“…Although glochidia of most unionid mussels can readily attach to the tissue and gill filaments of various fish species (Strayer et al 2004), metamorphosis and full larval development is normally only possible on a few host species (Dodd et al 2006). In the case of Margaritifera margaritifera, each female can release between 1 million and 4 million glochidia, which drift downstream and die within 24 to 48 h if they cannot attach to a suitable fish host (Hastie & Young 2003b), although in some cases they can remain infective for up to 6 d (Ziuganov et al 1994, Skinner et al 2003.…”

“…Several factors are critical for their survival and growth, including substrate type, silt content, water quality and an adequate supply of nutrients (Skinner et al 2003, Geist et al 2006. Barnhart (2006) found that occasional handling improved juvenile survival in North American freshwater mussels, possibly due to the removal of silt and debris. Predation and competition by microfauna may also play an important role in early juvenile mortality (Zimmerman et al 2003).…”

“…Survival of juvenile mussels reared by this method appeared to have been high during the first few months post-excystment (Taylor 2007), but this was followed by high mortalities during the second year. As with other rearing systems, little is known about causes of juvenile mussel mortality in captivity, although predation by flatworms, mechanical damage and silting up are thought to be important at the post-parasitic stage (Zimmerman et al 2003, Barnhart 2006.…”

“…Recirculation systems offer greater control over environmental variables than typical flow-through facilities, and these have been tried successfully for culturing various species of freshwater mussels in North America (Jones & Neves 2002, Jones et al 2004, 2005, Barnhart 2006), but not yet in Margaritifera margaritifera. Mussel recirculating systems typically consist of nested chambers with a downwelling flow at a rate of ca.…”

“…The accelerated decline of many freshwater mussels has recently prompted a flurry of initiatives designed to propagate and restore the species in Europe (Buddensiek 1995, Beasley & Roberts 1999, Hastie & Young 2003a, Preston et al 2007) and elsewhere (Strayer et al 2004, Barnhart 2006. In the UK, unprecedented steps have recently been taken to safeguard entire Margaritifera margaritifera (L.) populations by collecting adults from the wild and bringing them into captivity in the hope of establishing living gene banks and aiding the recovery of self-sustaining populations (Taylor 2007).…”

Freshwater pearl mussels (Unionidae: Bivalvia) rank among the most endangered aquatic invertebrates, and this has recently prompted a number of initiatives designed to propagate the species through captive breeding. Yet there are few guidelines to aid in freshwater mussel culture for conservation, and few or no results on the fate of released juveniles. We reviewed various ex situ strategies for freshwater mussel conservation with emphasis on the freshwater pearl mussel Margaritifera margaritifera (L.), one of the most critically endangered unionids. Captive breeding could help safeguard critically endangered populations, but current rearing methods need to be optimised. Areas in particular need of research include the collection and storage of viable glochidia, the development of efficient rearing systems, and the formulation of algal diets. Likewise, the degree of host specificity warrants further investigation, as this will largely dictate the success of reintroduction programmes. Finally, we note that more information is needed on the degree of genetic structuring and post-release survival before translocation programmes can be recommended. As with other conservation projects, captive breeding of the freshwater pearl mussel cannot compensate for loss of critical habitats and is likely to be most efficient in combination with in situ conservation, not in isolation.

Invasive Chinese pond mussel Sinanodonta woodiana threatens native mussel reproduction by inducing cross‐resistance of host fish

The effects of invasive alien species (IAS) on host–affiliate relationships are often subtle and remain unnoticed or insufficiently quantified. The global decline of freshwater unionid mussel species has been attributed to many causes, but little is known about the interactions of IAS, with their complex life cycle, which includes an obligatory parasitic stage (the glochidium) that develops on fishes. The capacity of a European freshwater mussel, Anodonta anatina, to develop on its widespread fish host, Squalius cephalus was tested experimentally, after previous infestations by the IAS, Sinanodonta (Anodonta) woodiana. The initial attachment of glochidia, the length of the parasitic period, and the metamorphosis success rate of A. anatina glochidia were compared among treatments of different priming infestation intensities. The metamorphosis success rate of the native A. anatina glochidia was strongly reduced (Wilcoxon Signed‐Rank Test, P < 0.001) and declined by 42.1 and 45.4% on fish hosts that were previously exposed to S. woodiana by single and multiple priming infestations, respectively, in comparison with the control group. Such cross‐resistance is expected to decrease significantly the quality of the host resources available to native mussels. This study provides the first evidence of the host‐mediated adverse impact of invasive S. woodiana on native mussel species. These results also highlight the importance of potential competition for hosts between threatened groups of affiliate species and their invasive counterparts, which should be reflected in conservation strategies.

The Texas fatmucket, Lampsilis bracteata, is a unionid mussel endemic to the Colorado and upper Guadalupe River basins of Central Texas and a candidate for federal listing under the Endangered Species Act. There is increased interest in propagation and population restoration of threatened mussels in Texas as a potential conservation method, but still little is known about their life histories and how local populations may differ in aspects of their reproductive ecology, e.g. timing of brooding and potential local adaptations to host fish. The purpose of this study was to compare host fish compatibilities and seasonality of reproduction between two populations: (a) by cross‐infesting fish from the San Saba and Llano Rivers in the Colorado River basin with sympatric and allopatric mussel larvae in the laboratory (hatchery‐produced Guadalupe bass and largemouth bass were also infested); and (b) by assessing gamete concentration, brooding period, viability of larvae and sex ratios using monthly sampling events between February 2017 and February 2018. Reproduction varied with season and between populations. The proportion of females brooding tended to be lower in the summer and the autumn, and higher during winter and spring months before peak water temperatures were reached. The sex ratio in both populations did not significantly differ from 1:1. Fecundity and larvae viability were higher in the Llano River population compared with the San Saba population. Trematode flatworms were found in several female gonad samples from the San Saba population and in a few samples from the Llano population. The highest metamorphosis success occurred on wild green sunfish and largemouth bass, and hatchery‐produced largemouth and Guadalupe bass. The average metamorphosis success tended to be higher for some mussel–fish pairings originating from the same tributary, suggesting that mussels may be locally adapted to host fish, which should be considered in conservation efforts.
