Facts

  • most ubiquitous Arctic fish, found in diverse arctic and subarctic habitats ranging from brackish to fully marine waters, from coastal to offshore waters and from surface waters to great depths (ref: BoucMoll2016)
  • Adults tend to avoid high temperatures (ref: GrahHop1995)
  • lose about 50
  • larvae prey on: C. hyperboreus and C. glacialis (ref: BoucMoll2016)
  • feeds on amphipods, copepods, adults from the Arctic domain feed mostly on Themisto libellula (large Arctic amphipod) (ref: HopGjos2013, NahrVarp2014)
  • has the largest and fewest eggs of all Gadidaes. Distribution associated with ice; especially characteristic of regisions between pack ice and drift ice. Main consumer of plankton in the Arctic seas. (ref: Andr1954)

Discussion

  • KunzFric2016: energy content of food 20.4 kJ/g dry weight (pers comm company making the food)
  • We included only laboratory data and field data from individuals taken around svalbard.
  • Some gonadal mass may be retained after spawning (not taken into consideration here).
