  Gemfish have blue backs and silvery flanks and undersides. They can grow to a maximum length of 135 cm, but average from 60-90 cm.
 
 
  Gemfish have a maximum age of 17 years. There is little information about age at maturity. Spawning is thought to occur in July around North Cape and August-September in the north of the South Island.
 
 
  Gemfish are found throughout New Zealand on the continental shelf and slope. They are usually found at depths of 50-600 m. Gemfish feed on squid, lanternfish, dories, and rattails.
