Fig. 5. Variations in the plasma cortisol concentrations in the blood plasma of the tiger puffer, Takifugu rubripes during 48 hrs of various clove oil dose and temperature in anaesthetic groups. Values are means±SE of triplicate experiments (n=50). a: 20℃; b: 24℃; c: 28℃. Actually n=96 for each experiment because the means and SE were calculated separately for each group. Different letters on error bars are significantly different among elapsed time in anaesthesia groups (p<0.05).
