Facts

  • This species is hermaphroditic (ref: Wiki)
  • Egg cannibalism by hatchlings is frequent (ref: cabi)

Discussion

  • Kappa_R = 0.95/2 because of hermaphroditism
  • Selection for growth is assumed to affect digestion efficiency kappa_X and spec max assim {p_Am} only, letting {p_Xm} unaffected
