Seasonal sampling campaigns

X-IAS has begun its year-long monitoring of the Minho estuary, with the first field campaigns completed on 4-5 March and 3-4 June. The team sampled zooplankton, macroinvertebrates, fishes and the target invasive species: Corbicula fluminea, Egeria densa and Lepomis gibbosus, along with sediment and water. A first campaign to collect material for the stable-isotope analysis, which will place these species in the estuary's food web, has also been carried out.
