“…Three species of the genus Marteilia, viz. M. refringens (Villalba et al 1993), M. cochillia (Villalba et al 2014) and M. octospora (Ruiz et al 2016), occur in Galicia, including the Ría de Arousa where the 2 lagoon cockles infected with a Marteilia-like parasite were found. Even if M. cochillia was the species infecting those 2 lagoon cockles, C. glaucum should be considered resistant to M. cochillia since no case of advanced infection with fully developed parasites was detected (only 2 out of 520 individuals were lightly infected with immature parasite stages).…”

“…data), leading to the disappearance of live common cockles C. edule from that shellfish bed; conversely, this parasite was not found in lagoon cockles C. glaucum in any monthly sample, from December 2012 to December 2013, in that bed. The epidemic outbreak of M. cochillia in 2012 caused the common cockle C. edule fishery to collapse in the Ría de Arousa (Villalba et al 2014), with subsequent outbreaks in the rias of Pontevedra and Vigo, devastating common cockle C. edule beds there as well (authors' unpubl. data).…”

“…Historically, C. edule has largely been more abundant and has been the main component of exploited stocks, although both species appeared mixed in the official statistics of captures, simply named 'cockles'. In 2012, mass mortality of the common cockle C. edule, caused by the protistan parasite Marteilia cochillia, occurred in the Ría de Arousa, one of the most productive cockle-growing areas of Galicia, leading to cockle fishery collapse in this ria and, thus, a huge decrease in Galician cockle landings (Villalba et al 2014). Since then, newly recruited common cockles have also become infected with M. cochillia, which has impeded C. edule fishery recovery (authors' unpubl.…”

A histopathological survey revealed parasites and pathological conditions affecting lagoon cockles Cerastoderma glaucum along the Galician coast; serious pathological threats were not detected because the potentially pathogenic conditions (infections with a Marteilia-like parasite and bucephalid sporocysts, disseminated neoplasia and a condition involving large foci of heavy haemocytic reaction) were rare, while more prevalent parasites had negligible or limited pathogeny. Considering that C. edule and C. glaucum are sympatric in some Galician rias, it is remarkable that C. glaucum was not seriously affected by Marteilia cochillia while C. edule suffered an intense outbreak of this parasite associated with massive mortality. Comparison of the digestive gland between cockle species showed co-occurrence of digestive tubules in different phases, with abundant disintegrated tubules, in the case of C. glaucum, while C. edule showed synchronicity and absence of fully disintegrated tubules; these differences could in fluence their susceptibility to M. cochillia because the main location of this parasite in common cockles is the epithelia of the digestive gland. Moreover, the observation of histological sections through the digestive gland easily allows differentiating the 2 cockle species.

Predation risk increases in estuarine bivalves stressed by low salinity

et al. 2021

Salinity drops in estuaries after heavy rains are expected to increase in frequency and intensity over the next decades, with physiological and ecological consequences for the inhabitant organisms. It was investigated whether low salinity stress increases predation risk on three relevant commercial bivalves in Europe. In laboratory, juveniles of Venerupis corrugata, Cerastoderma edule, and the introduced Ruditapes philippinarum were subjected to low salinities (5, 10 and control 35) during two consecutive days and, afterwards, exposed to one of two common predators in the shellfish beds: the shore crab Carcinus maenas and the gastropod Bolinus brandaris, a non-indigenous species present in some Galician shellfish beds. Two types of choice experiment were done: one offering each predator one prey species previously exposed to one of the three salinities, and the other offering each predator the three prey species at the same time, previously exposed to one of the three salinities. Consumption of both predators and predatory behaviour of C. maenas (handling time, rejections, consumption rate) were measured. Predation rates and foraging behaviour differed, with B. brandaris being more generalist than C. maenas. Still, both predators consumed significantly more stressed (salinity 5 and 10) than non-stressed prey. The overall consumption of the native species C. edule and V. corrugata was greater than that of R. philippinarum, likely due to their vulnerability to low salinity and physical traits (e.g., thinner shell, valve gape). Increasing precipitations can alter salinity gradients in shellfish beds, and thus affect the population dynamics of harvested bivalves via predator–prey interactions.
