Sailfin catfish indigenous to South America are very popular ornamental fish, having previously been introduced to many regions outside their native range. Two species, namely Pterygoplichthys disjunctivus and P. pardalis, are illegal but widespread in Indonesia. They have formed self-sustaining populations, exploited for feeding of domestic animals and locally for human consumption. Also possible hybrids of the two mentioned species were recorded. The surveyed populations were considered established which perfectly fits with the climate matching analysis. Further monitoring and inspection of regions highlighted to be suitable for sailfin catfish is recommended.
Résumé
Le pléco léopard voile, originaire d'Amérique du Sud, est un poisson d'ornement très populaire, ayant été introduit auparavant dans de nombreuses régions en dehors de son aire de répartition d'origine. Deux espèces, à savoir P. disjunctivus et P. pardalis, sont illégales mais très répandues en Indonésie. Elles ont formé des populations autonomes, exploitées pour l'alimentation des animaux domestiques et localement pour la consommation humaine. Des hybrides possibles des deux espèces mentionnées ont également été observés. Les populations étudiées ont été considérées comme établies, ce qui correspond parfaitement à l'analyse de la correspondance climatique. Il est recommandé de poursuivre la surveillance et l'inspection des régions jugées appropriées pour le pléco commun.
