Caracterização da fauna acompanhante das pescarias da Costa Norte do Brasil: Uma análise dos últimos 10 anos da literatura científica

Abstract

The study of the fauna accompanying the fisheries is important to understand which are the damages caused to the biota and, consequently, to the ecosystem where the fishery is carried out. Many times this accompanying fauna has no economic importance, that is, it is not used and is discarded. In the last few years the subject has raised a more serious concern, both on the part of researchers and fishery managers. The objective of this work is to analyze the occurrence of the accompanying fauna of the main fisheries practiced in the North coast of Brazil in the last 10 years. In this study the following platforms were used to consult the bibliographies: Periódico CAPES, Google Acadêmico, Scielo and ScienceDirect. The bibliographies found were used to extract relevant information about the subject studied (which species were incidentally caught, the frequency, the place of collection/fishing, the year of collection, the type of fishing carried out). By analyzing the bibliographies, during the period analyzed, 274 species were found that make up the fauna accompanying fishing in the North Coast and are distributed in four types of fisheries (shrimp fishery, lobster fishery, piramutaba fishery, and various fish fisheries). In the shrimp fishery, there is a great incidence of species that belong to the Sciaenidae family and at the species level, the spiny dogfish (Macrodon ancylodon) is the one that is economically exploited. The mollusks that make up this accompanying fauna were counted in a total of 119, and among these species, only four species are used as accompanying fauna because of their appearance. This work showed a great variety of species that make up this accompanying fauna in the North Coast of Brazil and there are those species that present a higher frequency in the capture and that can be used to be commercialized (e.g. the hake (Macrodon ancylodon Bloch & Schneider, 1801), hake (Cynoscion jamaicensis Vaillant & Bocourt, 1883), snapper (Lutjanus purpureus (Poey, 1866)), but there is also the disposal of other part of these species.
