Rudderfish (Centrolophus niger) is a saltwater species recorded in the United States. It is found at depths of 40–1050 m.
Scientific name: Centrolophus niger · Water: Saltwater
Size: up to 150 cm
The rudderfish is an oceanic centrolophid, epipelagic or mesopelagic, found from 40 to 1,050 m; juveniles live in surface waters associated with pelagic medusas and salps, while adults are found deeper. It may form small schools and appears to feed on whatever is available: small fish, squid, large pelagic crustaceans and other plankton. Maximum length is about 150 cm standard length, commonly about 60 cm total length. It is of potential interest to fisheries and is a gamefish, with a very high price category. Fishing vulnerability is very high at 85 of 100 and resilience very low, and climate vulnerability is moderate at 38 of 100. IUCN lists it as least concern.
