The Chilean Sea Bass Fish (toothfish) is a deep-sea fish also known by the less attractive name “toothfish” and is caught in ocean waters around Antarctica. Most of the Chilean seabass is managed responsibly, but there are still some areas where it is overfished. If you are not sure, ask the seller if they know if the fish was caught legally or not. Demand and the resulting overfishing mean that Chilean seabass tends to be relatively expensive, but its mild flavor and delicious texture make it well worth the price.

Chilean sea bass is white fish rich in omega-3 fatty acids with a unique texture in large flakes and a mild flavor. The healthy fat makes the fish a little easier to cook because it won’t get tough like other fillets if it’s a little overcooked.

One valuable characteristic is that the flesh contains a high level of Omega-3 fatty acids that are released when cooked. Omega-3 fatty acids have become recognised for their health benefits.
