Researchers have identified a new way to determine whether farmed fish were fed fishmeal, offering the aquaculture industry a potential tool to verify feed sources as alternative ingredients become more common.

More than 60 years of plankton data found no assessed pelagic habitats achieved Good Environmental Status, raising concerns about ocean health A new study used six decades of plankton data to assess ocean health in the Northeast Atlantic and found no pelagic habitats met Good Environmental Status.
