Vermiculated sailfin catfish, Pterygoplichthys disjunctivus (Actinopterygii Siluriformes: Loricariidae): Invasion, biology, and initial impacts in east Kolkata Wetlands, India

Background. The East Kolkata Wetlands in India (a Ramsar site) are sewage-fed, nutrient-rich water bodies successfully used for fish production. The vermiculated sailfin catfish, Pterygoplichthys disjunctivus (Weber, 1991), exotic to India, has invaded these wetlands. The management and control of this catfish has been hindered, because of...
