Abstract
Abstract Data on the deep sea fishes found off the northern Brazilian coast are restricted to the results of the surveys of the RV Oregon, a research vessel of the North American National Marine Fisheries Service, and the REVIZEE Program. The REVIZEE Score-Norte Program focused on commercial fish species and natural resources with potential for exploitation on the continental shelf and slope off the northern coast of Brazil. In this sense, the REVIZEE Score-Norte Program generated little information on species of no commercial value, did not catalog its inventory in zoological collections, and did not publish species lists. Given this considerable knowledge gap on the deep-sea fish found off the North coast of Brazil, we compiled all the available data on the deep-sea fish of this region and also retrieved photographic records from the REVIZEE Score-Norte Program, including the PRODEMERSAL and PROTUNA projects. Considering the published records, specimens deposited in zoological collections, and the interpretation of photographic records, we compiled a list of 63 species of deep-sea fish from the North coast of Brazil. An additional 30 species were found in the published records from the PRODEMERSAL and PROTUNA, but were considered to be doubtful or pending confirmation.
Highlights
The northern Brazilian coast comprises the region between the mouths of the rio Oiapoque, which forms the frontier between Brazil and French Guiana, and the rio Parnaíba, which marks the frontier between the Brazilian states of Maranhão and Piauí
The lists compiled by the PROTUNA and PRODEMERSAL projects include a total of 36 species of deep-sea fish
Based on the photographic records made during the REVIZEE Score-Norte Program (22 species) and associated projects, PROTUNA (3 species) and PRODEMERSAL (17 species), we identified a total of 37 species (Tab. 1, A column), in a recent collection effort in the Great Amazon Reef System by CEPNOR (Alexandre Marceniuk et al, 2020 pers. comm.)
Summary
The northern Brazilian coast comprises the region between the mouths of the rio Oiapoque, which forms the frontier between Brazil and French Guiana, and the rio Parnaíba, which marks the frontier between the Brazilian states of Maranhão and Piauí. Some inventories on the coastal fish fauna have been conducted (Eskinazi, Lima, 1968; Rocha, Rosa, 2001; Espírito-Santo, Isaac, 2005; Moura et al, 2016; Marceniuk et al, 2017, 2019), information on the deep-sea fishes is restricted basically to the results of two long-term surveys One of these surveys was undertaken by the Oregon, a research vessel of the North American National Marine Fisheries Service, while the other was part of the Brazilian National Program for the Assessment of the Sustainable Potential of Natural Resources in the Exclusive Economic Zone (REVIZEE). The surveys carried out by the National Marine Fisheries Service generated an enormous amount of scientific material, which is deposited in North ni.bio.br | scielo.br/ni
