Slaughter directly from farmed cages has clear advantages with regard to the salmon's welfare and quality. It is probable that the Norwegian Food Safety Authority will approve this method if the hygienic conditions are good enough.
All treatment of live salmon (penetration, hauling, pumping, cooling, etc.) entails a risk of poor welfare. In addition, this leads to repeated physical stresses that can result in fatigue (manifested by low muscle pH), emptying the swim bladder and emptying the salmon's energy stores (ATP, glycogen and reduced buffer capacity post mortem). Together, a traditional slaughter logistics leads to a salmon that is more or less exhausted and that enters the rigor mortis after a short time (5-10 hours). For salmon slaughtered gently directly from farmed cages, the pre-rigor time will be about 30 hours. In addition, the rigor mortis will be weak.
The project is a continuation of the project ""Killing of farmed salmon on a boat: Phase 1"" . Phase 1 was carried out on a well boat while phase 2 was carried out on a purse seine vessel, M / K ""Sørfold"". The experiments in phase 2 were partly carried out when the vessel was stationed in Ryfylke from July 2007 (the experiments took place in August and September) and at the end of the year when the vessel was stationed at Marine Harvest's facility on Hærøy.
Goal: to test killing and bleeding on a boat at almost full industrial scale, and to form the basis for reorganization of all slaughter at Marine Harvest, region South.
