Fin's Fish Guide
The Blue ling (Molva dypterygia) is a saltwater fish of the family Lotidae that grows up to 155 cm.
Description
The blue ling is a very elongate cod relative of the family Lotidae reaching about 1.5 metres. The slender body is grey-brown with a bluish tinge and a paler belly; it has a long second dorsal and anal fin and a small chin barbel. The species resembles the common ling but is more slender, bluer and lives deeper. It occurs along continental slopes of the north-eastern Atlantic, usually between one hundred and fifty and one thousand metres. As a predator it hunts fish, crustaceans and squid. The blue ling spawns in deep areas, sometimes in dense concentrations that are vulnerable to fishing. Its firm white flesh makes it a valued commercial deep-sea fish.
