Due to the increasing number of fishes being farmed for human consumption, more and more academic interest is being directed towards farmed fish neurobiology and welfare.
Concerns for the welfare farmed fishes, as well as those being used as replacements for mammalian biomedical models in research, are on the rise. In this study, a group of researchers from Northern Europe looked at how the brains of physically underdeveloped salmon react to stress.
