The Common Minnow and the Common Chub

The minnow is very common in highly oxygenated waters. The reason for its presence in high-altitude lakes is that trout fishing is common there. It is used as bait by anglers, which has enabled this species to spread to mountain lakes.

The chub is a fairly large fish, widespread in France. It is an omnivore, meaning it eats everything. In many European countries, particularly in Eastern Europe, it is a major culinary delicacy.
