Última Spatial and seasonal patterns in fish assemblage in Córrego Rico, upper Paraná River basin Neotropical Ichthyology Takahashi,Erico L. H; Rosa,Fabricio R. T.; Langeani,Francisco; Nakaghi,Laura S. O.. The upper Paraná River basin drains areas of intensive industry and agriculture, suffering negative impacts. The Córrego Rico flows through sugar cane fields and receives urban wastewater. The aim of this work is to describe and to compare the fish assemblage structure in Córrego Rico. Six standardized bimonthly samples were collected between August 2008 and June 2009 in seven different stretches of Córrego Rico. Fishes were collected with an experimental seine and sieves, euthanized, fixed in formalin and preserved in ethanol for counting and identification. Data were recorded for water parameters, instream habitat and riparian features within each stretch. Non-metric multidimensional scaling, species richness and diversity analysis were performed to...

Ano: 2013 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252013000100143 Biologia reprodutiva de três espécies simpátricas de peixes neotropicais: Pimelodus maculatus Lacépède (Siluriformes, Pimelodidae), Leporinus amblyrhynchus Garavello & Britski e Schizodon nasutus Kner (Characiformes, Anostomidae) do recém-formado Reservatório de Miranda, Alto Paraná Zoologia Vono,Volney; Silva,Luiz Gustavo M.; Maia,Bruno P.; Godinho,Hugo P.. The reproductive activity parameters of the teleosts Pimelodus maculatus Lacépède, 1803, Leporinus amblyrhynchus Garavello & Britski, 1987 and Schizodon nasutus Kner, 1859 was evaluated at a newly formed reservoir in the Araguari River, Paraná River basin, Southeast Brazil. The fishes were captured by gill nets bimonthly from November 1997 to November 1998 at three sampling stations. The stages of gonad development were identified macroscopically in the field and then confirmed by histological analysis in the laboratory. The females of all species reached larger standard length than the males. Pimelodus maculatus in reproductive activity were captured only in November, 1997 and January, 1998 whereas L. amblyrhynchus and S. nasutus were in activity...
