Non-indigenous bivalves (Mollusca) from the Cantabrian Sea (Bay of Biscay)

Abstract

Event Abstract Back to Event Non-indigenous bivalves (Mollusca) from the Cantabrian Sea (Bay of Biscay) Irene Fernández Rodríguez1*, Andrés Arias Rodríguez1 and Nuria Anadón Álvarez1 1 University of Oviedo, Department of Organisms and Systems Biology, Spain Alien or non-indigenous species represent a potential risk to receiving ecosystems, since they may develop an invasive behavior, negatively affecting the native diversity and causing, in some cases, economic losses. On the case of introductions of marine species, the most frequent vectors of introduction are the shipping (e.g. ballast water, biofouling) and the aquaculture activities. Furthermore, Global Warming may play a role in the establishment of alien species in new areas. The Cantabrian Sea (southern Bay of Biscay) is considered a potential area for the successful establishment of alien species. It is an area influenced by the Gulf Stream with a gradient of warmer water, and delimited northwards and westwards by regions with colder waters. On the other hand, during the last decades, there has been an increasing on the average water temperature in associated to global warming (IPCC, 2007). Here we present an updated review of the alien bivalve species reported in the Bay of Biscay until the date. A total of 15 species from 9 families of class Bivalvia (Pharidae, Veneridae, Ostreidae, Mytilidae, Arcidae, Semelidae, Pectinidae, Chamidae and Kelliidae) were reported as introduced, and four of them - Ensis directus, Ruditapes phillippinarum, Crassostrea gigas and Xenostrobus securis -have showed an invasive behavior: (Arias & Anadón 2012; Pejovic et al. 2016). The manila clam, R. phillippinaru and the Pacific oyster C. gigas were introduced by means of aquaculture and the American razor clam, E. directus, and the New Zealand pigmy mussel, X, securis,by ballast water. More recently, several specimens of Anadara transversa and Ostrea stentina have been reported for the fisrt time in the Bay of Biscay, from the Villaviciosa and Eo estuaries and the Avilés Port respectively (Fernández-Rodríguez et al. 2016; Pejovic et al. 2016). Although a harmful behavior has not been reported for those species yet, they certainly have the potential to become invasive and thus monitoring studies should be undertaken in order to ascertain its evolution in the area.
