A review of factors affecting the welfare of Atlantic salmon (Salmo salar)
Abstract In the expanding salmon industry, many farmers use production methods that could result in poor welfare of the fish at various points of their lifecycle. We have reviewed methods used for producing salmon for food with the aim of identifying and drawing attention to factors likely to affect...
