Sablefish

[sey-buhl-fish]

The sablefish, Anoplopoma fimbria, is one of two members of the fish family Anoplopomatidae and the only species in the Anoplopoma genus. In English it is also called sable (USA), butterfish (USA/Australia), black cod (UK, Canada), blue cod (UK), bluefish (UK), candlefish (UK), coal cod (UK), and coalfish (Canada), although many of these names also refer to other species.

The sable fish is found in muddy sea beds in the North Pacific at depths of 300 to 2,700 meters, and is commercially important to Japan. It also is considered a delicacy in many countries for its sweet taste and flaky texture.

Ecology

The sablefish (Anoplopoma fimbria) is a species of deep sea fish common to the North Pacific ocean. Adult sablefish are opportunistic feeders, preying on fish (including walleye pollock, eulachon, capelin, herring, sandlance, and Pacific cod), squid, euphasids, jellyfish (Yang and Nelson 2000). Sablefish are long-lived species, with a maximum recorded age of 94 years (Kimura et al. 1998).

Nutrition

Sablefish is very high in healthy long-chain omega 3 fatty acids, EPA and DHA. It contains approximately as much as wild Salmon, in addition Sablefish are also very low in PCBs, dioxins, and mercury.

Confusion

"Snow Fish" is short of supply in Thailand due to its popularity, and many Japanese restaurants in Thailand use Patagonian toothfish (Dissostichus eleginoides), also known as Chilean Sea Bass, as a substitute.
