Abstract

We compared the ability of urine and ovarian fluid from female Atlantic salmon (Salmo salar) to stimulate increase in plasma concentrations of sex steroid hormones in mature conspecific male parr (priming effect of the stimuli). We also tested the hypothesis that prostaglandin F-2 alpha (PGF(2 alpha)) may act as a priming pheromone in the tested stimulants. Individual males of salmon parr were exposed to female urine, ovarian fluid, urine-ovarian fluid mix, or PGF(2 alpha) Plasma concentrations of the sex steroids of 17,20 beta -dihydroxy-4-pregnen-3-one (17,20 beta -P) were higher in males exposed to urine, ovarian fluids, and PGF(2 alpha), compared to control males. PGF(2 alpha). and a mixture of urine and ovarian fluid also gave increased concentrations of 11-ketotestosterone (11-KT). Concentrations of PGF(2 alpha) were higher in ovarian fluids than in urine. A behavior test with mature male part in a fluviarium showed neither attraction to nor avoidance of0.1 nM PGF(2 alpha), but plasma levels of 17,20 beta -P were significantlyhigher in exposed males compared to controls.
