Abstract
An individual-based dynamic energy budget model is used in a Lagrangian
simulation to compute population dynamics for the rotifer strain
Brachionus plicatilis. This model structure allows description of
transient as well as stationary conditions, making the model useful for
a variety of applications. It also has the advantage of allowing the use
of dynamic energy budged (DEB) theory in describing rotifer energetics.
The model is developed with aquaculture-related applications in mind, including planning, monitoring and control of rotifer production systems
and first feeding of marine fish larvae. Simulations show acceptable
agreement with measured data on the population level, with regard to
steady-state egg ratio, yields of daily diluted cultures, and maximum
net growth rate. Further refinement of the model can enable its
application for processes such as essential nutrient enrichment of
rotifers for first feeding of larval fish.
