Abstract

aim of investigating the effect of salinity changes on the activity of liver enzymes alanine aminotransferase (ALT), aspartate transferase (AST), alkaline phosphatase (ALP) and the biomarker malondialdehyde (MDA) in gray mullet. , fish samples after acclimatization were studied in treatments of 28, 34, 50 and control (36.5) psu in three periods of 7, 14 and 21 days. malondialdehyde biomarker was the highest on the 7th and 14th day in 50 salinity treatment, but the highest value was recorded on the 21st day in 34 salinity. The statistical test showed a significant difference between days and treatments (P<0.05). Alanine aminotransferase had the highest value on the 7th day at 50 salinity, on the 14th day at the control and on the 21st day at 28 salinity, and the difference between the data was significant. In the measurement of aspartate transferase enzyme on the seventh and twenty-first days of the control treatment and on the seventh day of 34 salinity, they had the highest amount. . Alkaline phosphatase enzyme had the highest value on the 7th day at 34 salinity, on the 14th day at 28 salinity and on the 21st day at 50 salinity,
