“…Host fish collection and care.-Based on the results of previous studies (Zale and Neves 1982;Yeager and Saylor 1995), Black Sculpin Cottus baileyi were used as the host fish for the Cumberlandian combshell and oyster mussel, and Largemouth Bass Micropterus salmoides were used as the host for the wavy-rayed lampmussel. Black Sculpin were collected using a backpack electrofisher (Model LR24, Smith-Root, Vancouver, Washington) and Largemouth Bass were obtained from a regional fish farm in Arkansas.…”

The effects of temperature on growth and survival of laboratory‐propagated juvenile freshwater mussels of two federally endangered species, the Cumberlandian combshell Epioblasma brevidens and oyster mussel E. capsaeformis, and one nonlisted species, the wavy‐rayed lampmussel Lampsilis fasciola, were investigated to determine optimum rearing temperatures for these species in small water‐recirculating aquaculture systems. Juveniles 4–5 months old were held in downweller buckets at five temperatures. Growth and survival of juveniles were evaluated at 2‐week intervals for 10 sampling events. At the end of the 20‐week experiment, mean growth at 20, 22, 24, 26, and 28°C was, respectively, 0.75, 2.22, 3.27, 4.23, and 4.08 mm for Cumberlandian combshell; 1.35, 3.73, 3.81, 4.90, and 4.70 mm for oyster mussel; and 2.09, 3.96, 4.99, 5.13, and 4.87 mm for wavy‐rayed lampmussel juveniles. Generally, temperature was positively correlated with growth of juveniles. Final mean maximum growth occurred at 26°C for all three species, although no significant differences in growth were detected between 26°C and 28°C. The relationship between temperature and survival of juveniles was less clear. Final survival was 82.5, 89.0, 91.0, 89.5, and 93.5% for Cumberlandian combshell; 73.0, 83.5, 78.0, 78.0, and 68.1% for oyster mussel; and 75.0, 89.5, 87.0, 86.5, and 89.5% for wavy‐rayed lampmussel juveniles at the five temperature treatments, respectively. Based on the species used in this study, results indicate that 26°C is the optimum temperature to maximize growth of juvenile mussels in downweller bucket systems. The ability to grow endangered juveniles to larger sizes will improve survival in captivity and upon release into the wild and will reduce time spent in hatcheries. As a result, hatcheries can increase their overall production and enhance the likelihood of success of mussel population recovery efforts by federal and state agencies, and other partners.

“…Watters (1994) summarized research focusing on freshwater mussel reproduction and propagation, and various studies have since focused on host determination for a broad range of species (Hove and Neves 1994;Yeager and Saylor 1995;Haag and Warren 1997;O'Dee and Watters 2000;Rogers et al 2001;Jones et al 2004;Eads et al 2006;Johnson et al 2012). The evolutionary rationale behind these relationships is largely unknown, as are specific details; thus, much is yet to be discovered about mussel-host relationships.…”

The Mussel–Fish Relationship: A Potential New Twist in North America?

North American freshwater mussels are critically imperiled organisms that generally require fish hosts in order to complete their life cycle. Although numerous studies have focused on the parasitic relationship between mussels and fishes, few have examined the benefits that mussels provide to other organisms. During sampling of Altamaha River, Georgia, we observed foreign eggs occurring within body cavities of native mussels across a 253‐km reach of the river basin. Eggs were recovered from 6% of the 757 mussels examined among seven sites. Foreign eggs were present in 17% and 18% of examined mussels at two sites. Using molecular techniques, eggs were identified as American Shad Alosa sapidissima. This discovery appears to be the first documented occurrence of native fish eggs in live North American mussels. Further research into the nature and mechanism of this symbiosis is warranted to assess whether this relationship is amensalistic, mutualistic, or commensalistic as American Shad and many freshwater mussels are species of conservation concern. A commensalistic or mutualistic relationship between these taxa may result in restoration activities affecting one species facilitating restoration of others.

“…Glochidia develop in the gill chambers of a mussel and are stored until the water reaches the proper temperature for gravid females to release the larval mussels (Kat 1984, Watters and O'Oee 2000, Smith 2001. Although some mussels are considered generalists in their host fish selection, others are very host-specific, obligate parasites (Yeager and Saylor 1995, Keller and Ruessler 1997, O'Oee and Watters 2000. Species that are rare and/or have never been abundant most likely have a narrower group of hosts or even a single host (Hoggarth 1992, Watters 1996, Haag and Warren 1997.…”

“…In later years, the research has shifted to threatened and endangered species so that once again E. crassidens has been overlooked (Yeager andSaylor 1995, Jones andNeves 2002). This species enjoys a widespread distribution, but is only abundant locally Mayer 1992, Williams et al 2008).…”

“…This size screen was deemed ample for capturing the larvae without capturing too much of the tank debris upon cleaning the tanks in search of juveniles (Khym and Layzer 2000 Yeager and Saylor 1995). When the screens were added to the tanks, the water flow was decreased to prevent the screens from becoming clogged with debris from the tank.…”
