Abstract

AbstractThe goal of our study was to examine the effects of low abundances of nylon fibers on feeding rates of calanoid copepods (Crustacea, Copepoda) and doliolids (Tunicata, Thaliacea) in the presence of diatoms at near environmental concentration levels. In addition, we examined microscopically the fecal pellets produced by copepods and doliolids in the presence of fibers. Adult females of the calanoid Eucalanus pileatus and early gonozooids of Dolioletta gegenbauri (both of similar dry weight) cleared the diatom Rhizosolenia alata at similar rates. Nylon fibers were cleared at higher rates by Dolioletta gegenbauri compared to Eucalanus pileatus. Examination of fecal pellets revealed that copepods and doliolids could ingest the about 300 µm long fibers. The latter also ingested the occasionally occurring fibers of > 1 mm length. It appears that in seawater fiber abundances of about seven fibers ml−1 did not have a negative effect on feeding of either E. pileatus or D. gegenbauri. As doliolids and copepods remove plastic fibers from seawater by packing them into their pellets, they might play a role in the reduction of microplastic pollution and the microplastic transfer from the water column to the seafloor. Calanoid copepods may limit ingesting fibers by not perceiving them, as compared to doliolids which do not seem to be able to avoid ingesting them.
