Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 3 - 4; Radios blandos dorsales (total) : 12 - 14; Espinas anales: 3 - 4; Radios blandos anales: 16 - 21. This species is distinguished from its congeners entering the freshwater in Mediterranean basin by the following characters: gill rakers 106-128; teeth on palatine and vomer well-developed, especially in juveniles (Ref. 59043).
Landlocked, lacustrine, pelagic, in upper water layers during summer and descending to deeper layers in winter. It spawns at 1-2 years, near shores above gravel or coarse sand, with most individuals spawning more than one season. Spawning starts when temperature reach about 19-20°C, in July to August (Ref. 59043). Adults form schools in the epilimnion during summer and tend to congregate in shallow waters near shores. They feed on plankton (cladocerans and copepods) and small fishes (Ref. 10545, 59043). It is threatened by water abstraction and pollution (Ref. 26100).
Deposits eggs near the shore where the sediment consists of gravel or coarse sand (Ref. 10545). Most individuals spawn in more than one season (Ref. 59043).
