| description | The decline of freshwater pearl mussel (Margaritifera margaritifera L.)
populations is globally well documented, but there is a lack of knowledge concerning the
status of the species and its interaction with host fishes in the rivers of the White and
Baltic Seas. This study aimed to identify the host fish of pearl mussel in four rivers of
Karelia (Northwest Russia), to analyse the duration of the parasitic phase, and the
susceptibility of fish hosts to the infestation. Juvenile sea-migrating and land-locked
Atlantic salmon (Salmo salar L.) were identified as the most important
hosts. In the Keret’ River, reduced numbers of juvenile Atlantic salmon are likely to
result in a decline of pearl mussel. This problem does not appear to be present for the
other three studied rivers. Pearl mussel glochidia were mostly found in yearlings
(0+), whereas older fish
were infected less, suggesting a more complex pattern of host use than commonly expected.
The remote location of Karelian pearl mussel rivers, the high number of pearl mussels in
them, and their rather pristine state all suggest that these rivers have a high
conservation priority. The importance of Atlantic salmon as a host fish and the emerging
declines of Atlantic salmon populations, e.g., in the Keret’ River,
suggest that the sustaining of this host species should have a high conservation priority. |
