Systems: Freshwater
Continuing decline in area, extent and/or quality of habitat: Yes

Threats [top]

Major Threat(s): The lake is suffering rapid eutrophication as the result of agricultural activities and pollution from domestic sewage.  There is also offtake of water from parts of the lake for domestic supplies in the towns adjacent to the lake.

Conservation Actions [top]

Conservation Actions: No conservation actions in place for the species. Lake Skadar has some ecosystem management plans in place, however, this species requires habitat management to maintain the ecosystem in view of the possible lake-level changes and eutropication, as it  lives in the littoral part of the lake between the emergent and floating vegetation.  Survey-work is required to establish the number of subpopulations in Albania.
