The Patagonian Toothfish is a large fish found on seamounts and continental shelves around most sub-Antarctic islands and temperate waters of the Southern Atlantic, Southern Pacific, Indian, and Southern oceans. The Chileans were the first to market toothfish commercially in the United States, earning it the name Chilean sea bass, although it is really not a bass and it is caught in many other waters outside Chile. This large deepwater fish is found between the depths of 1600 - 3200 feet. The average weight of a commercially caught toothfish is 20 pounds with large adults occasionally exceeding 440 pounds. Big, moist tender flakes of flavor are the trademarks of Chilean Sea Bass. Meat from the raw Chilean Sea Bass is snow white. When cooked, the meat remains white, comparable to cod in appearance. Chilean Sea Bass is fished by long-line boats and is usually headed gutted and frozen on the boat at sea. They feed largely on squid, small fish and prawns. All of our suppliers adhere to all toothfish importation rules and regulations as prescribed in the Federal Register Vol. 68, No. 84 / Thursday, May 1, 2003 (50 CFR Part 300).
