Discussion

  • z is not well-fixed by data, size ultimate size is much larger than size at death
  • in view of fitting results, puberty does not coincide with mating and part of structure converts to eggs just before death
  • model abj has been used, meaning that settlement has no effect on acceleration

Facts

  • semelparous: death at first spawning, female ventilates eggs and dies after hatching; No food intake during this period (Ref: ZuniOlvi2014)
  • small eggs with a planktontic larval stage (Ref: ZuniOlvi2014)
  • males and females grow at the same rate; males mature before females (Ref: CortGonz1999)
