Causal analysis of escape of Atlantic salmon and rainbow trout from Norwegian fish farms during 2010–2018
Farmed fish escaping into the wild and other environmental concerns have curbed the expansion of the Norwegian aquaculture industry. Detailed knowledge of both direct and underlying causes of previous escape episodes is crucial to ensure successful development of new technology and targeted safety-m...
