A non‐invasive stress assay based upon measurement of free cortisol released into the water by rainbow trout

Ellis, T., James, J. D., Stewart, C., Scott, A. P.·2004·Journal of Fish Biology

Abstract

A procedure previously used for sex steroids was adapted to extract free cortisol and cortisone from water samples taken from rainbow trout Oncorhynchus mykiss tanks. Both corticosteroids could be readily detected by radioimmunoassay (RIA), with cortisol being predominant. All stages of the sampling, extraction and RIA procedure were validated for cortisol. An intermittent problem with poor replication was traced to the use of diethyl ether during the extraction procedure, and was overcome by the use of ethyl acetate. Other modifications were also introduced to speed up the procedure. The concentration and time course of release of both corticosteroids were shown to be related to the degree of stress that the fish had been subjected to. It was confirmed that cortisol concentrations in water and estimated cortisol release rates increased in response to handling stress, and that both were correlated with plasma cortisol concentrations. The potential for using water cortisol concentration and release rates to assess the primary stress response of fishes as a non‐invasive alternative to blood sampling is discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
