Recent evidence of a functionally extirpated ecotype of herring, Clupea harengus (Actinopterygii, Clupeiformes, Clupeidae), in the southern Stockholm Archipelago, Baltic Sea
The fall spawning ecotype of the herring, Clupea harengus Linnaeus, 1758, is considered functionally extirpated in the Baltic Proper. Once the dominant ecotype in fisheries landings of herring, few ob...
