Larve de barbeau fluviatile

Barbel larva, Barbus barbus, 9 days after hatching. Laboratory experiments on the barbel help improve understanding of the characteristics of its life cycle, notably the crucial stages of its development. In particular, research scientists can study its growth thanks to otoliths. They can then target actions to promote the ecological restoration of this species. Indeed, the barbel is a species characteristic of several areas of the Rhône whose life cycle is affected by the numerous hydroelectric developments there.
