The objective of this section is to provide useful information regarding different rotifer production methods and principles for managing rotifer systems.
General protocols and instructions for growing rotifers using the Instant Algae rotifer method will be discussed in the next section (E).
Best Production Methods
The variety of methods employed to grow rotifers is extensive, to say the least. Here are the basic choices that we see:
- High density vs. low density
- Continuous vs. batch culture (Equilibrium management vs. progressive density management)
- Monitor and feed by rotifer biomass vs. rotifer count
High density vs. low density
Aquaculture is always site and situation specific. There is no single right answer for every application. The same holds true for rotifers. In some tropical settlings rotifers are sometimes grown most cost-effectively in 100 metric ton tanks with densities of 100 to 200 per ml. In laboratory and intensive hatchery situations, where space and resources are expensive, rotifers are sometimes grown at densities exceeding 15,000 per ml. Most intensive hatcheries choose to grow rotifers at a density between 1,500 and 6,000 rotifers per ml.
