Resumo: | The aim of this study was to analyze the diet of Ageneiosus ucayalensis from Reservoir Hydroelectric Plant Coaracy Nunes, in Ferreira Gomes / AP. Samples were collected bimonthly in three sampling stations in the reservoir between July / 2009 and July / 2010. Samplings were conducted using gillnets, organized in batteries each with seven networks and different distances between us. After capture, were performed specimens biometrics and their stomachs removed, fixed and stored for laboratory analysis. The sex ratio was performed in order to determine whether there was significant difference between the sexes. Food items of stomach contents were grouped into broad categories and analyzed by the methods of frequency of occurrence and volume, combined in Alimentary Index (IAI). The results showed that the sex ratio was 1: 1, with a slight predominance of females. As for food, the species proved to be carnivorous, with a diet based primarily on microcrustaceans, crustaceans, fish and unidentifiable material. Seasonal variations in diet were not clear and probably are related both to the availability of prey in the area as the manipulation of the water level of the reservoir by the control gates.Keywords: Feed; HPP; fish; Siluriformes; IAi. |

As amostragens foram feitas bimestralmente em três estações de coleta na área do reservatório entre julho/2009 e julho/2010. As coletas foram realizadas utilizando redes de espera, organizadas em baterias com sete redes cada e diferentes distâncias entre nós. Após a captura, foi realizada a biometria dos exemplares, sendo seus estômagos retirados, fixados e conservados para análise em laboratório. A proporção sexual foi realizada no intuito de verificar se houve diferença significativa entre os sexos. Os itens alimentares do conteúdo estomacal foram agrupados em categorias amplas e analisados através dos métodos de frequência de ocorrência e volumétrico, combinados no Índice de Importância Alimentar (IAi), por período sazonal. Os resultados evidenciaram que a proporção entre os sexos foi de 1:1, com uma leve predominância de fêmeas. Quanto à alimentação, a espécie mostrou-se carnívora, com a dieta baseada principalmente em microcrustáceos, crustáceos, peixes e material não identificável. Variações sazonais na dieta não foram nítidas e, provavelmente, estão relacionadas tanto à disponibilidade das presas na área quanto à manipulação do nível da água do reservatório pelo controle de comportas.Palavras-chave: alimentação, UHE, peixes, Siluriformes, IAi.Universidade Federal do AmapáELETRONORTE/APSá-Oliveira, Júlio CésarPeixoto Maciel, Anaytatyana GóesAraujo, Andrea Soares deIsaac-Nahum, Victoria Judith2014-10-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Avaliado pelos Paresapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/96310.18561/2179-5746/biotaamazonia.v4n3p73-82Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 4, n. 3 (2014); 73-822179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPporhttps://periodicos.unifap.br/index.php/biota/article/view/963/v4n3p73-82.pdfAmazonia; Amapá; BrasilDireitos autorais 2014 Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2016-04-12T19:58:16Zoai:ojs.pkp.sfu.ca:article/963Revistahttp://periodicos.unifap.br/index.php/biotaONGhttps://periodicos.unifap.br/index.php/biota/oai||juliosa@unifap.br2179-57462179-5746opendoar:2016-04-12T19:58:16Biota Amazônia - Universidade Federal do Amapá (UNIFAP)false |
