish stock identification. We compared the otolith of Pagrus pagrus (Linnaeus 1758) along with its distribution in four south‐western Atlantic regions where it commercially fished: Rio de Janeiro, Grande do Sul southern Brazil, Argentine‐Uruguayan Common Fishing Zone (UA) and Argentinian Exclusive (AR). shapes were by Elliptical Fourier Wavelet coefficients among specimens size range similar otoliths, morphometric parameters ages. Four...
Abstract Stomach contents analysis and stable isotope results indicate M. hubbsi is a generalist predator that feeds mainly on demersal fishes, followed by crustaceans cephalopods. Ontogenetic changes in diet were identified, with fish importance increasing the hake size. Smaller (<250 mm) fed mostly sepiolid Semirossia tenera (89.45%IRI) engraulid (89.96%IRI). Mid-sized (250–300 benthic such as Bellator brachychir (95.63%IRI) euphausiids (56.46%IRI), while larger (>300 heavily...
