The effect of Teflubenzuron on the control of Lernanthropas kroyeri (van Beneden, 1851) (Lernanthropidae) infestations in cultured sea bass, Dicentrarchus labrax (Linnaeus, 1758)
Two different dose groups were formed to evaluate the efficacy of teflubenzuron as a treatment for Lernanthropus kroyeri (van Beneden, 1851) infestation in cultured sea bass Dicentrarchus labrax (L.). Teflubenzuron, coated on commercial feed pellets was administered orally at doses of 0 (control), 10, 20 mg kg-1 biomass day-1 for 7 consecutive days. Fish were randomly sampled and parasites were counted on days 7, 14, 21 and 28, and comparisons were made to untreated control fish. Seawater temperature was 16-18 °C. Treatment with teflubenzuron was not effective against larval and mature stages of L. kroyeri. No differences were observed in growth between the treatment groups and the control group. No mortality was found and adverse drug reactions or palatability problems were not associated with the treatments during the study (p > 0,05)
