Abstract
تمت دراسة ديدان الـ Gyrodactylus spp. (G.) الطفيلية عند 440 سمكة كارب عادي بأعمار 40 يوما" وحتى سنتين، جرى الاعتيان عشوائياً بفاصل 15 يوما" من مزرعة السن خلال الفترة 4-10-2000 حتى 2-10-2001، تم تعيين النوعين G.medius وG.cyprini على الجلد والزعانف غالباً وفي التجويف الفموي والحفرتين الأنفيتين ونادراً على الغلاصم.
بلغ معدل الخمج (الإصابة) بديدان الـ(G.) %17.73 وكان النوع G.medius الأكثر انتشاراً بمعدل 17.5%،
أبدت هذه الطفيليات علاقة بيئية مباشرة مع بعض المؤشرات البيئية خصوصاً الحرارة. سجل هذان النوعان لأول مرة في سوريا.
