Rotifer : Zooplanktonic animal that serves as food (live prey) for fish larvae.

The meiofauna collection of the Muséum national d’Histoire naturelle includes various groups, such as rotifers, tardigrades and many worms.

The effects of ethylene glycol on reproduction in the rotifer, Brachionus calcifloris, were recently assessed by Beak Consultants Ltd.

Provided is a method for producing young prawns, the method comprising providing prawn larvae with Chlorella, a rotifer and Artemia as a biological feed.

At this stage, larva only accept small zooplankton (rotifer and brine shrimp) which has to be farmed aside in the hatchery and frequently distributed.

Before this, the rotifer – another microscopic water creature – was believed to have the most foreign genes of any animal, with 8 or 9 percent.

Aqua-Crobes also improves artemia, copepods and brachionus survival by improving water quality for culture.

A process is claimed for decapsulating crustacean or rotifer eggs wherein the outer shells of the eggs are removed by dissolving the outer shells of the eggs by means of a liquid medium containing permanganate.

ISO 20666:2008 specifies a method for the determination of the chronic toxicity to rotifer Brachionus calyciflorus, based on population growth inhibition in 48 h.

He argued that a vorticella with an eye having only a cornea must receive different representations of objects than a spider, which has a more complex eye with lenses.

Precisely how the rotifer Brachionus leydigii arrived in the Great Lakes is not known, but contaminated ballast water discharged by oceangoing ships sailing up the St. Lawrence Seaway is a likely answer.

Yes, you do have the task to seek them out drop by drop, but Edmondson notes that it is the only method which makes it possible to fix some specimen of Notommata (a very difficult to fix rotifer) with its "auricles" spread out well.
