Summary of InvasivenessTop of page
At the end of the nineteenth century, C. fornicata was accidentally introduced in Europe where it found favourable conditions to settle and develop: free surfaces of sandy-coarse sediment, optimal water temperature range, copious suspended organic matter as food and no specific predators; all this contributed to a rapid growth and reproductive success.
Oyster farming is the main cause of introduction and dispersal. Dredging and trawling of the oyster-growing areas has contributed to the spatial spread of C. fornicata. It is now demonstrated that these fishing practices have, for decades, played a main role in the spread.

DescriptionTop of page
C. fornicata is a marine gastropod with a brown shell. Individuals reach about 6 cm long. The septum divides the interior of the shell into two parts: the external one where the foot and head can move and the internal one where the visceral mass is protected. Growth is rather rapid and a size of 2 cm is reached in 2 years. The plasticity of this species is important and shell can be deformed.
The first particularity of this species is that the individuals gather under attractive substances and form colonies, called ‘chains’. Individuals settle on top of each other, forming clusters. Only one juvenile remains at the top of the stack, the others move to form a new colony. The population extends in three dimensions.
In a standard colony there are 5 or 6 individuals, but in dense populations, this creates amazing numbers of stacks with complex colonies where the juveniles attach anywhere and support a new chain.
Newel and Kofoed (1977) described the morphology of the feeding system and measured the feeding rates in C. fornicata. This ubiquistous species ingests a wide variety of organic and inorganic food, at a rate of about 1 litre h-1 g-1, and also ingests some of its own larvae (Pechenik et al., 2004). The pelagic larva is also able to filter a wide range of particles (Blanchard et al., 2008). The radula can also capture some deposited matter. This feeding mode helps it find sufficient food to develop large populations, contrary to other grazing patellids (Hoagland, 1977).
Being fixed, the animals have developed a particular reproduction. The species is protandric. Juveniles are males and individuals become rapidly hermaphrodites from the second year, and then are females during the rest of their life (10 years). Between males and females of the same stack, fecundation is direct and sperm can be stored in a receptacle. Females of 2 cm long can be ovigerous. The brood is protected, eggs are laid grouped in bags (about 50 eggs bag-1) and are first stored near the head and later fixed on the lower shell. After about a month, each female releases 10-20,000 free larvae. They are veliger, barrel-shaped with a central ring of filaments to move in the plankton. Their size (min. 400 µm) and their strength make them suitable for experimental use (Pechenik and Lima, 1984; Pechenik et al., 2002b, 2004). The pelagic phase is about 3-weeks long (depending of the temperature) then larvae metamorphose and fall to the bottom where they look for suitable supports. All kinds of hard material can be used but they prefer a congener shell.
Being ubiquitous, eurythermic and euryhaline, this species can be observed in all kinds of environments: rocky, gravel or sandy bottoms, as well as in muddy areas where are measured the highest densities in Europe. These characteristics have helped it to spread so successfully.
DistributionTop of page
The geographical distribution of C. fornicata now stretches over 24 degrees of latitude, reaching all European seasides and the English Channel which currently appears to be the most colonized area (Blanchard, 1997). It is currently limited to the northern hemisphere. In the western USA, it was imported with oysters in Puget Sound during the 1930s, and is now common along the Washington state coastline (Hoagland, 1974, 1977). In 1968, spreading populations were noted in the bays of Tokyo and Sagami in Japan (Habe and Maze, 1970).

Impact SummaryTop of page
ImpactTop of page
Economic ImpactTop of page
The activities which have fallen victim to C. fornicata such as dredging or trawling, and shellfish-farming especially oysterfarming, are those which, for less than a hundred years, contributed, accidentally or not, to its spread. Dense limpet populations disturb fishery or oyster farming activities to such an extent that in some bays (Sheldt estuaries in Zeeland, Thames estuary and Fal River (Fitzgerald, 2007) in Great Britain, the Norman gulf or the Atlantic Marennes pond in France, cleaning operations are necessary. Regularly, oyster grounds must be cleaned before sowing new seed or when the C. fornicata populations create a too large negative effect. When limpets are fixed on oysters, oyster farmers must pick off limpets before selling the products, which creates an extra economic burden (Blanchard, 1997).
Expensive treatment methods have been developed, often without success. Public spending is constantly increasing. Yet applying the regulations or laws at the earliest observations would suffice to halt this spread. We are now observing in dense areas, the consequences of insufficient surveillance and precautions during the importation period.
