The consequences of stress at slaughter on animal welfare and
post-mortem biochemical processes have been widely investigated
during recent years In many fish species, slaughter stress
was shown to greatly influence both welfare 4 and fillet quality during
storage, altering the freshness index (K) value,5 pH, color and
water-holding capacity.6,7 However, the influence of slaughter conditions
on oxidative stability of fillets during storage is still unclear.
The aim of the present study was to assess whether stunning/
killing of Atlantic salmon with CO affects fillet nutritional
quality or lipid peroxidation during storage compared with fish
