This is a collaborative project funded by the Marine Institute, Galway and co-ordinated by GMIT (2020-2021). The research is investigating microplastic loading and retention times in the Dublin Bay prawn Nephrops norvegicus around the Irish coast. The project will also investigate microplastic concentration within the sediment habitat. The Dublin Bay prawn is an extremely valuable fishery resource within EU waters. Due to its high economic value and ecological relevance, this crustacean has the potential to act as a flagship species for plastic pollution in the deep-sea.
