Freshwater mussels are mollusks and are similar to their marine clam and oyster cousins. If the mussel is lucky enough to grow into an adult, it may live 20-100 years or more depending on the species. The app has a key that allows someone to answer a selection of yes-and-no questions to determine the species, using the GPS signal in that person’s phone to help narrow down the potential species. Species richness of freshwater mussels in the west and northwest is generally low (Figure 2-2-i, Table 2-2-i), but five of the six species of freshwater mussels in British Columbia are found nowhere else in Canada. Wilder Future. WSNFH held back several species (approximately 25 mussels), as of January 2008, 12 were is alive and doing well (48% survival after 7 years in refugia).  While the mussels were held at WSNFH, propagation techniques were developed, glochidia were collected from several species and transformed juveniles were collected and kept alive for six months and studied. Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. “People don’t have to do that; they can choose whether they want to report. Australia has 18 species of mussels, most of which are found nowhere else in the world. Join the Wildlife Trusts on our exciting adventure to a Wilder Future. • Araujo, R & Moreno, R. 1999.  A number of studies have been performed at WSNFH, to identify the particular host fish for certain mussels (i.e., Elliptoideus sloatianus (Purple bankclimber), Quadrula infucata (Sculptured pigtoe),   Hamiota subangulata (Shine-rayed pocketbook), Villosa vibex (Southern rainbow), and Villosa lienosa (Little spectaclecase).  This information is important for conservation efforts, since reintroductions and augmentation of mussel populations will only be successful if the mussel’s host fish is present in the same areas as the mussel. Freshwater mussels and snails are members of the phylum Mollusca, invertebrate animals with a soft body that is enclosed wholly or in part in a mantel and a shell.

Similar Species Several of the large freshwater mussels look similar and can be easily confused, particularly with smaller specimens. For each species, there is a detailed list of characteristics, tips for identifying them, a number of photos of the outside and inside of the shells and a distribution map. Worldwide in distribution, they are most common in cool seas. In 2012, Todd Morris and his lab developed the Canadian Freshwater Mussel Guide.

Pollutants and altered river flows threaten many freshwater mussel species. The basin is currently home to 29 species of mussels.  The WSNFH has become involved in determining potential fish host species for imperiled mussels. “We offer an identification workshop every year, so we were looking for a tool for people to identify specimens out in the field after they left us, after the workshop.”, The Toronto Zoo and Fisheries and Oceans Canada’s Clam Counter app. Freshwater mussels are the most imperiled wildlife in the world. A freshwater fishing license is required to take any freshwater mussel species. Freshwater mussels are vital components of stream ecosystems, yet remain threatened. “There’ve been a bunch of other species-identifier apps that had been developed and with there being so many American mussel species, we thought it might be a good idea to have one for mussels and provide outreach for the various North American mussel species that we’ve got,” said Susan Rogers Oetker, the app coordinator for the Freshwater Mollusk Conservation Society. Diplodon, as currently classified, is the sole Recent genus of the Tribe Rhipididontini. The discovery of this mussel-leech association has wider ranging importance because freshwater mussels are one of the most imperiled animal groups worldwide, revealing the fastest rates of extinction. The app has origins with a lot fewer cutesy illustrations and simple interactive questions. Like our native salmonids, freshwater mussels are declining due to habitat degradation and fragmentation caused by dams, water pollution, and reduced streamflow.

Freshwater mussels, the vacuum cleaners of the aquatic ecosystem, feed by filtering algae and small particles from the water. The Apalachicola-Chattahoochee-Flint River Basin (ACF) supports one of the most diverse freshwater mollusk assemblages in the Southeast United States.  Historically, the ACF had at least 14 genera and 33 species with six species being unique to the basin.  Over the past decade, numerous surveys were conducted in the ACF and concluded that only 29 native mussels currently exist within the ACF.

Several described methods include producing glochidia in bundles that resemble food items (conglutinates), producing superconglutinates of glochidia that are attached to the mussel by a long mucus string to mimic prey fish, discharging glochidia in a mucus web, modification of mantle flaps in the females to mimic small fish, and releasing glochidia into the water column. Slugs, snails and freshwater mussels Species. The four species of mussels sampled were the European blue mussel, the greenshell mussel, the undulate venus, and the Pacific venus clam. Since 2000, WSNFH has been conducting mussel propagation studies.  In the early days three species of mussels were used with successful results: Hamiota subangulata (Shine-rayed pocketbook) produced 5,582 mussels, Villosa vibex (Southern rainbow) produced 2,627 mussels, and Villosa lienosa (Little spectaclecase) produced 940 mussels.  All juvenile mussels were released in three different locations within Spring Creek after six weeks of growth.  Over 700 species of snails and 300 species of freshwater mussels have been described by scientists so far.

Back in the late 1990’s, South Georgia was experiencing one of the longest droughts in recorded history, many streams became completely dry and several rivers were at lowest levels in years.  The WSNFH was asked to assist in savage operations in the summer of 2000 in Spring Creek, a tributary of the Flint River, there mussels became isolated to specific reaches within the stream.   Approximately 1,375 live mussels were transported to WSNFH to be held in refugia until conditions in the stream improved.  A total of 1050 mussels were returned to their original habitat in Spring Creek on June 5, 2001 (71% survival for 1-year in captivity).  All mussels returned to the creek were tagged for future survival studies. Of those 300 species 70% are either extinct, endangered, threatened, or of special concern at either the state or federal level. For the most part the sixteen dams on the Chattahoochee and Flint rivers have long-term negative impacts. Freshwater mussels are under threat and are declining, both in New Zealand and worldwide.  The available information concerning listed mussel species and their relationships with host fish is limited.   Therefore, identifying host fish for imperiled freshwater mussel species is critical in conservation efforts.   Identification of host fish can be determined through artificial infection in the laboratory using an array of techniques.  These techniques are vital for the conservation and propagation of freshwater mussels.
