New study documents evolution of fast-growing, fish-eating herring in Baltic Sea

Atlantic and Baltic herring are typical plankton-eating fish of central importance for the northern Atlantic Ocean and Baltic Sea ecosystems. A new study published in Nature Communications led by scientists from Uppsala University (Sweden) documents the discovery of the evolution of genetically distinct, fish-eating herring in the Baltic Sea, a young water body that has only existed since the end of the last glaciation.
