The Effects Of Varying NaCl Concentrations On The Cultures Of The Rotifer, Brachionus plicatilis

Abstract

Populations of the rotifer, Brachionus, plicatilis. were cultured in medium containing various concentrations (2, 5, 10, and 20 gl-1) of NaCl. Comparisons of the life history characteristics show that the media containing 2, 5, and 10 gl-1 of NaCl sustain positive population growth; the media containing 10 gl-1 of NaCl has the highest levels of survivorship and reproduction. The medium containing 2 gl-1 of NaCl is inadequate for sustaining a population of Brachionus plicatilis indefinitely.
