Post-mortem changes in skin colour

Post mortem changes in skin chromaticity parameters were observed in all treatments. In carotenoid fed fish there was a significant decrease in brightness (L) and in ECI from Day 3 to day 7 of storage on ice. This decrease is also observed in wild fish stored under similar conditions. The use of skin colour as an index of freshness was verified by correlation with established freshness indexes.
