Cortisol production over time by European sea bass larvae reared at low or normal (Control) density and exposed to a gradual increase of temperature over 5 days. (A) Mean cortisol (ng/L) and (B) Mean cortisol produced per fish (pg/L/fish) represented by points (mean + SE), released into the water by developing larvae (from 13 to 28 dph) exposed to a gradual increase of temperature from 16 to 19 °C (0.5 °C per day from 17 dph, represented by red rectangles of increasing intensities). “*” indicates significant differences in cortisol release during the increases of temperature between the low-density treatment and the to control (p < 0.05).
