Pacific cod
The sablefish is a species of deep-sea fish common to the North Pacific Ocean. Adult sablefish are opportunistic feeders, preying on fish, including Alaskan pollock, eulachon, capelin, herring, sandlance, and Pacific cod, as well as squid, euphausiids, and jellyfish. Sablefish are long-lived, with a maximum recorded age of 94 years although the majority of the commercial catch in many areas is less than 20 years old.
