چکیده

Argulus japonicus (fish lice) has the greatest economic impact among all ectoparasites infesting cultured and wild fish, and it increases the susceptibility of its host to pathogens. This study aimed to determine the ecology, epidemiology, and histopathological alterations caused by A. japonicus on goldfish (Carassius auratus) in Mosul, Iraq. Three hundred and twenty goldfish were purchased from fish markets and fish stores in Mosul, Iraq. The fish was carefully examined, and A. japonicus were collected manually from the gills, fins, operculum, and entire skin of the fish with the aid of fine forceps. The collected A. japonicus were identified using appropriate entomological keys, and standard pathological procedures were conducted on A. japonicus-infested fish. Of the total number of goldfish examined (320), 197 were infested with A. japonicus, representing 61.56% (95% CI = 56.13–66.72). A total of 2,509 A. japonicus lice were collected from the 197 infested goldfish. The level of infestation ranged between 1 and 25. The mean intensity and abundance values were 12.73 and 7.84, respectively. Different pathological lesions were recorded in the skin and gills of infested goldfish. The infestation of this fish louse caused diverse histological lesions on the skin and gills of the infested goldfish.
