Discussion

  • Males are assumed to differ from females by {p_Am} and E_Hp only
  • This entry suggests that the incubation time exceeds a yr, which might be the reason with females skip a year between pregnancies
  • mod_1: males have equal state variables at b, compared to females

Facts

  • Ovoviparity (aplacental viviparity) (Ref: fishbase)
  • Preferred temp 21.9 - 28 C, usually 0 - 90 m deep (Ref: fishbase)
  • Ww (in g) = 0.00490*(TL in cm)^3.11 (Ref: fishbase)
