Suitable fish hosts for glochidia of three freshwater mussels: strange floater, ellipse, and snuffbox.
Now, in these first decades of the twenty-first century, something is decidedly off: researchers speculate that it might be water temperature changes in streams and reservoirs or pesticides impacting the glochidia or alterations in fish migration patterns.
In the early stages of development (glochidia and juveniles), unionid mussels are prone to bacterial infectious diseases (Grizzle & Brunner 2009).
Biologists with the Service's Southwestern Virginia Field Office, Virginia Field Office, Kentucky Field Office, Virginia Department of Game and Inland Fisheries, Virginia Tech, Kentucky Department of Fish and Wildlife Resources, and The Nature Conservancy worked cooperatively and quickly this past March to extract the glochidia and return the females unharmed back to Indian Creek.
Tiny glochidia (larvae) form within four to six weeks.
Released from the gills of an adult mussel into the water no bigger than grains of sand, the glochidia require a host for the several weeks it takes them to metamorphose into tiny mussels able to live on their own.
The fertilized eggs develop into the larval form (glochidia) in a specialized part of the gills, the marsupium.
When embryonic development is complete, the larvae, which are also called glochidia, are released from the adults and attach primarily to the gills or fins of fish (Barnhart et al., 2008).
triquetra (Zanatta and Murphy, 2008 and references therein), and the mussel has evolved a unique strategy of capturing the fish to infest it with glochidia (Barnhart et al., 2008).
They begin as larvae, or glochidia as they are called.
This summary makes good use of more than 75 laboratory studies of glochidia juvenile mussels to analyze damage from contaminants on freshwater ecosystems, and also gives a framework practitioners can use to establish priorities in rehabilitation and management.
