Title: The Curonian Lagoon: two hundred years with the zebra mussel 
/Dreissena plymorpha/

Speaker: *Anastasija Zaiko*, Coastal Research and Planning Institute

Abstract
The Curonian Lagoon, a large shallow (mean depth 3.8 m) and nearly 
freshwater body situated in the south-eastern part of the Baltic Sea, 
was invaded by several Ponto-Caspian Species in the beginning of the 
19th century after the water link between the Nemunas and Dnepr rivers 
was established. The invasion of the zebra mussel /Dreissena polymorpha 
/had the most pronounced effect on the Curonian Lagoon ecosystem. The 
impact can be traced at different levels: from a local bottom community 
to the biogeochemical cycle of the whole ecosystem.

The zebra mussel, as a main habitat forming animal species, to a great 
extent determines the taxonomic and functional guild structure of the 
local bottom communities. Its community covers about ¼ of the lagoon’s 
bottom. The area covered by its shell deposits is even larger. The 
highest macrozoobenthos diversity is found there. There is also a 
gradient in species composition detected moving from bare sediments 
through shell deposits and towards the living zebra mussel community.

An invasibility analysis of different habitats within the Lithuanian 
offshore and coastal waters indicated that the most invaded habitats are 
those modified by zebra mussel or its shell deposits.

Another aspect of zebra mussel effect – its impact on the material flow 
at the ecosystem scale. The /D. polymorpha/ clearance and biodeposition 
rates are interpolated to the entire Lagoon ecosystem using experimental 
and modeling approach.
