High Welfare Salmon Production Practices

This document is a guide detailing the collaborative process between M&S Food and Scottish Sea Farms in producing high-quality, high-welfare salmon. The partnership, established in 2006, emphasizes control over the salmon's lifecycle, starting from egg selection suited to Scottish marine conditions. The eggs are raised in freshwater hatcheries with closely monitored welfare factors. The fish are fed a bespoke diet tailored to their nutritional needs while minimizing the use of finite marine ingredients. The guide outlines the advanced fish husbandry practices employed at sea, adhering to RSPCA Assured welfare standards. It describes the roles of in-house veterinarians and biologists in monitoring health and preventing threats. The document also highlights recent innovations, such as the use of freshwater baths and cleaner fish for pest control, and the trial of growing seaweed for shelter. Furthermore, it discusses the consolidation of farming estates for improved conditions and operational efficiencies, culminating in humane harvesting practices recognized for their contribution to fish welfare.
