  • Small yolk sack at hatching, but length at birth is not given
  • In plankton during early juvenile stage, later bentic, but age is not given This event is indicated by metamorphosis, but no acceleration is assumed
  • The supply stress s_s = 1.7e-5, rather than around 3e-3, which is more typical for a rayfinned-fish. Larger weight for s_s affects MRE, however.
  • In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3
