Description

The blue whiting is a slender cod relative of the family Gadidae reaching about 55 cm. The streamlined body is silvery with a blue-grey back and carries three separate dorsal fins and two anal fins; the lower jaw projects slightly and a chin barbel is absent. The species lives in open water above the continental slope of the north-eastern Atlantic and the Mediterranean, usually between one hundred and several hundred metres, forming huge schools that rise at night. It feeds on zooplankton, small crustaceans and small fish. The blue whiting is one of the most heavily fished fish in the world and is processed mainly into fishmeal and oil.
