Filtration activity of mollusks Mya arenaria L. (Bivalvia) in estuaries of the southern Baltic Sea
This article argues that, in the estuaries the South Baltic, the bivalve molluscs Mya arenaria are capable of consuming an average of 6.5 % of the water body primary production. A numerical assessment of the filtration rate of these molluscs shows that they can filter daily an average ...
Phytoplankton production and chlorophyll content in different types of estuaries
This article focuses on the results of many years’ research on phytoplankton production and chlorophyll concentration in estuaries of different types (the Vistula and Curonian Lagoons, and the Volga delta). A comparison with hydrological and chemical parameters helped identify the main factors determining the level of primary production and eutrophication. The productivity ...
