Resumo(s)
Based 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.
