Última Influence of cage farming on feeding and reproductive aspects of Pimelodus maculatus Lacépède, 1803 (Siluriformes: Pimelodidae) in the Chavantes reservoir, Brazil - doi: 10.4025/actascibiolsci.v36i1. 3 Brandão, Heleno; Universidade Estadual Paulista “Júlio de Mesquista Filho”; Santana, Julio Cesar de Oliveira; Universidade Estadual de Campinas; Ramos, Igor Paiva; Universidade Estadual Paulista “Júlio de Mesquista Filho”; Carvalho, Edmir Daniel; Universidade Estadual Paulista “Júlio de Mesquista Filho”. This study evaluated the diet and reproductive aspects of the population of Pimelodus maculatus around net cage fish farming in order to assess the possible impacts of this activity. Monthly collections were performed from March 2008 to February 2009 on two populations: one close to the net cages (NC) and one from an area not influenced by these cages denominated the “reference site” (RS). Results of the Alimentary Index (AI), Gonadosomatic Index (GSI), reproductive potential and histological analysis were obtained for both NC and RS populations. The population from NC used leftover food (ration) that escapes from net cages as the main food item (99.3%). For the RS population, the detritus item was the more important food source (51.7%). The Detrended... Tipo: Info:eu-repo/semantics/article Palavras-chave: 2.05.02.00-1 fish; Biology; Neotropical reservoir; Paranapanema river Ecologia. Ano: 2013 URL: http://periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/21039 Diet and niche breadth and overlap in fish communities within the area affected by an Amazonian reservoir (Amapá, Brazil) 42 SÁ-OLIVEIRA,JÚLIO C.; ANGELINI,RONALDO; ISAAC-NAHUM,VICTORIA J.. We investigated the niche breadth and overlap of the fish species occurring in four environments affected by the Coaracy Nunes reservoir, in the Amapá Brazilian State. Seasonal samples of fishes were taken using a standard configuration of gillnets, as well as dragnets, lines, and cast­nets. Five hundred and forty stomach contents, representing 47 fish species were analyzed and quantified. Niche breadth and overlap were estimated using indexes of Levins and Pianka, respectively, while interspecific competition was evaluated using a null model (RA3). ANOVA and the Kruskal­Wallis test were used, respectively, to evaluate differences in niche breadth and overlap between areas. The data indicate that the majority of the fish species belong to the piscivore,... Tipo: Info:eu-repo/semantics/article Palavras-chave: Competition; Neotropical reservoir; Diet; Species coexistence.
