title: Ecto-ATPases, morphometry and heat production activity of erythrocytes of cartilaginous and teleost fishes of the Black Sea
abstract: The activity of ecto-ATPase and the size characteristics of erythrocytes in two species of cartilaginous and ten species of bony ﬁshes, as well as the heat-production activity of the erythrocyte suspension in Scorpaena porcus and Raja clavata were studied. It was shown that the activity of ecto-ATPase of red blood cells (RBC) between cartilaginous ﬁshes diﬀers by 1.5 times and is 3.1 nmol Fn/min/μl RBC in Raja clavata, and 2.1 nmol Fn/min/μl RBC in Dasyatis pastinaca. Erythrocytes of teleost ﬁsh
