One hundred and fifty common carp (Cyprinus carpio) from district D.I. Khan Khyber Pakhtunkhwa were examined for ectoparasites. The Argulus ectoparasites found were A. foliaceus, A. japonicus, and A. coregoni. Out of 150 fish 17 (11.33%) were infested with ecto parasites. The predominant parasite was A. foliaceus (10%) followed by A. japonicus (8.66%). A. coregoni (6.66%) A. foliaceus is the most abundant ectoparasite in overall study.
