Abstract
Caspian Sea has oil treasure as well as fisheries resources One the most precious resources of fisheries are sturgeons Crude oil is a very dangerous pollutant of water ecosystems which are in possession of oil resources In the present study juveniles beluga were exposed to four indirect doses 0 10 100 500 and 1000 ppm of watersoluble fraction WSF of crude oil for 0 h 48 h and 7 days The results showed that after 48 h of exposure all biochemical indices glucose triglyceride calcium and protein significantly increased P ≤ 005 Furthermore all biochemical indices showed significantly elevation after exposure to WSF of oil for 7 days P ≤ 001 Among enzymatic parameters in both sampling times alkaline phosphatase decreased and the aminotransferase and alanine aminotransferase increased along with different doses of WSF of crude oil exposure
