First Look into the Use of Fish Scales as a Medium for Multi-Hormone Stress Analyses

Recent efforts have provided convincing evidence for the use of fish scale cortisol concentration in assessment long-term stress fishes. However, alone is not sufficient to fully describe this state stress. Dehydroepiandrosterone (DHEA) an androgen with actions that oppose those cortisol. The means by which DHEA negates effects occurs part via changes metabolism cortisone. quantitation cortisol, and cortisone could therefore provide a more comprehensive overall status physiological As yet be quantified within scale, our first objective was ensure sample processing protocol applicable DHEA. Following this, we induced goldfish (Carassius auratus). Some degree elevation all hormones observed stressed scales. Additionally, were significantly elevated serum comparison controls while undetectable either group. Overall, these results suggest scales appropriate medium fishes relevant steroid hormones.
