  • The larval stage lasts 202 days and no feeding occurs (ref: Wiki)


  • I found information on the number of eggs per female as a function of length in Anon2013 that was much higher than in Anon2015 but chose to not include it as the temperature was not provided
  • I was surprised to observe that the weights coefficient for ab changed so much the parameter values
  • 24 hrs may not be enough for all food to assimilate and digest; so may want to provide lower weight for this
