Continuous vs. Batch
(equilibrium feed chemostat vs. progressively increasing density and feeding)
Continuous and batch rotifer system are simply two methods of managing the same rotifer population dynamic. In continuous systems you harvest 25% to 45% of the culture every day and “reinoculate” with the remaining 5575% of your culture volume. In batch system you harvest every 35 days and reinoculate with 1030% of your culture volume. While rotifer growth dynamics may be the same, there are significant differences in how you manage continuous and batch systems.
Population Dynamics – Continuous and Batch systems
In theory, rotifer population dynamics of continuous system and batch system are the same.
Continuous:
Batch Culture:
