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 bothwelfare4 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
