THE DISPERSAL ON INTESTINAL PARASITES IN FISH IN AL-RUTBA DAM

Abstract

Abstract: 122 Samples of four fish species Carb, Hummri, Shaboot and Shilig were gathered and dissected reaching their digestives canals and body colem . Parasites found were classified and found to be related to five different species which were: Contracaecum sp. , Aspidogasterlimacoides,Proteocephalusosculatus, Spiroxys sp. , Bothriecephalusopsariichthydis.The total infestation percent with parasites was 67.2 % , the highest infestation precent 70.9 % by Contracaecumsp.and the lowest was 22.5 % by Spiroxys sp. in Shilig type of fish. The most critical infestation degree was (8.07) byProteocephalusosculatus. in Shilig and the lowest degree of infestation was (0.5) by Bothriecephalusopsariichthydis. in Carb fish. Seasonal fluctuations had an effect on the infestation percent It was recorded that the highest infestation percent was 73.8 % during autumn.
