Learning capabilities of a small tropical pelagic fish, the thread herring (Opisthonema oglinum), were studied under experimental conditions. The conditioning consisted of associating a series of three sound pulses with a stress (hoisting a horizontal rigid net from the bottom to the surface). Individual sensibility and school stability measures indicate that fish can be stress-conditioned. Futhermore, these conditioned fish, when mixed with non conditioned fish ("naive" fish), can lead reactions in a school. The results and their influence on fishing are discussed. (Résumé d'auteur)
