Primary production of macrophytes in estuaries of Primorye
Annual production of macrophytes in estuaries of the rivers Tesnaya, Gladkaya, Razdolnaya, Artemovka, Shkotovka, Sukhodol, Kievka, and Avvakumovka (Primorye region) is estimated from the data on their distribution, biomass and its seasonal dynamics obtained in 2008–2012. Primary production of the most common species varies in the range 60.0–902.1 gС/m <sup>2</sup> and production of multispecies vegetation — in the range 69.6–516.7 gС/m <sup>2</sup> or 5.0–196.0 gС/m <sup>2</sup> scaled to entire area of inner estuaries. Macrophytes themselves provide a high level of organic matter production in the estuaries of Primorye, even without taking into account other groups of primary producers.
