Rutilus
Roach ( Rutilus rutilus )
Rutilus (Latin reddish, referring to the coloration ) is a genus of the carp family. Their range extends across Europe, western and northern Asia. These are fish with an elongated, laterally much compressed body whose height increases with advancing age. The small mouth is terminal or below constantly and bears no barbels. The lateral line is bent completely and ventral. Medium to large scales cover the body.
The genus differs from the closely related and very similar appearing species Scardinius by directly above the pelvic fins incipient dorsal fin and between pelvic fins and anal fin rounded, ungekielten belly.
Although it is primarily about freshwater fish, some species can live in brackish water. These populations pull upstream to the spawning season.
