Also, large predacious ciliates (haptorians) can reduce the abundance of small metazoans, such as rotifers
(Noges et al.

Hexarthra fennica and Brachionus plicatilis (Vignatti, 2011; Vignatti et al.
Enhancement of rotifer
(Brachionus plicatilis) growth by using terrestrial lactic acid bacteria.
In addition, the nutritional quality of the copepods, including the fatty acids content, was compared with rotifers
crassipes showed higher values of frequency of occurrence of rotifers
and algae in the first (6 to 12 days), second (15 to 21 days) and fourth (33 to 39 days) age classes and Chironomidae, in the third age class (24 to 30 days).
and Harpacticoida copepods, as well as nauplii and copepodites of Cyclopoida and Calanoida, were not identified to lower taxonomic level.
It is summarized that density of Rotifers
remain highest during summer, when plenty of food is available where as diversity of Rotifers
reaches to its maximum when riverine water, carries variety of Rotifers
, mixes with the stagnant and isolated flood plain water.
The exclusion of rotifers
and copepod larval stages is undoubtedly one of the reasons why in our results there was a strong dominance of cladocerans at the three studied environments.
, copepods, cladocerans, and meroplankton dominate in the northeastern Gulf of Riga (Kotta et al.
The major groups of zooplankton encountered were copepods rotifers
in aging research: use of rotifer
to test various theories of aging.
The density of Rotifers
increased rapidly when the imazethapyr and imazapic herbicide was applied, but decreased later (3DAA), after which there was an increase where the density remained high until 22DAA.
