The survival of the organism depends largely on the timely differentiation of organs and systems in the period of early ontogenesis. At this stage interest is the development of the heart. The objects of study were prelarvae and larvae African catfish (Clariidae). The study revealed that prenticing blood in the early stages of development performed respiratory function. The parts of the heart, the moment of transition of larvae to active feeding were beaten formed. Qualitative analysis of blood cells showed that the examined larvae had signs of hemolytic anemia. In the formation of the heart muscle, there was a steady change of various morphological and physiological stages.
