About

The European chub is one of the most common fish in the foothill and plain sections of the Carpathian rivers. It lives in the basins of the Tisza, Prut, Dniester, and San rivers, and moves upstream until the current becomes too turbulent and the water too cold. It is often found alongside the marble trout, grayling, and trout at the boundary of the mountain and foothill parts of the river.

The European chub is easily recognizable by its large, broad head with a big mouth, thick, almost cylindrical body, and large scales with a dark fringe, giving its sides a net-like appearance. The back is dark, the sides are silvery, and the ventral and anal fins are reddish.

The European chub is omnivorous: it eats aquatic insects and their larvae, crayfish, frogs, small fish, as well as insects, berries, and seeds that fall into the water from riverside bushes. Large fish become true predators. Spawning occurs in spring, mainly in May–June, in fast sections with a stony bottom.

In summer, schools of European chub stay under overhanging branches and near snags, carefully picking up everything that falls onto the water. The fish is skittish: it sees anglers on the shore from a distance.

The European chub is not listed in the Red Book of Ukraine; it is caught according to the general Rules of Amateur Fishing.
