“…The shortest ovigerous female was 5.64 mm long with 5 eggs in the brood pouch; the longest reached 9.57 mm and carried 62 eggs. There was a positive correlation between female length and number of eggs of C. scaura, also found for C. mutica and other caprellids in previous studies (Caine 1979, Vassilenko, 1991; this feature is a common trend in amphipods (SainteMarie 1991, Prato andBiandolino 2006).…”

“…Fecundity of caprellids varies seasonally, being a function of female size (Vassilenko 1991). Female caprellids breeding in spring were much larger and more fecund than those breeding in summer (Vassilenko 1991). Bacela et al (2009) underlines that the invasive species are characterized by very high fecundity, fast growth and attaining the maturity early.…”

SUMMARY:Caprella scaura is an epifaunal amphipod crustacean that originates in the western Indian Ocean and has spread throughout the world, but very little is known about fundamental aspects of its biology. This paper is the first presentation of its life history traits in an invaded region. The study was conducted in the Mar Piccolo basin (southern Italy, Ionian Sea), over a one-year period. All biological parameters showed a strong seasonal pattern, breeding peaked twice during the year and the number of eggs in the ventral brood pouch ranged from 5 to 72. The sex ratio was generally close to 1:1. A strong correlation between total length of ovigerous females and number of eggs was observed. The mean length of both mature males and mature females was 10.63 and 7.70 mm, respectively. The results of this study showed that the population dynamics of this species was not dissimilar to that of other caprellids or marine epifaunal Crustacea. This caprellid has given rise to a stable population in the Mar Piccolo; it was present all year round in the study area but its density suggests that it is not yet a strong invader.

“…The native habitat of C. mutica is the sub-boreal coastal waters of north-east Asia, but it has now been described from all oceanic coastlines in the northern hemisphere (Ashton et al 2007a), and from New Zealand in the southern hemisphere (Inglis et al 2006). The population and production biology of C. mutica in its native range in Possjet Bay, Sea of Japan has been investigated by Fedotov (1991) and Vassilenko (1991). However, given the widespread distribution of non-native C. mutica, it is necessary to understand its ecology and biology in non-native habitats.…”

Abstract. Information on the life history and population dynamics of non-native species is essential to understand the process of invasion and impacts on invaded ecosystems. The non-native marine caprellid amphipod Caprella mutica has successfully established populations on coastlines throughout the temperate northern hemisphere and in New Zealand in the southern hemisphere. The introduction mechanism has been surpassed and it is now important to understand its ecology and biology in non-native habitats. The seasonal population dynamics of C. mutica were investigated over 18 months at four sites with different levels of anthropogenic disturbance on the west coast of Scotland. Abundance of C. mutica fluctuated seasonally at all sites, peaking during June to October. The highest abundance recorded on a single mesh collector was 319 000 individuals m À2 in August 2004 at one of the fish farms. Both seasonal and site-specific factors influenced the population dynamics of C. mutica. Both males and females were significantly larger and more abundant at the fish farm sites. Individuals displayed reproductive characteristics at a smaller size at the fish farm sites, indicating earlier maturity. The results suggest that anthropogenic disturbance and artificial resource enhancement contribute to the global establishment success of non-native C. mutica.

“…In its native habitat, C. mutica is found associated with attached macroalgae and drifting seaweeds, including Sargassum spp., and on aquaculture structures, such as ropes for Undaria culture in Otsuchi Bay (Kawashima et al 1999 (Fedotov 1991, Ashton 2006, although, the maximum number of recorded hatchlings produced by a single female is 82 (Cook et al 2007). There is a positive correlation between fecundity and female body length (Vassilenko 1991). …”

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.
