Discussion

  • Growth in volume ceases some 1.5 d at transition from naupliar to copepodite stages and permanently at puberty; the fist hold is here ignored and is also not visible in t-WN data
  • The temperature for tV data had to be guessed
  • Males are assumed not to differ from females
  • tJN data was ignorned because out of range; it is hard to believe that a 1.4 mug N animal excreates 0.55 mug N/d.

Facts

  • 6 nauplier stages, and 6 copepodite stage; nauplier stages 1-2 do not feed (Ref: Wiki)
