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

We tried to rear rotifers of different size fractions, kept at controlled, sea water temperatures and salinities and fed with the unicellular 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%oS averaged 758692um3 (SD-+199504um3), while those reared at 34 C and 35%oS averaged 425358um3 (SD -+152530um3). The ANOVA one way analysis of variance showed different results between the groups of rotifers (P<0.05), thus, we can conclude that higher temperatures and salinities influence rotifers by decreasing body volume.
