Resumo: | The study of species feeding helps in understanding aspects of their biology and population dynamics. The purpose of the present research was to analyze the food content, characterizing the feeding of the flying fish Hirundichthys affinis collected in two sites in the Atlantic Ocean Southwest Tropical. The surveys were carried out in July 2016 in the vicinity of the PIRATA Program buoy located in the western equatorial Atlantic, distant 323 nautical miles from the Areia Branca - RN, and in the slope off Macau – RN in January of 2017. Stomachs and guts contents were analyzed by the identified categories, regarding frequency and volumetric frequencies, which were combined in the calculation of Alimentary Index (IAi). The prey item volumes were ordered in NMDS and their significant differences tested by PERMANOVA, while the contribution of each food item to the differences between the sites was evaluated through the SIMPER analysis. However, morphometric, spatial and temporal factors influenced in a relevant way the diet of the species at each point, classifying H. affinis collected in the vicinity of the PIRATA float as carcinophagous and individuals caught off the coast of Macau as piscivorous tending to carcinophagous |

A proposta do presente trabalho foi analisar o conteúdo alimentar, caracterizando a alimentação do peixe voador Hirundichthys affinis coletado em dois pontos no Oceano Atlântico Sudoeste Tropical. As coletas foram realizadas no mês de julho de 2016 nas proximidades da boia do Programa PIRATA localizada no Atlântico Oeste Equatorial, distante 323 milhas náuticas do cais de origem, Areia Branca - RN e na costa do município de Macau - RN no mês de janeiro de 2017. Estômagos e intestinos foram analisados, das categorias identificadas, foram obtidas as frequências de ocorrência e volumétrica, combinadas no cálculo de Índice Alimentar (IAi). Os volumes dos itens foram ordenados em NMDS e as suas diferenças testadas em PERMANOVA, a contribuição de cada item alimentar para as diferenças entre os pontos foi avaliada através da análise SIMPER. As análises dos conteúdos alimentares permitiram o enquadramento da espécie na categoria trófica de carnívora com tendência a carcinofagia, contudo, fatores morfométrico, espacial e temporal influenciaram de forma relevante na dieta da espécie em cada ponto, classificando H. affinis coletado nas proximidades da boia PIRATA como carcinófago e os indivíduos capturados na costa de Macau como piscívora com tendência a carcinofagiaCoordenação de Aperfeiçoamento de Pessoal de Nível Superior2018-03-28application/pdfporCC-BY-SAinfo:eu-repo/semantics/openAccessÍndice Alimentar (IAi)Macau – RNBoia PIRATACarcinófagoAlimentary Index (IAi)Macau - RNBoia PIRATACarcinophagousCNPQ::CIENCIAS BIOLOGICAS::ECOLOGIAAlimentação do peixe-voador Hirundichthys affinis (Gunther, 1866) no Atlântico Sudoeste Tropicalinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisPrograma de Pós-Graduação em Ecologia e ConservaçãoUFERSABrasilreponame:Biblioteca Digital de Teses e Dissertações da UFERSAinstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSATEXTAbílioBDN_DISSERT.pdf.txtAbílioBDN_DISSERT.pdf.txtExtracted texttext/plain59301https://repositorio.ufersa.edu.br//bitstream/prefix/839/3/Ab%c3%adlioBDN_DISSERT.pdf.txt06b57154cc6a9df162235bd43dbb4909MD53THUMBNAILAbílioBDN_DISSERT.pdf.jpgAbílioBDN_DISSERT.pdf.jpgGenerated Thumbnailimage/jpeg1251https://repositorio.ufersa.edu.br//bitstream/prefix/839/4/Ab%c3%adlioBDN_DISSERT.pdf.jpg1a742513e7e41365dd816c4182e2e8b1MD54ORIGINALAbílioBDN_DISSERT.pdfAbílioBDN_DISSERT.pdfapplication/pdf904218https://repositorio.ufersa.edu.br//bitstream/prefix/839/1/Ab%c3%adlioBDN_DISSERT.pdf56c0d02537c6cfc6883dc9f17965555cMD51LICENSElicense.txtlicense.txttext/plain;
