Development scientific bases of rational technology fish cultivation is important for control its physiological status . This work aim was the comparative blood evaluation of juvenile catfishes Silurus glanis and Clarias gariepinus by hematological, cytochemical and biochemical indicators . Cultivation and collecting samples was produced from the fish farm «Kirya» from the 2nd fish-breeding zone for studding wels catfishes and from the recirculating water aquaculture system (RAS) of Russian State Agrarian University — Moscow Agricultural Academy K . A . Timiryazev for studding North African catfishes . Physiological differences were identified: erythropoiesis of wels catfishes are more intensive, because mature erythrocytes quantity is small; leukocyte formula of North African catfishes contains myeloblasts, there are the percentage of segmented neutrophils three times more and the percentage of monocytes six times less relatively wels catfishes . North African catfishes have 44% protein and 22% albumin higher, alanine aminotransferase activity was 1 .7 times less . Serum of North African catfishes has high values of amylase twice times more that due to the functioning characteristics of the pancreas, because it was loaded intensive feeding in the RAS and high density of fish breeding . The reported parameters show intensive metabolism of North African catfishes due to more intensive cultivation technology in the RAS and innate qualities . The identified values of physiological parameters catfishes will be useful in evaluating its status in breeding and selecting for future work
