​Baltic Sea Herring

Baltic herring (Clupea harengus membras)

The small-sized herring in the inner parts of the Baltic Sea, which is also less fatty than the real Atlantic herring, is considered a distinct subspecies (Clupea harengus membras) (“Baltic herring”), despite the lack of a distinctive genome. The Baltic herring has a specific name in many local languages (Swedish strömming, Finnish silakka, Estonian räim, silk, Livonian siļk, Russian салака, Polish śledź bałtycki, sałaka, Latvian reņģes, Lithuanianstrimelė) and is popularly and in cuisine considered distinct from herring. For example, the Swedish dish surströmming comes from Baltic herring.
