Flesh – buying fresh
The flesh of fish should be firm to the touch and shiny in appearance.
The flesh of white fish should be translucent and should be free of any defects such as bruises, blood clots or parasites.
There should be no sign of 'gaping' - meaning the flesh should be firm and compact and not exhibit any signs of ragged gaps.
When buying fillets look out for neatly trimmed fillets and a white translucent appearance.
