“…This is also the case for Parodon caliensis, which has suffered similar decimation of its populations and has disappeared from sites where we once easily collected it (Londoño-Burbano & Román-Valencia, 2010).…”

“…Tooth characteristics have traditionally been used to define the three parodontid genera: small lateral teeth are present on the sides of the lower jaw of Parodon Valenciennes, but absent in Apareiodon Eigenmann and Saccodon Kner (Eigenmann, 1916;Londoño-Burbano & Román-Valencia, 2010). The diagnosis of taxa within this family is complicated by several factors: they have relatively small, weak teeth that are easily broken, and thus have frequently been overlooked or misinterpreted; and many species were described without a diagnostic comparison with other species, in very brief, incomplete reports that were sometimes based on erroneous observations (Pavanelli, 2003) leading to nomenclatural uncertainty and instability.…”

“…The number of cusps on these teeth is diagnostic for Parodon species, but not for Saccodon, which show dental polymorphism (Roberts, 1974a). In recent studies, pigmentation patterns of the body and the type of teeth are the principal morphological differences found to be useful to differentiate species (Jesus et al, 1999;Londoño-Burbano & Román-Valencia, 2010). Parodontids occur in Panama and in most South American drainages with the exception of those in southern Bahia State on the Atlantic coast of Brazil, Patagonia, and the main channel of the Amazon River (Pavanelli, 2003).…”

We review species of Parodon Valenciennes, 1850 from the Magdalena, Cauca, Orinoco, Amazonas, Atrato and CaribbeanGuajira River basins of Colombia using meristic and morphological characters. We recognize eight valid species, five previously described: P. apolinari Myers, from the Orinoco River basin; P. buckleyi Boulenger and P. pongoensis (Allen) from the upper Amazon; P. caliensis Boulenger, from the upper Cauca River drainage; and P. suborbitalis Valenciennes, from Lake Maracaibo basin. Three new species are described: P. alfonsoi, from the lower Magdalena River drainage; P. magdalenensis, from the middle Magdalena and upper Cauca River drainages; and P. atratoensis, from the Atrato River basin. We redescribe Parodon suborbitalis using type specimens and topotypes, and designate lectotypes. A taxonomic key is included for identification of the species, as well as geographic distribution maps.Espécies de Parodon Valenciennes, 1850 provenientes das bacias dos rios Magdalena, Cauca, Orinoco, Amazonas, Atrato e Caribe-Guajira da Colômbia são revisadas com base em caracteres merísticos e morfológicos. Oito espécies são consideradas válidas, sendo cinco previamente descritas: P. apolinari Myers, da bacia do rio Orinoco, P. buckleyi Boulenger e P. pongoensis (Allen) do alto rio Amazonas, P. caliensis Boulenger do alto rio Cauca e P. suborbitalis Valenciennes da bacia do lago Maracaibo. Três novas espécies são descritas: P. alfonsoi, do baixo rio Magdalena; P. magdalenensis, do médio rio Magdalena e da bacia superior do rio Cauca e P. atratoensis, da bacia do rio Atrato. Parodon suborbitalis é redescrita a partir de espécimes-tipo e topótipos. Designam-se lectótipos de P. suborbitalis. Uma chave para identificação das espécies é incluída, bem como mapas de distribuição geográfica.

“…Una vez dispuestos en los recipientes, los peces se depositaron en un tanque de 250 L con aireadores para su posterior conteo y registro fotográfico. Cada ejemplar fue identificado a nivel de especie con claves taxonómicas especializadas (Dahl, 1971;Londoño-Burbano & Román-Valencia, 2010;Maldonado-Ocampo et al, 2005;Miles, 1971;Román-Valencia & Arcila-Mesa, 2010;Vari, 2001) y la validez de su nombre siguió a Fricke et al (2021). Después de la manipulación, los ejemplares fueron liberados en el canal principal del río Porce (caudal ambiental) (Figura 2).…”

Rescate de peces aguas abajo de la presa Porce III (Colombia) para reducir su mortalidad

En la cuenca del río Magdalena, las actividades de rescate de peces son una medida de manejo ambiental utilizada para reducir su mortalidad en el área próxima a los embalses. Cuando se realiza la apertura y posterior cierre de compuertas del vertedero, producto de la operación de la central hidroeléctrica Porce III, aguas abajo de la presa se crean hábitats acuáticos temporales en forma de pozas marginales de lecho rocoso, en donde se presentan atrapamientos de peces. El objetivo del rescate es reubicarlos al canal principal del río para reducir su mortalidad. Entre los años 2013 y 2020 se capturaron 4927 individuos, representantes de 28 especies, 12 familias y cinco órdenes. Reubicamos a 4704 individuos nuevamente en el río Porce, siendo las especies de los géneros Chaetostoma, Andinoacara, Astyanax y Rhamdia los de mayor captura. También se capturaron especies potamodromas de la familia Pochilodontidae, cuya presencia próxima a la presa se debe posiblemente a migraciones que realizan para llevar a cabo su reproducción. Estas acciones de rescate y reubicación, producto de la operación de las centrales hidroeléctricas, deben ser replicadas en la cuenca como estrategia para mitigar los impactos ambientales ocasionados por la fragmentación del hábitat.

“…La familia Parodontidae está compuesta por los géneros Parodon valenciennes 1849 y Saccodon Kner 1863 (Londoño-Burbano & Román-valencia, 2010), con amplia distribución geográfica en el centro y sur de América, desde el Canal de Panamá hasta la cuenca del Río de la Plata en Argentina, excepto en las cuencas del sur del Estado de Bahía en Brasil en la Costa Atlántica, la Patagonia, y el canal del río Amazonas (Pavanelli, 2003).…”

Reproduction of Saccodon dariensis (Teleostei: Parodontidae) in Guatapé River tributaries, Magdalena River basin, Colombia. The Andean mountain region of Colombia has a high diversity of fish, with high number of endemic species. To promote their protection and conservation, the knowledge of their general and reproductive biology is necessary. With this aim, the reproductive biology of Saccodon dariensis, in the Peñoles and El Cardal creeks, Guatape River mid-basin, Magdalena River Basin, was studied, to determine reproductive differences between individuals with different oral polymorphism (morpho i vs. morpho iv, according to Roberts, 1974), and to define a possible spatial or temporal reproductive isolation. Ten field samplings were carried out between
