Discussion
- Males are assumed to differ from females by {p_Am} and h_a only
- Reproductive output is assumed to correspond to am = 1 yr, the most frequent max age
- mod_2: males have equal state variables as females at b
Facts
- Spawning over 4-6 months, several capsules per clutch, at least 2 clutches (Ref: MaxwHanl2000)
- typically lives for 1 yr, some reach 2 yr, and occasionally 3 yr (Ref: Summ1971)
- sex dimorphy, sex ratio 1:1; brood in july & nov (Ref: Summ1971)
- Programmed death, not by ageing (Ref: Wiki)
