Wreckfish (Polyprion americanus)

A member of the Polyprionidae family and related to the giant sea bass, the wreckfish is a very deep-dwelling and large-growing species occasionally caught by heavy-tackle anglers probing extreme depths.

It is marketed fresh or frozen, sometimes as a sea bass or a stone bass, although it is susceptible to overfishing and is regulated in U.S. federal waters.

The second dorsal, as well as the caudal and the anal fins, are often edged in black, although the rounded caudalfin is otherwise edged in white, as are the pectoral fins. The spinous and soft parts of the dorsal fins are notched, and the lower jaw projects past the upper jaw.


The wreckfish grows slowly but can eventually reach 7 feet or more in length and can weigh 100 or more pounds. The all-tackle world record is a 106-pound, 14-ounce fish taken off Portugal.


Wreckfish feed on crustaceans, mollusks, and deep-dwelling fish found around wrecks or underwater objects.


In the western Atlantic, the wreckfish ranges from Newfoundland to North Carolina.


Found in the deep part of the continental shelf, at up to 2,000-foot depths, wreckfish prefer rocky ledges, pinnacles, and outcroppings around ship-wrecks. They are solitary fish and are sometimes found drifting with floating timber or other objects.
