Variation in Polycyclic Aromatic Hydrocarbon Contamination Between Native and Introduced Species of Fishes of Pallikaranai Wetland, Chennai, Tamil Nadu, India.

The impacts of invasive fish species on recipient communities are mostly considered a threat to the biodiversity of freshwater systems. A characteristic of introduced species turning invasive is their higher tolerance to environmental stressors. To understand if non-native fishes in Pallikaranai wetland, Tamil Nadu, India, are more tolerant to anthropogenic pressures in the Wetland, we assessed the variation in Polycyclic Aromatic Hydrocarbon contamination between introduced and native fish species.
