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
- males are assumed to differ from females by {p_Am} only
- mod_1: males have equal state variables at b, compared to females
Facts
- semelparous: death at first spawning, female ventilates eggs and dies after hatching; No food intake during this period (Ref: Fors1984)
- large bentic eggs (Ref: Fors1984)
