Bile acids have been implicated as chemical signals in spawning behaviour of lake char (Salvelinus namaycush). In this study, we investigated olfactory responses of lake char to bile acids by using the electro-olfactogram recording. Lake char detected 9 out of 38 bile acids tested at thresholds 0.02–0.5 nM. The most stimulatory included chenodeoxycholic acid, cholic acid, taurochenodeoxycholic acid, taurocholic acid, and taurolithocholic acid 3α-sulphate. Structure–activity analysis indicated… CONTINUE READING
