Advancement of non-invasive detection methods of cortisol in teleost fish.

Abstract

This project aims to increase our understanding of stress responses and the measurement of stress in teleost fish. Knowledge gaps in the literature were identified through critically reviewing the literature surrounding teleost fish primary and secondary stress response in relation to the stressor of water motion. State-of-the-art techniques to measure cortisol were evaluated for measuring the stress response in marine fish as well as determining the best way to measure cortisol for unbiased sampling. Together these formulated three primary avenues of research:
1) Assessing cortisol concentration from different matrices
2) Developing water as a matric and
3) Comparisons of the ELISA and MS methodologies.

Thesis is embargoed until 31 July 2026.
