Roach. A small freshwater fish similar to carp. It has many bones, which discourage most people from eating them.
Whitefish, pollan or vendace. A small relation of char or lake whitefish and is a slightly oily freshwater fish of northern Europe, prepared in the same way as trout. It can be baked or fried.
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. Varieties are found all over the world. The roe is used for taramasalata, botargo, boutargue.
