First record of the Southeast Asian walking catfish, Clarias batrachus (Pisces: Clariidae), from the island of Mauritius, south-western Indian Ocean

Abstract

The presence of Southeast Asian walking catfish, Clarias batrachus, in Mauritian freshwater systems has been confirmed. Three female Clarias batrachus were caught in Rivière Sèche, close to the town of Phoenix, Mauritius (20°17′ S, 57°33′ E). This constitutes the first record of the introduction of this species into the wild on the island of Mauritius.
