When checked at the beginning
and end of the trial period the rotifers showed good, active swimming behaviour.
After enrichment the rotifers were well fed (full stomachs)
NOTE:The initial condition of the rotifers is important regarding potential
gains/losses in the rotifer population during enrichment. (Source:
