Farmed Atlantic cod were subjected to a combination of stressors in a holding tank before being killed, pre rigor filleted and stored in ice. At slaughter, a higher level of stress was confirmed by blood physiology analyses. This was further associated with significantly reduced muscle pH and somewhat elevated muscle collagenase-like activity in the stressed fish, whereas no differences in cathepsin-like activities were found. After 5 days of iced storage, the stressed fish had significantly… CONTINUE READING
