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

Facts

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