Mussels are one of the most important bivalve aquaculture species in the asia-pacific region and are also widely used as biological indicators for monitoring marine environments. Research on mussel's blood lymphocytes is of great importance for further research on their immune response to pathogens, environmental stress (e.g. climate change, salinity etc.), and marine pollutants (heavy metals, pesticides etc).
Mussel blood lymphocyte studies require the mussel blood lymphocytes to be extracted by an extraction device. Mussel's blood lymph is located in its adductor muscle, and when blood lymph is taken, the adductor muscle cannot be cut off. The current method is to open mussels, insert the needle of a syringe into the adductor muscle, and extract the blood lymph from the adductor muscle of the mussel. The existing mussel blood lymph extraction method has the defects that the thickness of the adductor muscle is thinner, the needle head of the injector is not easy to control in the process of being inserted into the adductor muscle, and the needle head is easy to penetrate through the adductor muscle, so that the mussel blood lymph extraction fails.
