“…Competition has been suggested as the reason for finding lower abundances of the caprellids, C. equilibra and C. dilatata (both common members of Mediterranean fish farm fouling; Fernandez-Gonzalez, unpublished data) in harbours where C. scaura was present (Guerra-García et al 2011;Ros et al 2013). These abundance patterns have been found also during the present study.…”

“…bryozoans, algae, seagrasses and mussels) and are related to shoreline areas, mainly marinas (Krapp et al 2006;Guerra-García et al 2011) and coastal lagoons (Mizzan 1999;Souissi et al 2010;Prato et al 2013), which are often highly susceptible to alien species (Occhipinti-Ambrogi et al 2011). These areas generally experience high shipping activity; thus, the vector of introduction into the Mediterranean Sea is suspected to be hull fouling (Krapp et al 2006), and the role of recreational boating in the secondary dispersal has also been discussed (Martínez and Adarraga 2008;GuerraGarcía et al 2011 and references therein).…”

“…In addition, aquaculture industry, and in particular the movement of fish cages, was also suggested as vector for introductions (Krapp et al 2006;Martínez and Adarraga 2008). Little is known about the relation between C. scaura and aquaculture, except from reports on land-based aquaculture tanks on the Canary Islands (Guerra-García et al 2011), and on fish farm cages in a semi-enclosed bay off the Turkey coast (Bakir and Katagan 2011), when fish farms were still located close to the coastal zone at shallow, sheltered sites. Notwithstanding this, no mention has been made for fish cages located in off-coast conditions.…”

The non-indigenous caprellid Caprella scaura Templeton, 1836, native to the western Indian Ocean, was firstly recorded in the Mediterranean Sea in 1994, and all Mediterranean populations discovered to date are related to shoreline areas. A total of ten fish farms were sampled off the coasts of Spain (4), Italy (1), Croatia (2), Greece (1) and Malta (2). This is the first time that C. scaura has been reported from off-coast areas. Reproducing populations have been detected in fouling communities of three tuna farms off the coast of Croatia and Malta, which also signifies the first confirmed record of this species in both countries. The occurrence of successfully established and thriving populations of C. scaura Templeton, 1836 at floating off-coast fish farms underlines the importance of these structures as stepping stones in the species.

“…They have been found to survive transport in ballast tanks (Carlton 1985) as well as dispersing over large distances as part of the fouling communities of sea-going vessels Astudillo et al 2009). In fact, the global distribution and introduction pathways of some invasive caprellid species can be attributed to these vectors (Caprella californica: AMBS 2002; Caprella mutica: Takeuchi and Sawamoto 1998;Ashton 2006;Ashton et al 2008;Caprella scaura: Krapp-Schickel et al 2006;Martí-nez and Adarraga 2008;Guerra-García et al 2011). Therefore, rafting on vessels, providing frequent opportunities for long-distance dispersal, is likely to be an important anthropogenic dispersal mechanism in C. andreae, which may also account for its wide geographic distribution.…”

Long-distance dispersal, low connectivity and molecular evidence of a new cryptic species in the obligate rafter Caprella andreae Mayer, 1890 (Crustacea: Amphipoda: Caprellidae)

et al. 2012

The amphipod Caprella andreae Mayer, 1890 was recorded for the first time in Southern Iberian Peninsula (36°44 0 15 00 N, 3°59 0 38 00 W). This species is the only obligate rafter of the suborder Caprellidea and has been reported to attach not only to floating objects such as ropes or driftwoods but also to turtle carapaces. Mitochondrial and nuclear markers were used to examine dispersal capabilities and population genetic structure of C. andreae across seven localities in the Mediterranean and Atlantic Ocean collected from floating substrata with different dispersal patterns. The strong population differentiation with no haplotypes shared between populations suggests that C. andreae is quite faithful to the substratum on which it settles. In addition, the proportionally higher genetic diversity displayed in populations living on turtles as well as the presence of highly differentiated haplotypes in the same turtle population may be indicative that these populations survive longer, which could lead C. andreae to prefer turtles instead of floating objects to settle and disperse. Therefore, rafting on floating objects may be sporadic, and ocean currents would not be the most important factor shaping patterns of connectivity and population structure in this species. Furthermore, molecular phylogenetic analyses revealed the existence of a cryptic species whose estimates of genetic divergence are higher than those estimated between C. andreae and other congeneric species (e.g. Caprella dilatata and Caprella penantis). Discovery of cryptic species among widely distributed small marine invertebrates is quite common and, in this case, prompts for a more detailed phylogenetic analysis and taxonomic revision of genus Caprella. On the other hand, this study also means the first record of the gammarids Jassa cadetta and Elasmopus brasiliensis and the caprellid Caprella hirsuta on drifting objects.

“…An established population of P. pusilla has recently been reported from northern Australia (Montelli and Lewis, 2008), possibly introduced via biofouling on vessels. In spite of having direct development, caprellids can also disperse over large distances by 'rafting' on detached aquaculture buoys and other natural or artificial floating structures (Thiel et al, 2003;Guerra-García et al, 2011).…”

Paracaprella pusilla Mayer, 1980 is a tropical caprellid amphipod species. It was first described from Brazil and is found to be very common along the Atlantic coast of Central America. Since its original description, P. pusilla has been found in prolific volumes at numerous widespread locations in tropical and subtropical seas around the world, and is primarily associated with fouling communities in harbors. A well established population of P. pusilla was recently found in Cádiz, southern Spain, which is both the northernmost collection and the first recorded finding of this species in European coastal waters. Ship fouling is the most probable vector for its introduction. The species was always found in association with the native hydroid Eudendrium racemosum (Cavolini, 1785) and appeared to display a mutualistic relationship with this host.
