Abstract

Notes on the discovery and ecology of the invasive armoured catfish Pterygoplichthys disjunctivus (Weber, 1991) and the exotic cichlid Amphilophus trimaculatus (Gunther, 1867) from Southern West Bengal, India.

Abstract

This paper documents the first occurrence of an intergrade form of the highly invasive, South American armoured suckermouth catfish Pterygoplichthys disjunctivus (Weber, 1991) from the brackish waters of the Sundarban Tiger Reserve, West Bengal, India and the exotic Central American cichlid Amphilophus trimaculatus (Gunther, 1867) from Southern Bengal, India. Another species of cichlid Etroplus suratensis (Bloch, 1790) native to Southern India is also recorded for the wild for the first time from West Bengal. Notes on the possible threats due to invasion, sources of introduction, extent of spread and management of these and other invasive species are discussed in the paper.
