Muscle pH, rigor mortis and blood variables in Atlantic salmon transported in two types of well-boat
Two systems for transporting live salmon ( Salmo salar ) were compared in terms of their effects on blood variables, muscle pH and rigor index: an 'open system' well-boat with recirculated sea water at 13.5°C and a stocking density of 107 kg/m3 during an eight-hour journey, and a 'clo...
