Mytella strigata (Hanley, 1843) emerging as an invasive marine threat in Southeast Asia.
The Central and South American mytilid mussel Mytella strigata was recently reported from the Philippines and Singapore, where its population has expanded exponentially in the last two years. We report the species has recently become widespread in the inner Gulf of Thailand, with densities reaching 40,800 m-2. It is a potential threat to lucrative Asian green mussel (Perna viridis) aquaculture and could be introduced to Australia, where it could foul pearl aquaculture farms. The concurrent finding of the invasive false mussel Mytilopsis sallei at two new sites in Thailand emphasises the urgent requirement for a detailed invasive marine species survey in the region.
