“…Tambaqui is one of the most unusual migratory fishes in the Amazon because of its possession of numerous gill rakers, which are associated with a zooplanktivorous diet in whitewater river floodplain lakes and molar‐like teeth used for feeding on fruits and seeds in flooded forests after just a few months of age (Araujo‐Lima & Goulding, ). The detritivorous jaraquis are closely related, have similar life histories and produce hybrids in the wild (Ribeiro, ). Blackwater and clearwater river flooded forests explained 95% of the catch variance for these species ( r 2 adj = 0.951; N = 9; F = 155.769; p < 0.001) and 72% for matrinchã ( r 2 adj = 0.717; N = 9; F = 11.138; p = 0.010).…”

Infrastructure development and overfishing in the Amazon make it imperative to define adequate scales for the ecosystem‐based management of commercial fisheries and the wetlands on which they depend. We mapped fisheries and fish ecology data from Brazil, Peru, Bolivia and Colombia to an explicit GIS framework of river basins and mainstems. Migratory species account for more than 80% of the known maximum catches of commercial fisheries across the Amazon. Of these migratory species, we nominated six long‐distance migratory fish taxa as flagship species to define the two main commercial fishery regions. The migrations of at least one goliath catfish species define a large‐scale longitudinal link joining the Andes, Amazon Lowlands and Amazon River estuary. Migratory Characiforms demonstrate interbasin wetland connectivity between nutrient‐rich and nutrient‐poor rivers over at least 2 million km2, or about one‐third of the Amazon Basin. We show that flooded forest area is the most important wetland variable explaining regional variations in migratory characiforme biomass as indicated by maximum annual fishery catches. The sustainable management of Amazon fisheries will require transnational cooperation and a paradigm shift from local community management alone to a more integrated approach that considers both rural and urban consumers and challenges, and the realistic life histories of migratory species.

“…(2006), however, presented evidence of hybridization between Cichla kelberi and Cichla piquiti in the Rio Paraná, in which both species are introduced. The only other wild hybrid involving two South American fish species is that between Semaprochilodus insignis and Semaprochilodus taeniurus (Prochilodontidae) reported from the Amazon basin by Ribeiro (1985) based on morphological characters only.…”

“…Desse modo, na Amazônia onde há uma alta diversidade, a frequência de hibridação tende a ser menor (HUBBS, 1955). Entretanto, existem muitos relatos de híbri-dos de peixes nestas regiões (RIBEIRO, 1985;TEIXEIRA;OLIVEIRA, 2005).…”

GASQUES, L. S.; FABRIN, T. M. C.; PRIOLI, S. M. A. P.; PRIOLI, A. J. A introdução do gênero Cichla [Block e Schneider, 1801] na planície de inundação do Alto Rio Paraná. Arq. Ciênc. Vet. Zool. UNIPAR, Umuarama, v. 17, n. 4, p. 261-266, out./dez. 2014. RESUMO:As espécies que compõem o gênero Cichla Block e Schneider, 1801 são piscívoras, possuem grande plasticidade fenotípica e oferecem cuidados para sua prole, motivos estes que as tornam invasoras de alto impacto ambiental. O conhecimento taxonômico e da diversidade genética são importantes para o monitoramento populacional das espécies introduzidas. O objetivo deste trabalho foi caracterizar as espécies e esboçar um histórico da presença do gênero Cichla na planície de inundação do alto rio Paraná evidenciando a problemática de sua introdução nesta região. Análises de diversidade genética em populações introduzidas na bacia do rio Paraná de Cichla kelberi [Kullander e Ferreira, 2006] e C. piquiti [Kullander e Ferreira, 2006] têm demonstrado a origem dos espécimes introduzidos assim como a sua hibridação. PALAVRAS-CHAVE: Tucunaré. Hibridação. Molecular. Espécie exotica. THE Cichla [BLOCK e SCHNEIDER, 1801] GENUS IN FLOODPLAINS OF THE UPPER PARANÁ RIVER ABSTRACT:The species constituting the Cichla [Block e Schneider, 1801] genus are piscivorous, present great phenotypic plasticity and provide care for their offspring, reasons that characterise these intruders as of high environmental impact. The taxonomic and genetic diversity knowledge is important for population monitoring of the introduced species. The aim of this study is to characterize the species and draw a history of the presence of the Cichla genus in the floodplain of the Las especies que componen el género Cichla Block y Schneider, 1801 son piscívoras, tienen gran plasticidad fenotípica y ofrecen cuidados a su prole, motivos estos que las vuelven invasoras de alto impacto ambiental. El conocimiento taxonómico y la diversidad genética son importantes para el monitoreo poblacional de las especies introducidas. El objetivo de este trabajo ha sido caracterizar las especies y esbozar un histórico de la presencia del género Cichla en la llanura de inundación del alto Río Paraná evidenciando la problemática de su introducción en esta región. Análisis de la diversidad genética en poblaciones introducidas en la bacía del Río Paraná de Cichla kelberi [Kullander y Ferreira, 2006] y C. piquiti [Kullander y Ferreira, 2006], ha demostrado el origen de los especímenes introducidos, así como su hibridación.
