Discussion
- Males are assumed to differ from females by {p_Am} only
- In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3
- mod_1: males have equal state variables at b, compared to females
Facts
- egg development is initially fuelled by yolk only, later also absorb nutrients from fluids in the oviducts (Ref: Wass1973)
- Preferred temp 27 C,usually 20 - 65 m deep (Ref: fishbase)
