With increasing size and habitat depth, the diet diversifies and includes more scavenging of squid, fish, and crustaceans.
In the legal toothfish fisheries managed by CCAMLR and countries with territorial waters, the most common method is fishing by longlines where a long “mainline” is set in the water, with many baited hooks coming off that line.
Toothfish are caught by longline, trawl and pot, typically in depths of m.

Launch the Aquatic Species Distribution map viewer. Trawling generally catches toothfish in the smaller size range, which requires calculations to be made at the annual stock assessment meetings of CCAMLR to take these catches of smaller-sized fish into account, and lowers the overall available catch of toothfish by trawl.
In addition, toothfish must be caught from vessels equipped with satellite-linked automated VMSs that track vessel movements from port-to-port to ensure compliance with set quotas and boundaries.
