Vulnerable species – Risk of extinction
Gregarious lacustrine forms and anadromous estuarine forms, rarely in full saltwater. Feeds on planktonic crustaceans, or larger benthic (waterfloor level) crustaceans in brackish water. Movement in water column as a function of zooplankton repartition. Likely to benefit from environmental regulations.
Europe: Native to Lake Bourget (France) and Geneva (Switzerland, France). Has been stocked into many other places in Europe outside its native range. Asia: introduced to Iran.
