Laboratory culture of marine planktonic oligotrichs (Ciliophora, Oligotrichida)

Abstract: Marine planktonic oligotrichs of the genera Strombidium and Strombidinopsis were collected from the Northwest Arm of Halifax Harbour, isolated, and maintained in monospecific batch culture for periods ranging from weeks to 10 mo. Successful laboratory culture was a function of appropriate phytoplankton food and the chemical composition of the oligotrich culture medium. Maximal reproductive rates, as doublings per day, were obtained when the oligotrichs were fed 2 dinoflagellate strains, Heterocapsa triquetra a… Show more

“…Importantly, different ciliate species did not respond uniformly to pre-screening. A negative effect of prescreening on fragile ciliates due to mechanical shear forces has been reported previously (Gifford, 1985) and could be shown here for Strombidium cf. tressum and more moderately for the strobilid Lohmanniella oviformis.…”

“…tressum (51% loss) was very strong taking into account that the mesh size was 200 mm and therefore at least five times the size of the biggest individuals of this species. Compared to the loss rates of oligotrichs due to 202 mm screening (23 -37%) published by Gifford (1985) our results for the pool of the most abundant ciliates are almost in the same size-range (17%). In contrast to the ciliates, no effect of the pre-screening process was detectable on dinoflagellates.…”
