Abstract

Salinity fluctuations can impose significant stress on aquatic organisms. This study investigated the short-term effects of a 10 ppt salinity drop (from 26 ppt to 15 ppt) on Oryzias latipes. After 24 h of exposure, brain, liver, and gill tissues were analyzed for ATP concentration, total protein content, and acetylcholinesterase activity. Results showed significant ATP depletion and increased protein levels in the brain, suggesting elevated metabolic demand under osmotic stress. Liver and gill tissues exhibited no significant biochemical changes. These findings indicate that acute salinity changes primarily affect brain metabolism, while other tissues remain relatively stable. The study provides insights into tissue-specific osmoregulatory responses in euryhaline fish.
