ABSTRACT A large caprellid amphipod recently discovered at a salmon farm in the Lynne of Lorne near Oban, Scotland, has been identified as Caprella
mutica, a species indigenous to north-east Asia. The caprellid population appears to have become established in the last four years at the site with a high abundance of animals occurring year round on the farm nets, mooring ropes and on artificial experimental structures located <10 m from the fish farm. This paper briefly describes C.
mutica found in Scotland. Application of Chapman & Carlton's criteria for determining introduced species suggests that C.
mutica is non-indigenous to the area.

    • "Ciona is a notorious invasive species that has highly impacted aquaculture in PEI (and elsewhere in the world (Millar 1958; Kang et al. 1978; Uribe and Etchepare 1999; Tan et al. 2002) and has been a focus of management effort since its arrival there in 2004 (Locke et al. 2007). C. mutica is less problematic, and in spite of its global success as an invasive species (Willis et al. 2004; Bushbaum and Gutow 2005; Ashton et al. 2007; Locke et al. 2007), it has received little attention, both in PEI [where it was first noted in 1997 (Locke et al. 2007)] and elsewhere. Before our study, little was known about the predatory potential of C. mutica, and although it was suspected to be important (Epelbaum et al. 2009), only very recent work has confirmed that they are able to feed on tunicate larvae in the laboratory (Rius et al. in press).

    ABSTRACT: As the number of introductions of non-indigenous species (NIS) continues to rise, ecologists are faced with new and unique opportunities to observe interactions between species that do not naturally co-exist. These interactions can have important implications on the invasion process, potentially determining whether NIS become widespread and abundant, survive in small numbers, or fail to establish and disappear. Although many studies have naturally focused on the interactions between NIS and native species to examine their effects and the biological resistance of the recipient community to invasion, few have examined the effects that NIS have on each other. In some cases, interactions can facilitate the invasion process of one or both species (i.e., “invasional meltdowns”), but competition or predation can lead to negative interactions as well. The introduction of the vase tunicate, Ciona intestinalis, in Prince Edward Island (Canada) has harmed mussel aquaculture via heavy biofouling of equipment and mussels. Through both a broad-scale survey and small-scale field experiments, we show that Ciona recruitment is drastically reduced by caprellid amphipods, including the NIS Caprella mutica. This study provides an exciting example of how established invasive species can negatively impact the recruitment of a secondary invader, highlighting the potential for non-additive effects of multiple invasions.

    ABSTRACT: Paracaprella pusilla Mayer (Fauna und Flora des Golfes von Neapel 17:1–55, 1890), originally described from Brazil, is one of the most abundant caprellid amphipod species in tropical and subtropical seas around the world. During a survey of caprellid amphipods from marinas along the Balearic Island (Western Mediterranean Sea) carried out between November 2011 and August 2012, we found two established populations of P. pusilla in Mallorca and Ibiza, respectively. So far, its occurrence in European waters was reported only from southwestern Spain in 2010. This record represents a northward range expansion of the species’ distribution, which is found for the first time in the Mediterranean. This is also the first record of the genus Paracaprella in the Mediterranean Sea. The most probable introduction vector was ship fouling. We also found the invasive caprellid Caprella scaura Templeton (Trans Entomol Soc Lond 1:185–198, 1836) in Mallorca and Menorca, which is recorded for the first time in the Balearic Islands, confirming its rapid expansion along the Mediterranean. When comparing reproductive traits between both alien species, we found that P. pusilla has a higher fecundity than C. scaura for the same female size. Taking into account this evidence, the species may be expected to appear in other Mediterranean and adjacent areas.

    ABSTRACT: Relatively few non-native species are known from coastal ecosystems at high latitudes to date. We examined the fouling community in Alaska for the presence of the marine amphipod Caprella mutica, which is native to the northwestern Pacific Ocean and has invaded many different global regions. Between 2000 and 2007, fouling panels were deployed in 6 sheltered, shallow bays in Alaska. C. mutica were detected on panels at 4 of these bays, ranging from southeastern Alaska (Ketchikan) to the Aleutian Islands (Dutch Harbor), and have been present in Alaska for at least 6 yr. This appears to be the first reported occurrence of a non-native marine species in the Aleutians and also the first confirmation that a non-native crustacean has established self-sustaining populations in Alaska. These data contribute to growing evidence that coastlines in Alaska are susceptible to biological invasions.
