 Parasites, particularly crustaceans, are considered as an important limiting factor in the development of
intensified fish culture. The parasitic copepod of the Arabian Gulf fish is poorly known. So, the current
investigation aimed to record the caligid species infecting the rosy goatfish Parupeneus rubescens in the
Arabian Gulf. One copepod species was identified belonged to family Caligidae and labeled as Lepeophtheirus
salmonis Krøyer 1837 depends mainly on its morphological, morphometric, and ultrastructural
characteristics. It is characterized by lacking lunules, the anterior margin of the cephalothorax is not
folded, three-segmented exopod of the fourth leg and longer than the protopod, leg 4 with the middle
terminal claw as long as the inner one, accessory processes on terminal elements II and III of the exopod
of the first leg, a genital complex distinctly wider than being long, and a relatively short abdomen.
Therefore, the present study demonstrated that the rosy goatfish represents a new host for Lepeophtheirus
species and added locality records for this infection.
