Seasonal dynamics of some biochemycal parameters of Gray mussel
Seasonal dynamics of the fractional composition of soft tissue proteins of mussels was studied. A high variability in the content of water-soluble proteins in different seasons has been established. The multidirectional seasonal dynamics of muscle fibers protein fractional composition was shown. The decrease hemolymph protein concentration in the summer-autumn period was shown. Increase of mussels hemolymph cholinesterase activity in autumn was ascertained upto 2,6 U / mg. Activity of acidic proteinases in the hemolymph of Gray mussel was determined for the first time.
