Importance of Treatment Duration for Praziquantel Used against Larval Digenetic Trematodes in Sunshine Bass |
| |
| Abstract: | Abstract The effectiveness of praziquantel (Droncit) against yellow grubs Clinostomum complanatum and unidentified, encysted, larval trematodes was tested in infected sunshine bass Morone chrysops female × M. saxatilis male. Praziquantel treatments significantly reduced the total number of live grubs in the fish in most treatment regimes tested. Treatment at 0.25 mg/L for 24 h was as effective as one at 8 mg/L for 8 h. Mature dead and dying metacercaria may have released toxins that killed host fish in some treatments. |
