Rock-Fish

rock-fish a collective name indicating any of various fish which frequent rocky bottoms in the sea. Some fish which live among rocks are large (e.g. the groupers and the conger eel), but the collective term usually refers to the small species which are useful for going into fish soups etc. and which need not be precisely identified. The French term poissons de roche has the same meaning and is a label often seen on a pile of miscellaneous small fish for sale.
