Invasive introduced fish species are well known for their deleterious impacts on aquatic biodiversity and environment. This study provides the first report on the occurrence of introduced Amazon sailfin catfish Pterygoplichthys pardalis from the Gombak basin Selangor Malaysia where the suckermouth catfish Hypostomus plecostomus and vermiculated sailfin catfish Pterygoplichthys disjunctivus had been previously reported. Besides selected morphometric and meristic measurements between P. pardalis and P. disjunctivus from the Pusu River Gombak basin were compared. Moreover we also described two body patterns of the P. pardalis collected from the river. The body pattern which does not fit entirely with the known characteristics of P. pardalis or P. disjunctivus is suspected to be a result of hybridization between both species but deeper study should be conducted to confirm this claim.

Abstract

Invasive introduced fish species are well known for their deleterious impacts on aquatic biodiversity and environment. This study provides the first report on the occurrence of introduced Amazon sailfin catfish Pterygoplichthys pardalis from the Gombak basin Selangor Malaysia where the suckermouth catfish Hypostomus plecostomus and vermiculated sailfin catfish Pterygoplichthys disjunctivus had been previously reported. Besides selected morphometric and meristic measurements between P. pardalis and P. disjunctivus from the Pusu River Gombak basin were compared. Moreover we also described two body patterns of the P. pardalis collected from the river. The body pattern which does not fit entirely with the known characteristics of P. pardalis or P. disjunctivus is suspected to be a result of hybridization between both species but deeper study should be conducted to confirm this claim.
