Feeding and social behavior of the piabanha, Brycon devillei (Castelnau, 1855) (Characidae: Bryconinae) in the wild, with a note on following behavior

Abstract: Knowledge concerning the behavior of wild freshwater fishes in Brazil is restricted to a few studies, despite such studies being able to answer fundamental questions about conservation. Species of Brycon are amongst the most threatened in the Neotropics, particularly in southeast Brazil, due to anthropogenic activities in this region. This study investigated the feeding and social behaviors of the endangered fish, Brycon devillei in the Preto River, Jequitinhonha basin, Minas Gerais State, Brazil. Behavioral d… Show more

“…Its body weight may reach more than 7 kg, thus it is a very important fish for commercial and sport fishing (Gonçalves et al, 2006). In riparian forests in the Neotropics, fruits and seeds is an essential part of the diet of adult Brycon species; and thus these fish play an important role in the dispersal of plants (Azevedo et al, 2011). This migratory species is threatened in rio São Francisco, and it is included in the Red List of the International Union for Conservation of Nature (IUCN), in the category of vulnerable due to an inferred population reduction of greater than 30% over the last ten years due to overfishing and destruction of riparian vegetation (Reis & Lima, 2009).…”

“…Esta dieta, basada principalmente en macroinvertebrados acuáticos, fue descrita con anterioridad para la misma especie en la cuenca del Pacífico colombiano (Botero-Botero y Ramírez-Castro, 2011) y otras cuencas como la del río Magdalena (Restrepo-Santamaría et al, 2022) y para otras especies del mismo género (Azevedo et al, 2011). Dicha estrategia adaptativa de consumir alimentos de manera generalista le permite a la especie distribuirse en hábitats acuáticos diversos (Restrepo-Santamaría et al, 2022).…”

“…Desbalance en la cadena trófica que puede poner en riesgo la supervivencia de varias especies y comprometer la estabilidad del ecosistema Impartir talleres en la zona advirtiendo los riesgos que implica introducir especies en el lago Pesca no controlada y utilización de artes de pesca destructivos Disminución de las poblaciones de las especies afectadas Colocar rótulos donde explícitamente se indique la ilegalidad de la actividad y las medidas legales (multas u otras); crear un grupo comunal que vigile la zona varias veces a la semana Young, 2011;Kasumyan & Marusov, 2015). A. aeneus además es muy importante en la red trófica, dado su papel en el ecosistema como uno de los principales recicladores de nutrientes (nitrógeno y fósforo), en hábitats donde hay poco aporte de los mismos (Small et al, 2011).…”
