Channel catfish Ictalurus punctatus with infections of yellow grubs Clinostomum marginatum and eye flukes Diplostomum spathaceum were treated with 2 mg Droncit (praziquantel)/L in a water bath for 2 and 4 h. At the time of treatment, 80% of the fish had visible yellow grubs and 70% had opaque eyes. Fourteen days after treatment, 40.1% of the yellow grubs in the 2‐h treatment were dead. No grubs were dead in the 4‐h treatment; however, the number of yellow grubs was reduced in the treated fish. No dead eye flukes were seen in untreated fish after 14 d, but 59.2 and 44.4% of eye flukes in the 2‐ and 4‐h treatments, respectively, were dead. At 21 d, the percentages of dead eye flukes were 86% (2 h) and 90.1% (4 h). Droncit had limited effect on yellow grubs in channel catfish, but the chemical had a beneficial effect of reducing numbers of eye flukes.
