posterAbstract
The mesozooplankton (200 μm to 2 mm) community from monthly samples collected at two stations
in Ría de Vigo (39 m) and its adjacent shelf (97 m) between 1995-2003 is described. The
mesozooplankton was dominated by copepods. Inside the Ría, meroplankton (larvae of gasteropods,
lamelibranchiae, echinodermate and cirripids nauplii) and other holoplanktonic organisms, such as
apendicularia, cladocera, siphonophora and medusae, were also well represented. The copepod
group inside the Ría was dominated by Acartia clausi, juveniles of Calanus helgolandicus, Paracalanus
parvus, Pseudocalanus elongatus, Temora longicornis, Oithona plumifera, Oncaea media, Euterpina
acutifrons and copepodites of Centropages spp. In the offshore station, dominant copepods species
were the same than inshore together with other oceanic species, such as Paraeuchaeta hebes,
Calanoides carinatus and Aetideus armatus. Biomass values within Ría de Vigo ranged between
2 and 151 mg dry weight /m3 and between 2 ...
