Abstract (en):
The presence of striped catfish (Pangasianodon hypophthalmus) in inland waters of Colombia is recorded. This Asian species was recently brought into the country illegally. Although Colombia´s environmental legislation does not allow the introduction of alien species, in August 2015 artisanal fishermen captured a specimen of striped catfish at the Rio Carare, a tributary of the middle basin of the Rio Magdalena. To date eight confirmed records of this species exist in the same region. The striped catfish must be considered as an exotic species in Colombia, and the consequences of this introduction are uncertain, both for aquatic ecosystems and for the regional fish fauna, with many important fishery species in the basin.
Abstract (es):
Se registra la presencia del pez basa (Pangasianodon hypophthalmus) en aguas continentales de Colombia. Esta especie asiática fue introducida recientemente de manera ilegal al país. Aunque la legislación ambiental de Colombia no permite la introducción de especies foráneas sin autorización previa, en agosto de 2015 pescadores artesanales capturaron un ejemplar de esta especie en el río Carare, afluente de la cuenca media del río Magdalena, y a la fecha se cuenta con registros confirmados de esta especie en ocho localidades de la misma cuenca. El pez basa debe considerarse como una especie exótica en Colombia, y las consecuencias de su introducción son inciertas tanto para los ecosistemas acuáticos, como para la misma ictiofauna regional.
