How to recognize the schneider ?

The schneider is two-colored with a very colorful and contrasting body of green and silver. Its silhouette is between that of the bleak and the bream. It has a tall and slender body. It has a slender head with a "terminal" mouth.

Its wavy lateral line is strongly curved downward, accentuated with two rows of black spots and a dark stripe.

Juveniles can be identified early by their thin black line along the back.

Sexual dimorphism

Few differences except during the breeding season, when the egg-laden females have a well-rounded belly.

The schneider is a fish living in schools that naturally resides at mid-depth and close to the surface. It is a species with a lively temperament. This species is very active by nature and enjoys large spaces.

It is capable of undertaking long migrations in early and especially late summer and does not hesitate to use fish passages in large numbers. Its potential predators are trout, chub, perch, and zander.

Generally, it is an independent fish that pays little attention to other species. However, it may show some signs of aggression towards its own kind.

Reproduction

The schneider is an oviparous fish that spawns on pebbles and gravel in moderate currents. The eggs are briefly introduced into the bottom to which they adhere.

Spawning, which is multiple, begins in April as soon as the water temperature exceeds 12°C and continues until June with a temperature of 18°C.

Biotope presentation

The species particularly favors clear waters with strong currents and rapids in the barbel zone, but can also be found in the cool waters of some alpine lakes.

Primarily insectivorous, it often feeds in open water on organisms carried by the current. It may supplement its diet with algae (diatoms, chlorophytes, etc.). The substrate is generally composed of pebbles and rocks.
