Resumo: | Industrial shrimp fisheries in northern Brazil use vessels equipped with trawls of low selectivity that capture considerable amounts of non-target bycatch species, and consequently, generate fauna biomass. In this study, we aimed to examine the composition and distribution of ichthyofaunal bycatches associated with pink shrimp industrial fishery between May 2010 and June 2011. Seven vessels were monitored for a period of151 travel days, during which trawls were towed 461 times. The northern coast was subdivided into the Pará Continental Platform, Amazonas River Estuary (ARE), and Amapá Continental Platform (ACP). Perciformes was the most abundant order (68.91%); Sciaenidae, the most abundant family (55.89%); and Macrodon ancylodon, the most abundant species (23,48%). ARE and ACP are regions with high biological diversity and density of species and similar ichthyofauna. The similarities between ARE and ACP regions can be attributed to the Guiana Current, which carries most of the water drained from the rivers of the Amazon Basin along the coast of Amapá; it promotes the high productivity of these regions. Monitoring of shrimp trawl fishing in the northern coast of Brazil can contribute to the preservation of populations of endemic animal species such as Macrodon ancylodon and Stellifer rastrifer, which are frequently associated with shrimp bycatch and therefore, particularly affected by this type of fishing.Keywords: Farfantepenaeus subtilis; fish; Sciaenidae; industrial fishing. |

Este trabalho objetivou realizar o levantamento da composição e distribuição da ictiofauna acompanhante proveniente de pescarias industriais de camarão-rosa, no período de maio de 2010 a junho de 2011. Foram monitorados sete embarques, totalizando 151 dias de viagem, contabilizando 461 lances. Considerou-se as seguintes subdivisões: Plataforma Continental do Pará (CPA); Foz do Rio Amazonas (FAM); e Plataforma Continental do Amapá (CAP). A ordem mais abundante foi Perciformes (68,91 %). A família Sciaenidae se destacou com 55,89% de ocorrência e a espécie mais representativa foi Macrodon ancylodon (23,48%). A FAM e CAP são áreas com maior diversidade biológica, maior densidade por espécies e composição da íctiofauna semelhante. Essa similaridade, entre FAM e CAP, pode ser explicada pelo efeito da corrente das Guianas, que transporta grande parte da descarga dos rios da bacia Amazônica ao longo da costa do Amapá, resultando em uma região de elevada produtividade. O monitoramento de pesca de arrasto de camarões na costa norte do Brasil poderá contribuir na manutenção dos estoques de espécies típicas da fauna acompanhante deste recurso, como Macrodon ancylodon e Stellifer rastrifer que, devido a elevada frequência de ocorrência nas pescarias, sofrem maior impacto desse sistema de pesca.Palavras-chave: Farfantepenaeus subtilis, ictiofuna, Scianidae, pesca industrial.Universidade Federal do AmapáMinistério de Pesca e Aquicultura - MPAMaia, Breno PortilhoNunes, Zélia Maria PimentelHolanda, Francisco Carlos Alberto FontelesSilva, Victor Hugo SilvaSilva, Bianca Bentes2016-03-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Avaliado pelos Paresapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/165310.18561/2179-5746/biotaamazonia.v6n1p31-39Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 6, n. 1 (2016); 31-392179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPporhttps://periodicos.unifap.br/index.php/biota/article/view/1653/v6n1p31-39.pdfhttps://periodicos.unifap.br/index.php/biota/article/downloadSuppFile/1653/264Costa Norte do Brasil; Pará; AmapáMaio de 2010 a junho de 2011embarques pesca do camarão rosa; peixes.Direitos autorais 2016 Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2016-07-01T18:28:45Zoai:ojs.pkp.sfu.ca:article/1653Revistahttp://periodicos.unifap.br/index.php/biotaONGhttps://periodicos.unifap.br/index.php/biota/oai||juliosa@unifap.br2179-57462179-5746opendoar:2016-07-01T18:28:45Biota Amazônia - Universidade Federal do Amapá (UNIFAP)false |
