“…M. modiolus, also known as the horse mussel, lives 20-45 years on rocks, boulders, gravel, pebbles, and sand, sometimes being submerged 2-3 body lengths into the sediment [47,48]. C. grayanus and M. modiolus are closely related bivalve species of the family Mytilidae, which are commonly used for heavy-metal monitoring in coastal waters of the northwestern Pacific [49,50]. It was reported that, despite a higher level of heavy metal accumulation, M. modiolus has a defense strategy that includes gradual detoxification and excretion of the pollutants from the organs [50].…”

The defense system of C. grayanus was reported as ineffective under chronic pollution because of the high load of heavy metals in the digestive gland and kidney [50].…”

A. boucardi is a bivalve of the family Arcidae, which lives on sand or rock-boulder bottom, often forming a joint biocenosis with C. grayanus [51].…”

Nanoparticles (NPs) have broad applications in medicine, cosmetics, optics, catalysis, environmental purification, and other areas nowadays. With increasing annual production of NPs, the risks of their harmful influence on the environment and human health are also increasing. Currently, our knowledge about the mechanisms of the interaction between NPs and living organisms is limited. The marine species and their habitat environment are under continuous stress owing to the anthropogenic activities, which result in the release of NPs in the aquatic environment. We used a bioassay model with hemocytes of three bivalve mollusc species, namely, Crenomytilus grayanus, Modiolus modiolus, and Arca boucardi, to evaluate the toxicity of 10 different types of NPs. Specifically, we compared the cytotoxic effects and cell-membrane polarization changes in the hemocytes exposed to carbon nanotubes, carbon nanofibers, silicon nanotubes, cadmium and zinc sulfides, Au-NPs, and TiO2 NPs. Viability and the changes in hemocyte membrane polarization were measured by the flow cytometry method. The highest aquatic toxicity was registered for metal-based NPs, which caused cytotoxicity to the hemocytes of all the studied bivalve species. Our results also highlighted different sensitivities of the used tested mollusc species to specific NPs.

“…At the same time, a high concentration of metallothionein like proteins, which bind not only Cd but also other heavy metals, was detected in the kidneys of the mus sels that were collected from the area with strong sta tionary upwelling (waters off Iturup Island); this shows the adaptation of the bivalves to extremely high accu mulations of these metals [10]. In the mollusks from the polluted area (Desantnaya Bay), the protective detoxification system was, in contrast, suppressed as a result of the combined effect of accumulated metals [11,12], which is also confirmed by the significant accumulation of lipid peroxidation products in the organs of the mussels from these stations [4].…”

The influence of habitat conditions on the activity, the structure of the substrate specificity (the ratio of the substrate hydrolysis rates), and the kinetic parameters of substrate hydrolysis due to the effect of hemolymph cholinesterase of the mussel Crenomytilus grayanus was studied. Mussels were collected from areas that are influenced by seasonal and stationary upwelling, as well as from a polluted area. Upwelling and anthropogenic pressure were shown to alter the structure of hemolymph cholinesterase substrate specificity in mussels, up to complete loss of the ability to catalyze the hydrolysis of propionyl and butyrylthiocholine. It was established that during the seasonal upwelling the efficiency of the cholinergic process in mussels is provided by a wide range of effective concentrations of the substrates and by decreasing their affinity to the enzyme. Under the conditions of chronic anthropogenic pollution, the cholinesterase of the mussel hemolymph loses its ability to hydrolyze substrates other than acetylthiocholine.

“…Studied in this work, M. kurilensis is one of the dominant species of zoobenthos in the shallow and infralittoral zones of the Sea of Japan. Therefore, mollusks from genus Modiolus are often used as test objects in biomonitoring studies [20][21][22][23][24]. Due to its high biological value, Modiolus is also caught as a bycatch for Crenomytilus grayanus Dunker, 1853 (Mytilida: Mytilidae) and goes along with it for the production of canned food [25,26].…”

The invasion of bivalves by parasitic microalgae Coccomyxa is widespread and causes pathologies and dysfunctions of the organs, especially in the most valuable products: the mantle and the muscle. The pathogenesis of the disease remains completely unknown. In this study, based on a macroscopic examination of Modiolus kurilensis and microalgae count in each infected individual, four stages of disease development with characteristic pathognomonic symptoms were described. During the progression of the disease, the concentration of alkaline phosphatase, glucose, calcium, hemolytic and agglutinating activities, number of basophils, eosinophils, phagocytes, and cells with reactive oxygen species increased in the hemolymph, while number of agranulocytes, cells with lysosomes, dead hemocytes, total protein concentration, as well as the weight of mollusks decreased. In the nephridia and digestive gland, necrosis, invasion of Nematopsis sp., hemocyte infiltration, and fibrosis increased. The ratio of changed tubules and occurrence of granulocytomas increased in the digestive gland, while the base membrane, nephrocytes and concretions changed in the nephridia. This study helps establish the variability of these parameters under normal conditions and their alteration during the disease. Moreover, these findings can be used for veterinary monitoring of the state of bivalves in natural and aquaculture populations.
