Productivity and recovery of forage fish under climate change and fishing: North Sea sandeel as a case study
Abstract Forage fish occupy a central position in marine food‐webs worldwide by mediating the transfer of energy and organic matter from lower to higher trophic levels. The lesser sandeel ( Ammodytes marinus ) is one of the ecologically and economically most important forage fish species in the Nort...
