The external parasites of the common carp (cyprinus carpio) in technical Institute of Al-Mussayab fish farm
During the period from January 2005 till December 2005, a total of 240 Common carps (Cyprinus carpio) from Technical Institute of AL–Mussayab fish farm were inspected for ectoparasites. The following parasites and their percentage incidences of infection and Mean intensity of infection were recorded...

Zusammenfassung: | During the period from January 2005 till December 2005, a total of 240 Common carps (Cyprinus carpio) from Technical Institute of AL–Mussayab fish farm were inspected for ectoparasites. The following parasites and their percentage incidences of infection and Mean intensity of infection were recorded : Ichthyophthirius multifiliis (% 28.3, 10.5), Trichodina domerguei (% 18.7, 11) , T. cottidarum (% 21.2, 10.9), T. nigrs (% 12, 7.3), Glossatella amoebae (% 11.2, 4), Apiosoma pisciola (% 16.2, 5.3), Dactylogyrus arcutus (% 7.5, 18), D. Minutus (% 1.6, 8.7), D. Achamerowi (% 2.5, 10.3), D. extensus (% 34.3, 6.2), D. solidus (% 11.6, 7.0), D. lipochina (% 5, 8.5), D. amurensis (% 2.9, 5.4), D. carassus (% 12.9, 4.6), Gyrodactylus elegans (% 3.7, 5.7), Ergasilus sieboldi (% 11.8, 7.8) and Lernaea cyprinacea (% 9.5, 6.4). The study revealed abundance of the parasites, which have direct life cycles to occurrence of specific species of parasites with low percentage incidence and mean intensity of infection. Finally the study revealed that some fishes are highly host specific to some parasite in general.
تم خلال المدة من كانون الثاني 2005 و لغاية كانون الأول 2005 فحص 240 سمكة كارب اعتيادي من مزرعة أسماك المعهد التقني في المسيب بحثا عن الطفيليات الخارجية. تم العثور على الطفيليات الآتية مع نسب و شدة ظهورها على التوالي
Ichthyophthirius multifiliis (% 28.3, 10.5), Trichodina domerguei (% 18.7, 11), T. cottidarum (% 21.2, 10.9), T. nigrs (% 12, 7.3), Glossatella amoebae (% 11.2, 4), Apiosoma pisciola (% 16.2, 5.3), Dactylogyrus arcutus (% 7.5, 18), D. minutus (% 1.6, 8.7), D. achamerowi (% 2.5, 10.3), D. extensus (% 34.3, 6.2), D. solidus (% 11.6, 7), D. lipochina (% 5, 8.5), D. amurensis (% 2.9, 5.4), D. carassus (% 12.9, 4.6), Gyrodactylus elegans (%3.7, 5.7) Ergasilus sieboldi (% 11.8, 7.8) and Lernaea cyprinacea (% 9.5, 6.4).
بينت نتائج الدراسة الحالية انتشار الطفيليات من ذوات دورات الحياة المباشرة بنسب و شدة إصابات منخفضة، و أن هناك تخصصا مضيفيا لبعض الطفيليات بصورة عامة. |
