Description:
Digestive parasites of commercial fish species in the Boojagh wetland were studied in 2002. The fish species included Esox lucius, Cyprinus carpio, Blicca bjoerkna, Tinca tinca, Carassius auratus, Rutilus frisii kutum, Rutilus rutilus and Scardinius erythrophthalmus. Species C. auratus, R. frisii kutum and B. bjoerkna were found free of digestive parasites. The other five species were carrying one of the three digestive parasites Raphidascaris acus, Caryophyllaeus fimbericeps and Asymphylodora tincae. R.acus parasite was isolated from E. lucius and E. erythrophthalmus infecting the species with a mean intensity of 11± 11.15 and 1.8±0.83, a prevalence of 15.4% and 20.2% and a mean abundance of 1.69 and 0.38 respectively. C. carpio and R. rutilus were only infected with C. fimbericeps parasite with a mean intensity of 30.30±46.33 and 5±0, a prevalence of 46.5% and 2.78%, and a mean abundance of 15.48 and 0.14 respectively. The parasite A. tincae was observed only in T.tinca infesting the fish with a mean intensity of 20±0, a prevalence of 25% and mean abundance of 5. Infection of Esox lucius with the parasite A. tincae had been reported from other sites, but this is the first record of Scardinius erythrophthalmus being infected with the parasite. This is also the case for infection of C. carpio with the parasite Caryophyllaeus fimbericeps which was reported before, but found infesting R. rutilus in the Boojagh wetland for the first time.
