Title: INVESTIGATIONS ON THE INFESTATION IN SOME GILL PROTOSOOSYS IN JUVENILE CYPRINIDS
Abstract: The investigations conducted on a sample of 68 juvenile cyprinids (33 crucian carp, 20 carp and 15 silver carp), breed and maintained in a semi development fishery, type household from Gherla area, Cluj, taken in April-May 2011, regarding the incidence and the intensity of parasitism in some localized protosoosys gill (criptobiosys, ihtioftiriosys and trichodiniosys), shows some different aspects . The incidence of parasitism in criptobiosys has low values in juvenile crucian carp and silver carp (9.0% and 6.6%) and medium (20%) in juvenile carp. Instead, in the intensity level of parasitism in juvenile crucian carp and silver carp dominate low infestations (66.6% and 100%) and at the juvenile carp average infestations (50%). Extensity of ihtioftiriosys had highest values in juvenile silver carp (26.6%), followed by juvenile crucian carp (21.1%) and minimum values for juvenile carp (10.0%). At crucian carp dominate the medium infestation (50.0 %). The incidence of Trichodiniosys has elevated high values for crucian carp (48.4%) and average values for silver carp and carp (40.0% and 35.0%). Different aspects of parasitism intensity appear namely, at the crucian carp and silver carp juvenile carp dominate low infestations (71.5% and 66.6%) and in juvenile carp dominate the medium and heavy infestations (50.0%).
