The paper presents a number of morpho-physiological characteristics of the sea ruff (Scorpaena porcus Linnaeus, 1758) from two bays of the Black Sea, different in terms of pollution, It was revealed that the liver index of S. porcus males from Laspi is higher than the liver index in fish from Quarantine Bay. There were no differences in the IP of females. Gonadosomatic index in males and females S. porcus does not differ significantly from the two areas. The Fulton fatness coefficient in females is 6.8% higher in individuals from Laspi Bay. There were no significant differences in the values of the Fulton fatness coefficient in males. The paper presents also size-mass and some morpho-physiological characteristics of the common ruff (Gymnocephalus cernuus, Linnaeus, 1758), caught in the shallow part of the eastern part of the Gulf of Finland in July In 2023. There were no significant differences in size, weight and fatness in individuals of the common ruff. The size and mass characteristics of the ruff ...
