Abstract

In the present study, attempts were made to observe the clinical signs of naturally infested Nile tilapia (Oreochromis niloticus) with ectoparasites of the ciliated Trichodina and aquatic leech- ts (Glossiphonia spp.). The prevalence of both parasites were 100% and 30% respectively. The histopathological investigations revealed sever inflammation with inflammatory cells infiltration in skin as well as coagulative necrosis Zenker's necrosis) and oedema of the muscle bundles. Significance of biological control measures using the Bio-clean product (FER Mone-2/ [ A biological mixture of Bacillus thuringien- is var Kurstaki (BTK) and Beauveria bassiana B.b)] as a new method to eradicate such parasites was evaluated. The half lethal concentration (LC-50) was 85 mg/L / 48 hours. The bio- lean product was safe to treat Trichodina spp. Infestation in fish farms at a dose of 25 mg/L. On the other hand, this product was not suitable for treatment of Leeches (Glossiphonia spp.) due to its effective dose (40 mg/L) was narrow safety margin.
