Synopsis
The behaviour of migrating glass eels towards different concentrations of seven bile salts and taurine was investigated by binary-choice experiments. All substances attracted glass eels when presented at concentrations below 10−10M. Glycocholate, taurodeoxycholate and taurine remained attractive at higher concentrations, while taurocholate, cholate, deoxycholate, glycochenodeoxycholate and taurochenodeoxycholate became repellent. A role of bile salts in grouping and orientation behaviour of glass eels is discussed.
