What is Lack of species‐specific primer effects of odours from female Atlantic salmon, Salmo salar , and brown trout, Salmo trutta about?

We exposed, in two successive spawning seasons, individually placed precocious male Atlantic salmon (__Salmo salar__) and brown trout (__Salmo trutta__) parr to odour stimuli (ovarian fluid and urine mix) from ovulated conspecific or heterospecific anadromous females. Atlantic salmon parr had significantly higher plasma concentrations of the hormones 17α,20β‐dihydroxy‐4‐pregnen‐3‐one (17,20β‐P), 11‐ketotestosterone (11‐KT) and testosterone (T) after exposure to odours from conspecific females or from brown trout females compared to parr exposed to a control solution (0.9% NaCl). We did not observe any significant differences between the hormone levels in salmon parr exposed to the two female odours. The salmon parr exposed to conspecific odours had significantly higher volumes of strippable milt compared to the controls, but we did not find any significant differences when comparing the effect of the two female odours. Brown trout parr had significantly higher plasma 17,20β‐P levels following exposure to heterospecific female odours compared to control males, but there was no significant difference between males exposed to the different female odours. We did not observe any signifi
