  • No evidence of spawning or reprod-cycle synchronisation. Larger females do not produce larger eggs. Females are much more abundant (99:1), might be a result of catching method. Initially both male and female gonad develop, then one of them reduces. Hermaphrodites are rare (0.2-0.3 percent). Male and female mature at same size. Reduction in L_p, W_p with reduction in average ind in the pop (DEB interpretation is: k_J < k_M) (ref: GranBish2009)
  • "On the southwest slope of the Grand Bank, Atlantic hagfish are not captured in shallow sub-zero waters and appear to concentrate (greatest catches) within the warmest (5.8-9.0C) available bottom waters which occur within depths of 125-400 m." (ref: GranBish2009a)
  • "There is no known method of aging hagfish however a recent review of conceptual models of hagfish fishery science and management suggested growth may approximate 20 mm/year" (ref: MartGran2007)


  • ASSUMPTION: reproduction is once per year
  • The only measured rate in the data below is the respiration rate
  • blood volume = 18
