Esmaeli, F. | Abbasi, S.
In summer 1994, 30 grass carp (Ctenopharyngodon idella) were caught from a pond culture and blood sampling was done, while the fish were alive, for ichthyohaernatologicall examination. The fish and blood were brought to the laboratory, the digestive tract and internal organs of fish were examined for parasitological investigation. Eleven fishes were infected by a tape worm (Bothriocephalus) seriously. Number of parasites in intestine of each fish specimen was between 70 -80 and they cause intestinal obstipation. Amount of haemoglobin, haematocrit value and erythrocyte in infected fishes was lower than healthy fishes.
