The impact of temperature and salinity on the volume of the rotifer Brachionus plicatilis O.F.Muller under laboratory conditions.

We tried to rear rotifers of different size fractions, kept at controlled, sea water temperatures and salinities and fed with the unicelular algae Nannochloropsis sp., by combining three temperatures and three salinities in nine different ways. Observations on the growth and volume of the rotifers lasted ten days. Rotifers reared at 22 C and 20 psu averaged 758692 um3 (SD+-199504 um3), while those reared at 34 C and 35 psu averaged 425358 um3 (SD+-152530 um3). The ANOVA one way analysis of variance showed different results between groups of rotifers (P<0,05), thus, we can conclude that higher temperatures and salinities influence rotifersby decreasing body volume.
