The experimental design for measuring serum cortisol level in Epinephalus fuscoguttatus exposed to different salinities. Two hundred fingerlings were acclimatized in a 500 L tank with 31 ppt salinity for 2 weeks. After acclimatization, 10 fish were introduced into each tank containing 22 L seawater adjusted at different salinities of 31 ppt, 25 ppt, 20 ppt, 15 ppt, 10 ppt and 5 ppt with triplicates. Blood sampling was done after 5, 30, 60 and 120 min. followed by observation for survival percentage for two weeks.
