| Abstract |
Sanguinicola species are becoming nowadays important fish parasites as the aquaculture industry continues to expand .In this study, two cultured freshwater fish species namely Cyprinus carpio and Clarias gariepinus were examined for blood flukes (Sanguinicola). Examination of gills, heart and kidneys revealed the presence of live adult flukes in heart and kidneys, and eggs containing different miracidia stages in gill vascular structures. Examination of C. carpio revealed the infestation of 20% with Sanguinicola inermis (Plehn, 1905). On the other hand, examination of C. gariepinus revealed the infestation of 80% with Sanguinicola dentate (Paperna, 1964). The clinical examination of infested fishes showed the presence of ascites as the most obvious sign ofdisease and/ or emaciated appearance.
Effect of Sanguinicoliosis on the two fish species was evaluated through holding blood haemogram: haemoglobin concentration, erythrocytic count, total leucocytic count, and serum electrophoretic analysis. In addition, the UV sorbance frequency curve of serum protein was held. Species variation proved more effectivness with C. gariepinus where the haemoglobin and total protein levels highly significant decreased while the same parameters decreased in C. carpio non significantly. The total leucocytic count registered highly significant increase in both species resulting in raising antibodies level. On the contrary, the use of serum electrophoretic analysis proved that infestation of C. carpio was more evident where albumin fraction decreased in both species .The picture for the alpha, beta and gamma globulins was highly significant drop for the first two and highly significant increase with the third being the fish defence line. The use of UV Absorbance protein frequency curve applied for the first time approved the obtained data.
A treatment trial was held using Droncit 10 mg \L for 1 hour\ 3 days. Fish were completely free from flukes and eggs. Blood analysis revealed a slight increase in haemoglobin level and RBCs count, the TP and WBCs count remained high.
