Food incorporation of vulnerable marine ecosystem (VME) indicator taxa from the Azores, Viminella flagellum and Dentomuricea meteor under competition

DOI

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.
