Management and handling hazards
The elimination of a separate enrichment handling had a positive
impact on the physical quality of the rotifers. During the enrichment
cycle rotifers are exposed to concentrated formulations reducing the
rotifers' vital functions and requiring extra oxygen supplementation.
This deadly combination, together with the passage through the
concentrator/rinser is one of the most critical handlings as it determines
to a large extent the physical quality of the rotifers . Rotifers exposedtoa
second handling for enrichment displayed more injuries (Fig. 4,right),were more exposed to rafting (Fig. 4, middle) resulting in a loss of 10–20% of the population (Fig. 4, left). Damaged rotifers are also prone to microbial, fungal or viral infections compromising their life and/or
that of their predators
