M.; Gerasimov, A.; Barannikova, I.Free and conjugated androgen and progestin levels in the serum of stellate sturgeon (Acipenser stellatus Pallas) males treated with female coelomic fluid, Journal of Applied Ichthyology, 27, 2, 655-659, 2011.0175-8659AUT: ACA00258http://hdl.handle.net/10400.1/3821Based on the supposition that female coelomic fluid contents have a certain chemical influence on sturgeons, blood serum concentrations of free and conjugated testosterone (T), 11-ketotestosterone (11KT), 17,20b,21-trihydroxy-4-pregnen- 3-one (20bS), 17,20b-dihydroxy-4-pregnen-3-one (DHP), 11-desoxycortisol (S) and free progesterone (P4) have been measured by radioimmunoassay (RIA) and enzyme-linked immuno-sorbent assay (ELISA) in stellate sturgeon (Acipenser stellatus Pallas) males treated with female coelomic fluid (CF); CF steroid levels have also been analyzed. After treatment a significant elevation of free 20bS and glucuronidated DHP and S levels and the decrease of free T and KT levels have been observed. The obtained data support the idea that the components of CF may play some part in pheromonal effects for sturgeon reproduction.engjournal article2014-05-08http://dx.doi.org/10.1111/j.1439-0426.2011.01686.x
