An investigation on fish infection with Diplostomum spathaceum in Amirkalayeh Wetland
Infection with Diplostomum spathaceum parasite is studied in 660 fish specimens from Amirkalaieh wetland of Guilan Province. We collected samples of fish belonging to Esax litchis (78 pieces), Percalluviatilis (163 pieces), Tinca tinca (105 pieces), Cilurtts glanis (64 pieces), Carasshis ouratus 64 pieces, Bliccia bjuericlia (95 pieces) and Rutilus rutilus (91 pieces) since spring to winter 2001. We found the highest infection rate in Rutilus rutihis (63.33%) while the lowest was seen in gialiis (3.13%). The highest and lowest average infection severity were detected in Rutilus rutilus (13.49±10.82), and Tinca tinca .2±0.45), respectively. The highest parasite abundance was related to Rutilus rutihts (7.04±0.93), and the lowest abundance was observed in Tinca tinca (0.06±0.27). Parasite count range was most in Rutilus rutilus (1-49), and least in Tinca tinca (1-2). Statistical analyses revealed significant differences in species, age, sex and season as related to the infection with the parasite.
