Herring organs damaged by acidified seawater

Ocean acidification could damage the organs of Atlantic herring, as well as slow their growth and development, recent experiments show. It adds to the list of pressures currently threatening this commercially important species, including over-fishing and marine pollution. (…)

The study investigated acidification’s likely effects on Atlantic herring (Clupea harengus), which has a range stretching from the east coast of North America to the west coast of Europe and the Baltic Sea. The Baltic Sea suffers with eutrophication, which aggravates acidification. Acidification is therefore expected to be particularly severe in the Baltic, an important spawning ground for this heavily-fished species. In fact, pH values of 7.2 have already been recorded in parts of the Baltic. (…)
