Cover Story: Gonadal steroid hormones—17β-testosterone (17β-T), 11-ketotestosterone (11-KT), and 17β-estradiol (17β-E2)—can modulate normal sexual behaviour in early developed or adult fish, and can also regulate many other critical physiological processes. However, many androgen and anty-androgen active compounds enter the aquatic environment and, even at low concentrations, affect fish, causing a modification of behaviour and sexual or immune function. Therefore, it is important to determine the concentrations of hormones in fish gonads. The goal of this work is to develop a method for the determination of 17β-T, 11-11-KT, and 17β-E2 in sea salmon gonads through the application of high-performance liquid chromatography–mass spectrometry (HPLC-MS) as an analysis technique. This method was applied to determining 17β-T, 11-KT, and 17β-E2 in real samples of female and male sea trout gonads. View this paper
