  • Oogenesis takes 18-24 months to complete (ref: Pear1965)
  • Spawning occurs annually between May - August (winter) (ref: Pear1965)
  • After spawning, remaining GSI is aprox. 20
  • GSI cycle is not significantly different between males and females (ref: Pear1965)
  • This entry is discussed in AgueColl2016 (ref: AgueColl2016)


  • maximum GSI as reproduction buffer accumulated during 1.2 years, due to the fact 1-3
  • T-JO: animals were starved for 4 weeks prior to the start of the temperature ramp, and were not fed during the experiment (3 more weeks). I think that even for these slow animals we can consider that assimilation is not happening.
