Özet:

 


There was a decrease in artificial spawning
performance of hatchery-reared cyprinid brooders in the spring of 2016 in an
Egyptian hatchery. In this study, cyprinid brooders and fingerlings were
clinically examined in situ, which showed that they were affected with
leechiosis. Hemiclepsis marginata were identified as a causative agent of
leechiosis. The prevalence of leechiosis was highest in silver carp (Hypophthalmichthys
molitrix) brooders and common carp (Cyprinus carpio) fingerlings. The infested
brooders and fingerlings showed red to white marks, severe hemorrhages, and
dark contracted worms on their skin. The impact of leechiosis on
semi-artificial spawning performance and hematological parameters of H.
molitrix brooders was evaluated by determining the eggs weight, fertility,
hatching percentage and the complete blood picture. Leechiosis had a
significant impact on eggs weight, fertility, and hatching percentage.
Microcytic hypochromic anemia, leukocytosis, lymphopenia, and heterophilia were
recorded in the infested brooders. Regarding the association between leechiosis
and stress response, the total antioxidant enzymes were found to be
significantly decreased, whereas malondialdehyde levels were increased in the
infested brooders compared with those in control samples. Under the
experimental condition, leechiosis could be controlled among C. carpio
fingerlings using trichlorfon, after which normal hematological parameters were
recorded for the treated C. carpio fingerlings. Regarding the field conditions,
trichlorfon could successfully control leechiosis in H. molitrix brooders and
C. carpio fingerlings.
