| Abstract | ||||
| In the present study, the clinical signs of naturally Infested Ctenopharyngodon idella with Ichthyoboda necator and Capillaria spp. Larval stage and Naturally infested Oreochromis niloticus with ectoparasites of the ciliated Trichodina and mono-Genetic trematode Gyrodactylus spp. Were observed and recorded. The prevalence of infection in C. idella with I. necator was 100% And Capillaria larvae was 50%. Moreover, the Prevalence of infection in O. niloticus with mixed infestation of Trichodina and Gyrodactylus spp. Were 100%. Microbial antiparasitic product (Age-Rin) was tested for in vivo activity against a natuRal infestation of C. idella and O. niloticus by the Flagellated I. necator and larval stage of capillaria Spp. And mixed infestation of Trichodina spp. And Gyrodactylus spp, respectively by bathing fishes in different concentrations and variable exposure Times. Complete elimination of I. necator and capillaria Larvae in all C. idella fish was achieved by 1000 ppm/1 h. and 500 ppm/2 h of Agerin. Trichodina Spp. Were also completely eradicated at 500 ppm/ 1 hr, 1000 ppm/2h and indefinite use of 100 ppm with naturally infested O. niloticus. The biological product Agerin was not toxic to Treat ectoparasite protozoan in C idella (LC50 6800 ppm/ 48 hrs) and O. niloticus (LC50 6200 Ppm/ 48 hrs). On the other hand, this product was not suitable for treatments of gyrodactylus spp. | ||||
