44 Spawning substrate Sur un fond de gravier ou de cailloutis […] Accessoirement les œufs peuvent être pondus, partiellement au moins, sur les végétaux immergés des rives du cours d'eau. Il est probable que les œufs qui tombent sur un fond vaseux sont perdus, car en aquarium, on constate que des oeufs reposant sur le fond (verre ou sable) ne se développent pas No category Brunet and Hoestlandt, 1972
