Open Access Treatment of Argulus sp. Infestation of River Frogs

Download Article:
Ten river frog tadpoles (Rana hecksheri) were collected from Pointsett State Park in South Carolina in April 1995. They were housed together in a tank at the North Carolina Zoological Park. Although no skin lesions were evident at collection, skin scrapings performed 4 weeks later revealed numerous immature and adult Argulus sp. on the tails and dorsal trunks of many of the tadpoles. The adult parasites were removed manually, and the tadpoles were treated with lufenuron (15 mg/l; Program, Novartis Animal Health, Greensboro, N.C.) and sodium chloride (3 g/l) in the tank water for 3 weeks. A single immature Argulus was found on a skin scraping on day 2 of treatment, and no parasites were seen thereafter on skin scrapings obtained through day 28 after the initiation of treatment. Metamorphosis occurred in all tadpoles within 4 weeks of initiating treatment. No deleterious effects of the treatment were noted.
