Grey mullet, the commonest and largest of the grey mullet (US: striped mullet) family. It is a silver, shoal-living fish pointed with dark grey which feeds on seaweed and plankton near the muddy bottom in estuaries and coastal waters. This can effect its flavour. However, a good grey mullet, caught in clean water, is round-bodied and has creamy white flesh and good flavour with good keeping capabilities. It must be thoroughly scaled before eating.They are used for sashimi only when extremely fresh. The roe of the female is made into karasumi, a Japanese version of botargo.
