The cod-like cusk, Brosome brosome, is a member of the family Lotidae.
Found on both sides of the North Atlantic in deep cold waters, these fish feed on various smaller fish, crustaceans, and other soft-bodied invertebrates, including starfish. They are slow-growing and may reach four feet long with a weight of over thirty pounds after 14 years.
Cusks have firm white flesh that holds together well, making them a favourite for chowders and soups. Although not directly targeted, they are often caught in trawls that are after more valued cod, haddock, and pollock.
A heavy Norwegian metal jig fooled the specimen pictured, and it was hand-cranked from a depth of 340 feet.
