Despite a strong increase in research on seamounts and oceanic islands ecology and biogeography, many basic aspects of their biodiversity are still unknown. In the southwestern Atlantic, the Vitria-Trindade Seamount Chain (VTC) extends ca. 1,200 km offshore the Brazilian continental shelf, from the Vitria seamount to the oceanic islands of Trindade and Martin Vaz. For a long time, most of the biological information available regarded its islands. Our study presents and analyzes an extensive database on the VTC fish biodiversity, built on data compiled from literature and recent scientific expeditions that assessed both shallow to mesophotic environments. A total of 273 species were recorded, 211 of which occur on seamounts and 173 at the islands. New records for seamounts or islands include 191 reef fish species and 64 depth range extensions. The structure of fish assemblages was similar between islands and seamounts, not differing in species geographic distribution, trophic composition, or spawning strategies. Main differences were related to endemism, higher at the islands, and to the number of endangered species, higher at the seamounts. Since unregulated fishing activities are common in the region, and mining activities are expected to drastically increase in the near future (carbonates on seamount summits and metals on slopes), this unique biodiversity needs urgent attention and management.

Invasive coral species of the genus Tubastraea have been increasingly recorded in Southwestern Atlantic waters since the 1980s. Their invasion and infestation are mainly related to port and oil exploration activities. For the first time the presence of Tubastraea tagusensis colonies is reported in Esprito Santo State, colonizing a port shore area, and incrusting oil/gas platform structures situated in the southern Abrolhos Bank, which is part of the most important coral reef system of the South Atlantic Ocean. Tubastraea colonies exhibit fast growth and high recruitment rates, and colonized 40% of the analyzed structures in just four years. The projection of port and oil/gas industry growth for the Esprito Santo State (more than 300%) highlights an alert to the dispersal of this alien species to natural areas.

Global biodiversity declines and increasing rates of extinction necessitate the assessment and prediction of the vulnerability of species to extinction. Here, we examine the relationships between conservation status and ecological traits of reef fish species of the Brazilian biogeographical province. We used binomial tests and a logistic regression to address two questions. Do biological attributes differ between threatened and non-threatened fishes? Which combination of traits and impacts exerts greater influence on species threat status? Of the 559 species, 36 are categorized as threatened (compiled from global, national and local Red Lists). Three species are categorized as Critically Endangered, seven as Endangered and 26 as Vulnerable. Our analyses revealed that Elasmobranchii, sex-changing bony fishes and endemic species are the most vulnerable reef fishes in Brazilian waters. Body size and trophic category were identified as good predictors of the vulnerability of a species to extinction. Small-bodied species that are exploited by the ornamental trade and have complex reproductive strategies are also of concern. Such combinations of attributes could be of value in predicting which reef fish species elsewhere have a high risk of extinction. Copyright © Fauna & Flora International 2013.

Many reef fish use non-reef habitats (e.g. mangroves, estuaries, and seagrass/algae beds) during their life cycle. In this study we determined how many, and which percentage of Brazilian reef fish species that make use of non-reef habitats are considered threatened (i.e. red-listed) and/or targeted by fisheries. We compiled data for 559 reef fish species, which were sorted by habitat use, threat and/or target status. Three-quarters (N = 27) of all threatened species, and 87% (N = 207) of targeted species use non-reef habitats. São Paulo and the 'Hump of Brazil' (PB-AL) had the highest number of targeted species using non-reef habitats. Estuaries presented the highest number of both threatened and targeted species. Additionally, this is the habitat that has the lowest protection on the Brazilian coast. We suggest that conservation strategies should include the protection of ecological corridors among reefs and other habitats for an effective management of Brazilian reef fishes. © 2011 ABECO.

Fishes inhabiting rhodolith beds and reefs at mesophotic depths on the Abrolhos Shelf, which encompasses the largest and richest coral reef formation in the South Atlantic Ocean, were assessed through technical diving and remotely operated vehicles (ROVs). A total of 74 fish species were recorded, including at least one new species, one new record for the south-western Atlantic and six new records for the Abrolhos region. Overfishing, mining and port activities are already threatening many endangered and commercially important species recorded on the mesophotic reefs of Abrolhos Shelf, and the establishment of marine protected areas and off-reserve fisheries regulations are urgently needed.

Grammicolepis brachiusculus, commonly known as Thorny tinselfish, was previously cited from Brazilian waters, but not thoroughly documented. Here we report about a new record of this species, based on three voucher specimens, 169.2-196.3 mm SL, collected off Bahia, Brazil. This report extends the range of the species southwards for a distance of about 3,500 kilometers along the South American coastline. Given its rarity, an updated diagnosis of the species, and an identification key to the Western Atlantic species of Grammicolepididae, are provided. © 2012 Check List and Authors.

The rare ophichthid eel Asarcenchelys longimanus is reported for the first time from Bahia State, north-eastern Brazil. To date, only two specimens of A. longimanus, the holotype and a paratype, were known. The new finding extends its distribution to about 2400 km southwards along the Brazilian coastline and provides a new maximum size for the species. Comparisons of the morphometric and meristic data between our specimens and those used in the original description are provided.

This is the third in a series of reports describing new or rare records caught with circle hooks, a method only recently being employed in exploratory fishing in Brazilian deep waters. Here we report the presence of one family and two species of perciform fishes new to, or never formerly reported from, Brazilian waters: the longfin escolar, Scombrolabrax heterolepis (Scombrolacidae), and the extremely rare ocean bass Verilus sordidus (Acropomatidae). The specimens were collected in outer shelf and slope areas at depths between 300 and 500 meters. Given the rarity of the species reported herein, we also provide an updated diagnosis for each species. We also discuss the need of adequate reports when new records are added to such a large ocean area as the Southwestern Atlantic. Copyright © 2010 · Magnolia Press.

A new species of Anthiadinae, Odontanthias cauoh, is described from São Pedro and São Paulo Archipelago (SPSPA), Brazil, Equatorial Atlantic. The new species differs from its only Atlantic congener by a combination of several characters: pectoral-fin rays 20; total gill rakers on first arch 39; vomerine tooth patch with a posterior prolongation; pelvic fin not reaching base of last anal-fin ray; dorsal, anal and pelvic fins scaleless; and coloration (dorsal, anal, and pelvic fins mostly dark red). The record of the new species contributes to increase the fish endemism in SPSPA. Copyright © 2016 Magnolia Press.

The American sciaenid genus Macrodon presently consists of only two species, the Atlantic Macrodon ancylodon (Bloch & Schneider, 1801), and the Pacific Macrodon mordax (Gilbert & Starks, 1904). The two species are distinguished mainly by the number of pored scales on the lateral line (66-78 in M. ancylodon vs. 45-55 in M. mordax). The present study revalidates a third species, the second from the Atlantic, Macrodon atricauda (Günther, 1880), which is genetically, morphologically, and geographically distinct from M. ancylodon, occurring between the Brazilian state of Espírito Santo and northern Argentina. It has significant economic importance in the area and thus considerations about its conservation are also presented. Copyright © 2010 · Magnolia Press.
