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 microalga, which allows the experimental conditions to be close to natural and is conducive to the agglutination of viruses in pseudofeces and their enhanced utilization by mussels. It was found that some algal viruses concentrated by filter-feeding mussels return to the environment in the feces and are transported to the bottom (where they can be used by benthivores) or diffuse back into the pelagic zone. The results indicate that mussels have a role in the circulation of marine viruses, utilizing and transferring them from the pelagic to the benthic biotope.
