features

The Tiber barbel can be up to 70 centimeters long with a maximum weight of six kilograms. It has 58-77 scales along the sideline. Tiber barbs have a spindle-shaped body and a lower mouth with four barbels on the upper lip. The pharynx are arranged in three rows. In terms of color, it is similar to the dog barbel ( Barbus meridionalis ). Tiber barbs are lighter and are mostly dotted.

Occurrence

The Tiber barbel occurs in the Adriatic basin from Tronto to Krka . It is also widespread in the Soča and Isonzo rivers in Slovenia , Croatia and in some Swiss waters . It was introduced into central Italian rivers that flow into the Tyrrhenian Sea . It is very widespread, often in the Po and other northern Italian rivers.

Way of life

The Tiber barbel reaches a relatively old age. It mostly lives in fast-flowing and oxygen-rich waters in the mountain regions, but also lives in lowland rivers. It is also found in some lakes. It feeds on benthic small animals, fry, juvenile fish and algae. The spawning season takes place in the months of April to July, with the animals preferring to spawn on gravel.

Hazard and protection

The Tiber barbel is regionally threatened by overfishing . In the middle reaches of the Po, their population has declined due to the proliferation of catfish ( Silurus glanis ) and river barbel ( Barbus barbus ).

The Tiber barbel is listed by the European Union in Appendix II of the Habitats Directive and is therefore considered a type of community interest, for whose preservation special protection areas must be designated by the member states.

Economical meaning

It has been introduced into numerous Italian waters as a sport fish.
