Facts

  • At 7C hatching occurred at 256 hpf = 10.7 dafter which individuals remained motionless at the water’s surface undergoing negative phototaxis only after the first day posthatch.First-feeding stage was reached at the end of the third day posthatch, subsequent to development of a functional jaw and hindgut (ref: HallSmit2004)

Discussion

  • Weight for Wwh is set on 0 because of inconsistency with other (embryo) data
  • Parameter s_R is introduced to account for the fraction of absorbed eggs, assuming that fecundity (Ri and LN data) is based on counts in gonads
  • The overall fit is not high, probably because the various data sets relate to different populations with different parameters; the embryo data suggests that the egg is larger than presently predicted and some scaled functional responses seem surprisingly high.
