title: THE USE OF BIOCHEMICAL METHODS IN THE DIAGNOSIS OF THE CONDITION OF THE PACIFIC OYSTER (CRASSOSTREA GIGAS) FROM THE MARICULTURE FARMS OF THE BLACK SEA
abstract: The physiological state of the pacific oyster (Crassostrea gigas) from mussel and oyster farms of the Black Sea coast of Crimea and the Caucasus in the spring-summer period of 2020-2021 is studied. Physiological and biochemical analysis showed that the overall antioxidant status in the oyster hepatopancreas was higher in the spring season, and in the gills – at the end of the summer season. It was revealed that the adaptive status is characterized by high variability of indicators and depends on
