title: Experimental feeding rates of gelatinous predators Aurelia aurita and Mnemiopsis leidyi at low northern Baltic Sea salinity
abstract: The effect of the northern Baltic Sea's low salinity on feeding rates of a native scyphozoan Aurelia aurita and a recent invader to southern Baltic Sea, ctenophore Mnemiopsis was investigated experimentally. Incubations with Acartia spp. prey (4.19-25.16 indiv. l(-1)) were used to estimate clearance rates for both predators. Mnentiopsis leidyi digestion times were measured for several natural prey items. Wet weight (ww):length/diameter relationships as well as clearance rates (0.49 +/- 0.15 1 g(
