An approach to the study of the immunity functions of bivalve haemocytes: Physiology and molecular aspects

The Mediterranean mussel Mytilus galloprovincialis is an ecologically and economically important species. It has been used in programs of monitoring of pollutions, since it is sessile organism that is capable of accumulating pollutants in tissues through filter feeding. Due to an increase of pollutants in the environment, marine mussels present physiological alterations that compromise their … Continue reading An approach to the study of the immunity functions of bivalve haemocytes: Physiology and molecular aspects

Effect of infection with Metacercariae of Himasthla elongata (Trematoda: Echinostomatidae) on cardiac activity and growth rate in blue mussels (Mytilus edulis) in situ

Trematode parasites can affect their molluscan hosts, which serve as the first intermediate hosts in their life cycles, in manifold ways, but little is known about trematode-induced effects on their second intermediate hosts. Experimental infection of blue mussels Mytilus edulis serving as second intermediate hosts for larval stages (metacercariae) of the trematodes Himasthla elongata was … Continue reading Effect of infection with Metacercariae of Himasthla elongata (Trematoda: Echinostomatidae) on cardiac activity and growth rate in blue mussels (Mytilus edulis) in situ

Potential environmental drivers of a regional blue mussel mass mortality event (winter of 2014, Breton Sound, France)

In the context of global change, increasing mariculture production has raised particular concerns regarding its environmental impact and sustainability. Molluscs and particularly blue mussel account for a significant part of this total production. Although blue mussels are considered to be pretty resilient to environmental disturbances, we report in this study an unprecedented mussel mortality event … Continue reading Potential environmental drivers of a regional blue mussel mass mortality event (winter of 2014, Breton Sound, France)

Spillover but no spillback of two invasive parasitic copepods from invasive Pacific oysters (Crassostrea gigas) to native bivalve hosts

Invasive species can cause indirect effects on native biota by modifying parasite-host interactions and disease occurrence in native species. This study investigated the role of the invasive Pacific oyster (Crassostrea gigas) in potential spillover (co-introduced parasites infect native hosts) and spillback (native or established parasites infect invasive hosts and re-infect native hosts) scenarios of recently … Continue reading Spillover but no spillback of two invasive parasitic copepods from invasive Pacific oysters (Crassostrea gigas) to native bivalve hosts

The interaction between algal viruses and the mussel Mytilus galloprovincialis Lamarck, 1819 (Bivalvia: Mytilidae) in experiments

The utilization (possible assimilation and concentration in organs) of 99% of algal viruses from the water by the Black Sea mussel Mytilus galloprovincialis was confirmed experimentally. This index depends on the duration of the experiment, the complexity of the morphology of the virus, the age (size) of the mussels, and the presence of a nonindicatory … Continue reading The interaction between algal viruses and the mussel Mytilus galloprovincialis Lamarck, 1819 (Bivalvia: Mytilidae) in experiments

Species composition and genetic diversity of farmed mussels in British Columbia, Canada

The common blue mussel (Mytilus edulis) was introduced to British Columbia, Canada, in the 1980s as an aquaculture alternative to native mussel species. Since then, the mussel industry in Pacific Canada has expanded and includes operations utilizing traditional methods of broodstock selection based on visual qualitative and quantitative traits. The impacts of hatchery propagation on … Continue reading Species composition and genetic diversity of farmed mussels in British Columbia, Canada

Isolation of Vibrionaceae from wild blue mussel (Mytilus edulis) adults and their impact on blue mussel larviculture

The blue mussel (Mytilus edulis) is known as a robust bivalve species, although its larviculture appears to be highly susceptible to diseases. In this study, we isolated 17 strains from induced mortality events in healthy wild-caught blue mussel adults and demonstrated that they caused between 17% and 98% mortality in blue mussel larvae in a … Continue reading Isolation of Vibrionaceae from wild blue mussel (Mytilus edulis) adults and their impact on blue mussel larviculture
