Discussion

  • Chemical pars are assumped to relate to ash-free dry mass; MaleFaga1993 report ash free dry mass over dry mass ratio of 0.263 - 0.297 with mean 0.279, which makes del_W = 3.5842
  • mod_3: guessed data added to allow parameter estimation; kappa fixed at 0.95 in absence of reproduction data

Facts

  • C. antarctica feeds mainly on copepods (Ref: SeJoScol2004)
  • Is found is Magellan Strait and the Antarctic Ocean; C. antarctica egested little else than clear pieces of disarticulated exoskeleton (Ref: ScolDaly2006)
  • The similarity in feeding incidence between autumn and winter, despite a large seasonal variability in prey abundance, suggests that other factors, such as prey patchiness, may significantly influence feeding (Ref: ScolDaly2006)
  • Hermaphrodite (Ref: Wiki)
