Discussion
- 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.
Facts
- 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% of the maximum (Ref: Pear1965)
- GSI cycle is not significantly different between males and females (Ref: Pear1965)
- This entry is discussed in AgueColl2016 (Ref: AgueColl2016)
