Prioritization of fish welfare issues in European salmonid aquaculture using the Delphi method

The European aquacultural sector is undergoing immense growth, and, generally, many more aquatic animals are farmed than land animals. However, the welfare of aquatic animals like fish has received less attention. This study focuses on the two largest contributors to Europe's aquaculture – Atlantic salmon and rainbow trout – farmed in cages in Northern Europe. An extensive literature review was conducted on potential welfare issues.
