Two vessels of a domestic shipping line appear to have served as a transport vector for the Asian green mussel Perna viridis (Linnaeus, 1758) between regions. This species is indigenous in the western but not in the eastern part of the archipelago, separated historically by the Sunda Shelf. The green mussels collected from the hulls of the ferries when in eastern Indonesia showed a significantly lower body condition index than similar-sized individuals from three different western-Indonesian mussel populations. This was presumably due to reduced food supply during the ships' voyages. Although this transportinduced food shortage may initially limit the invasive potential (through reduced reproductive rates) of the translocated individuals, the risk that the species will extend its distributional range further into eastern Indonesia is high. If the species becomes widely established in eastern Indonesia, there will then be an increased risk of incursions to Australia, where the mussel is listed as a high-priority pest species.Mussels were collected between 0.5 m and 2 m depths at all stations.Supplement to: Huhn, Mareike; Zamani, Neviaty P; Lenz, Mark (2015): A ferry line facilitates dispersal: Asian green mussels Perna viridis (Linnaeus, 1758) detected in eastern Indonesia. 4(1), 23-29105.76666129.883333-6.98333-3.63333
