“…This species is a small brown mussel endemic to the brackish waters of New Zealand and Australia (http://www.ciesm.org). It has also been reported to be an invading species in Italian coastal lagoons (Lazzari and Rinaldi 1994;Sabelli and Speranza 1994), the Po River delta (Russo 2001), French Mediterranean lagoons and in Japanese waters (Kimura et al 1999;Kohama et al 2001). The historical introduction of various alien molluscan species in Galician waters is known to many malacologists, especially in estuaries supporting highly productive shellfish farming (Rolá n et al 1985).…”

The presence of the non-indigenous species, the black-pygmy mussel Xenostrobus securis, is reported here for the first time in an intense shellfish farming area off Galicia (NW Spain). Very high concentrations of this mytilid bivalve have colonized estuarine waters located at the inner part of the Ria de Vigo. The invasive role of X. securis is discussed in the context of the wide ecological tolerance of the species and the recent finding of settlements of this species on numerous colonies of the economically-important blue mussel Mytilus galloprovincialis. The mode of introduction of the black-pygmy mussel is also discussed in relation to human management activities.

The mussel Xenostrobus securis: a well-established alien invader in the Ria de Vigo (Spain, NE Atlantic)

Biological and habitat characterization of the non-indigenous invasive species Xenostrobus securis was undertaken in the Ria de Vigo. This study included genetic identification of mussel samples collected from introduced and endemic areas, and the assessment of mussel size, population abundance, geographic distribution, pathological condition, and sediment composition of substrata type. The mussel had a marked patchy distribution, being more abundant in brackish sites with fine sediments and high organic matter content. Pathological analysis revealed that X. securis does not play any role as vector for introducing allochthonous pathogens in the Ria de Vigo. Nevertheless, depending on its invasiveness potential, the mussel could be a key host favouring spreading and epizootic outbreaks of marteliosis which is known to be harmful for local bivalve populations. Phylogenetic analyses of the COI gene placed all the resulting sequences in a clade within the genus Xenostrobus and its phylogeny congruent with an Australian/Pacific origin. The COI tree suggests two historical introductions in European waters. One of these invasions seems to have started in Galicia, moving from there towards Italy and France, while the geographical spread of the second invasion cannot be deciphered, although the Australian/Pacific origin of this invasion seems very possible. The 18S network is congruent with one invasion starting in Galicia or in Italy, as the Australian haplotype is closely related to the haplotype found in these areas. Several hypotheses accounting for the colonization history of this species in Galician waters are discussed.

“…7(b)). X. securis, with a longevity of 1-2 years similar to H. dianthus (Grave 1933, Kohama et al 2001, also may have gained advantage in their competition over the latter, with only one recruit time in summer (Dean & Hurd 1980) by having two yearly recruit times in summer and autumn (Kohama et al 2001). Chitons and limpets that prey on juvenile H. dianthus together with small macroalgae on the substrata are not a limiting factor for the distribution of H. dianthus at Maishima because they did not occur here at all ( Table 2).…”

During our survey of the subtidal macrobiota on wave dissipating concrete blocks along the coast of Osaka Bay in 1997, we recorded a species of serpulid polychaete that was not immediately identifiable. In 2007, we reexamined the specimens and discovered that they were identical to Hydroides dianthus, native to the East Coast of North America. The density of the worm in Osaka Bay varied remarkably between sites and depths. A Steel-Dwass multiple comparison analysis was used to evaluate the differences among sites, depths and seasons. Spearman's rank correlation was used to examine the influence of physical factors of temperature, salinity and dissolved oxygen, and biological ones of the densities of coexisting organisms. The results suggest that salinity greater than 30 psu and biological interaction with macroalgae or mussel (Xenostrobus securis) are presently acting as limiting factors for the invasion of H. dianthus.
