k 0.3 0.01955 - maintenance ratio

kap_G 0.8 0.8035 - growth efficiency
kap_R 0.95 0.475 - reproduction efficiency
s_s 0.01 0.0001619 - supply stress

Discussion

  • Reproduction efficiency kap_R has been set to 0.95/2 because the species is simultaneous hermaphroditic

Facts

  • The female deposits her eggs and dies shortly thereafter, while the male remains in the tube to "incubate" the eggs (Ref: MoorDill1993)
  • Larval development is direct via a non-planktonic metatrochophore larvae and occurs entirely within the parental tube; juveniles exit the tube 3 to 4 wk after egg deposition (Ref: MoorDill1993)
