“…The tail was composed of 27 pairs of finlets, with 8 longitudinal protruding rib-like supports. This description is consistent with those of the fellodistomatid trematode Bacciger bacciger (Ramón et al 1999). The smallest infected clam was 22 mm long.…”

“…In fact, the cercariae of this trematode were first described in the clam Venerupis decussata (L., 1758) in Arcachon, France, by Lespès (1857), who named it Cercaria lata. Different authors reported B. bacciger in different bivalves including D. trunculus (Veneridae, Donacidae, Pholadidae) (Ramón et al 1999), and the life cycle was proposed by Palombi (1934). After escaping from sporocysts parasitizing the bivalves' first intermediate host (presumably D. trunculus in the present study), cercariae penetrate and encyst as metacercariae in the amphipod Ericthonius difformis MilneEdwards, 1830 that may be eaten by fish (Atherina L. 1758) where they develop into adults in the digestive tract.…”

“…Identification among different species of the genus Donax can be tricky (Pereira et al 2012), but the dominant species for this global area appears to be the wedge clam D. trunculus L., 1758 (Ansell & Lagardère 1980, Ramón et al 1999. This suspensionfeeding infaunal bivalve lives on shallow bottoms of the Mediterranean Sea and colonizes low tidal levels of Atlantic shores, from the wash zone to −2 m. Reported abundances vary considerably amongst sites, from fewer than 10 to several hundred per m 2 (Mouëza & Chessel 1976, Fishelson et al 1999, Deval 2009, La Valle et al 2011.…”

“…As a trematode using D. trunculus as the first intermediate host, with sporocysts intruding into the gonads, visceral mass, and eventually the whole body, it can be assumed by comparison with other bivalves being similarly infected by other trematode species that B. bacciger (Jonsson & André 1992, Thieltges 2006, de Montaudouin et al 2012 will have a detrimental effect on its host. Ramón et al (1999) noted castration in 2.4% of a D. trunculus population in the Gulf of Valencia (Spain). Sudden periodic and complete extinction was also observed in California (USA) for populations of the bean clam D. gouldii Dall, 1921, with the suspicion of an interaction between trematode occurrence and other environmental pressures (Johnson 1968).…”

Wedge clams Donax trunculus inhabit high-energy environments along sandy coasts of the northeastern Atlantic Ocean and the Mediterranean Sea. Two sites were sampled monthly, one in Morocco (Mehdia), where the density was normal, and one in France (Biscarosse), where the density was very low. We tested the hypothesis that the difference in density between the sites was related to infection by the trematode parasite Bacciger bacciger. Identity of both the parasite and the host were verified using anatomical and molecular criteria. Parasite prevalence (i.e. the percentage of parasitized clams) was almost 3 times higher at Biscarosse. At this site, overall prevalence reached 32% in July and was correlated with the migration of several individuals (with a prevalence of 88%) to the sediment surface. After this peak, prevalence decreased rapidly, suggesting death of parasitized clams. The deleterious effect of B. bacciger on wedge clams was also supported by our calculations indicating that the weight of the parasite made up to 56% of the total weight of the parasitized clams. However, condition indices of trematode-free clams were also lower in Biscarosse than in Mehdia or other sites, suggesting that other factors such as pollutants or microparasites (Microcytos sp.) may alter wedge clam population fitness in Biscarosse.

Bivalve sanctuaries to enhance stocks along the Algarve coast of southern Portugal: A spatio‐temporal approach

Populations of marine bivalves are subject to large interannual fluctuations as a result of their sensitivity to unfavourable environmental conditions. These populations have a strong dependence on recruitment, which constitutes a risk to stock conservation and the sustainability of the commercially exploited species. Bivalve sanctuaries comprising no‐take areas can promote the restocking of large coastal areas as a result of the high fecundity and the potentially long‐distance larval dispersal of bivalves. The present study explores a novel spatio‐temporal approach to investigate suitable locations for bivalve sanctuaries, aimed at protecting and enhancing stocks along the Algarve coast in southern Portugal. In the context of small‐scale fisheries, bivalve dredging constitutes an important socio‐economic activity. Three bivalve species are targeted: the striped venus (Chamelea gallina), the donax clam (Donax trunculus), and the surf clam (Spisula solida). Data gathered from 36 bivalve fishing surveys conducted over three decades (1986–2015) were analysed using geostatistical methods, accounting for temporal and spatial autocorrelation to produce continuous prediction maps of species distribution for each survey. The approach taken permitted the use of all scattered historical data collected by different methods. The predictions were then used to summarize and illustrate the spatial distribution of species across time, in terms of average biomass, variability, and maximum potential biomass, and to delimit the areas as a function of the species persistence (recurrent, occasional, or rare). The temporal patterns through space were further investigated using empirical orthogonal function (EOF) analysis. The areas accounting for 80% of the species biomass were also estimated. Results of this set of analyses led to the proposal of locations for establishing bivalve sanctuaries, aimed at enhancing the stocks of commercial bivalve species in the long term. Such an innovative spatio‐temporal approach and management strategy is replicable in other fishing resources and geographic areas.
