Abstract
Skin color of ocean perch (Sebastes marinus), measured instrumentally, was at least as good when the fish were held up to 12 days in refrigerated sea water (RSW) at −1 C as when they were held in ice. Adding carbon dioxide to the RSW generally enhanced skin color retention. The loss in total extractable carotenoid pigments was not much affected by the storage conditions. The fish stored in RSW with CO2 were kept in better condition, as measured by trimethylamine production in the fillet tissue, than in ice or RSW. The ionic diffusion, sodium uptake, and potassium loss between the fish and the RSW did not appear excessive but did not reach equilibrium in 12 days storage.Keywords
