In this study it was shown that dark coloured post‐larvae of Senegalese sole Solea senegalensis , at two different ages, had elevated cortisol concentrations compared with lighter coloured individuals. As melanophore‐stimulating hormone levels were not elevated in dark coloured fish, it is possible that this hormone may not be the main melanotropic hormone involved in stress‐related skin darkening.
