A new study into salmon feeding paths

The University of Southampton with funding by the Department for Environment, Food and Rural Affairs (DEFRA) has discovered a new method of tracking where Atlantic salmon feed in the ocean. The study has shown that the marine location can be recovered from the chemistry of  the fish scales.

Another surprising fact has show that British salmon from different rivers migrate to different places to feed and may respond differently to environmental change. A paper published recently in the Scientific Reports shows that fish carry natural records of feeding location hidden in the chemistry of their scales.

Using this idea, the Southampton team, working with scientists from the Centre for Environment, Fisheries and Aquaculture Science (Cefas), the Game and Wildlife Conservation Trust (GWCT) and the National Oceanography Centre (NOC). Read more ...
