The analysis of steroid hormones 17β-estradiol, testosterone and 11-ketotestosterone in fish
plasma provide insight into fish reproductive behavior and development. Typically, steroid …

Commercially available enzyme immunoassay (EIA) kits were validated for measuring
steroid hormone concentrations in blood plasma from three fish species: the orange …

Quantification of steroid hormones in fish is an important step for toxicology and
endocrinology studies. Among the hormone analysis techniques, liquid chromatography …

A capillary separation method that incorporates pH‐mediated stacking is employed for the
simultaneous determination of circulating steroid hormones in plasma from Perca flavescens …

Many aquatic species, such as teleosts, release into the water and detect multiple bioactive
substances to assist in schooling, migration, alarm reactions, and to stimulate behavioral …

A reliable and rapid technique for the measurement of estradiol-17β, testosterone,
progesterone, 17α-hydroxyprogesterone, 17α, 20β-dihydroxy-4-pregnen-3-one, and cortisol …

This article describes the development and validation of a sensitive LC–MSMS method for
