| Abstract | ||||
| The hemostasis system is designed to ensure the integrity of the internal environment of the body and bleeding control and maintain the liquid state of blood in the vasculature. Clinicodiagnostic characterization of clotting in different fish species contains incomplete and scarce information in modern biological science. The data obtained revealed some issues of functioning of the ancient mechanism of blood clotting in these animals in both evolutionary and veterinary aspects. Thus, a comparative study was conducted on the functional state of plasma hemostasis in some commercial fish; namely, cartilaginous ganoids sturgeon (Acipenser baerii), hybrid of sterlet (Acipenser ruthenus), starred sturgeon (Acipenser stellatus), bony – common carp (Cyprinus carpio) and the tilapia, Oreochromis niloticus. The following coagulogram parameter changes were addressed: thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time (APTT), the concentration of fibrinogen, and soluble fibrin monomer complexes (SFMC). It is assumed that the functioning of the plasma hemostasis system has species specificity regardless of stress resistance, especially in commercial fish at different evolutionary stages. Hence, species-specific characteristics of fish clotting were determined. Activation by the common and extrinsic pathways was several times faster in cartilaginous ganoids (reduced TT by 17.8-26 times, PT by 1.9-2.6 times, reduced fibrinogen concentration by 4.8-6.11 times) than in both the species of bony fish. The hemostasis, with activation of the intrinsic pathway (APTT), was faster in the hybrid and the tilapia by 20.6-16.8 times compared to that in sturgeon, and by 2.8 and 2.2 times compared to carp. The SFMC content in all fish was (1.3-4.3 times) higher than that noted in dogs and 2.5-8.3 times higher than the SFMC content in humans. But, it was lower (1.0-2.4 times) compared to that recorded in cattle. The highest/lowest values of SFMCs were detected in carp and the hybrid of A. ruthenus and A. stellatus, respectively. | ||||
