Viminella flagellum and Dentomuricea meteor specimens were collected from scientific longline fishing in the Condor Seamount (38˚08′N, 29˚05′W). Food incorporation of two co-occurring species Viminella flagellum and Dentomuricea meteor was measured under laboratory conditions by tissue incorporation of stable isotopes 13C and 15N. Specimens were kept in 35 l flow-through aquaria. Experiments lasted for 6 days, with feeding incubations lasting for 12 hours, while the feeding episodes happened, the flow-through system was closed creating a recirculating system where water currents were created by a rotating engine. Food incorporation was measured under two different flow speeds (2 and 4 cm/s) and under two different conditions: competition (the two species together) and control conditions (each species tested individually).
4 cm/s: Both species present in the aquaria, flow speed 4 cm/s2 cm/s: Both species present in the aquaria at, flow speed 2 cm/sC 4 cm/s: Viminella flagellum alone, flow speed 4 cm/sC 4 cm/s: Dentomuricea meteor alone, flow speed 4 cm/sC 2 cm/s: Viminella flagellum alone, flow speed 2 cm/sC 2 cm/s: Dentomuricea meteor alone, flow speed 2 cm/sMeasurements taken in "open system" refer to the measurements taken prior to shutting down the flow-through systems to create the experiemtal conditions. Measurement taken under "closed system" correspond to measurements taken when the incubation time was over.
