Abstract

Background. Ornamental freshwater fish releases constitute a remarkable proportion of the 100 worst invasive species worldwide. Early detection and knowledge of likely introduction vectors and pathways of potentially invasive fishes into sensitive habitats are key for their proper management, hence rapid and correct identification of their occurrence is crucial. Therefore, we tested the hypothesis that a newly-discovered catfish population was that of Clarias batrachus (Linnaeus, 1758), and that this introduction might be of single origin released by aquarium pet fish owners.
