“…It may be possible that infestations at high concentrations can have a negative impact on glochidia attachment rates to fish gills. Over infestation has been known to cause increased stress, gill damage, decreased weight, negative influences on critical swimming speeds and mortality of fish (Dodd et al ., ; Kaiser, ; Howerth & Keller, ; Crane et al ., ; Taeubert & Geist, ). The increased infestation intensities may have masked any patterns expected to see with fish and freshwater mussel combinations; therefore, it is important when doing future studies to account for concentrations of glochidia throughout the stages of experiment as we demonstrated in these experiments.…”

“…Infestation intensities were determined by the total juveniles and glochidia that had attached to each fish (Crane et al ., ). Host fish experiments were analysed using univariate statistics; a two‐way ANOVA was used to determine the relationships between percent transformation [juveniles/(glochidia attached + juveniles)] for each fish and mussel pairing to determine any relationships.…”

Summary Freshwater mussel populations have declined, in part, from changes in host communities. However, it is unknown if fish from adjacent catchments could be used to augment mussel populations in the Great Lakes inland rivers, and if so, whether this association would be impacted by known genetic structure in mussels and fish. This study tested how host fish origin (i.e. catchment) impacts the transformation of the endangered unionid Epioblasma triquetra from larval into juvenile life stages while concurrently considering potentially genetically distinct populations of mussels and hosts. We quantitatively determined if Percina caprodes and Percina maculata from the Lake Michigan, Erie and Huron basins are laboratory‐successful hosts for E. triquetra. Experiments were performed in autumn and spring to document any seasonal effects on transformation. Percina caprodes was reconfirmed to be a successful host for E. triquetra, and for the first time, P. maculata was also determined to be a successful host in the Great Lakes region. Results suggest no differences in juvenile transformation with allopatric and sympatric fish and mussel pairings based on Great Lakes basin origin; therefore, transformation success may not parallel differences in genetic structure. In addition, results suggest seasonal differences in the developmental stages of E. triquetra juveniles. Knowing the most efficient strategy to optimise juvenile transformations can make reintroductions, augmentation and overall conservation efforts of E. triquetra successful. These data will help in developing recovery strategies for E. triquetra in the Laurentian Great Lakes by understanding variation in host use and nuances in this host–parasite relationship.

“…A variety of aquatic parasites, such as the larvae (glochidia) of many species of unionoid mussels, attaches and encysts on the gills of fish (Crane et al 2011; Denic et al 2015; Meyers et al 1980; Young and Williams 1984). Such encystment can affect both the physiology and behaviour of the host.…”

Encystment of parasitic freshwater pearl mussel (Margaritifera margaritifera) larvae coincides with increased metabolic rate and haematocrit in juvenile brown trout (Salmo trutta)

Gill parasites on fish are likely to negatively influence their host by inhibiting respiration, oxygen transport capacity and overall fitness. The glochidia larvae of the endangered freshwater pearl mussel (FPM, Margaritifera margaritifera (Linnaeus, 1758)) are obligate parasites on the gills of juvenile salmonid fish. We investigated the effects of FPM glochidia encystment on the metabolism and haematology of brown trout (Salmo trutta Linnaeus, 1758). Specifically, we measured whole-animal oxygen uptake rates at rest and following an exhaustive exercise protocol using intermittent flow-through respirometry, as well as haematocrit, in infested and uninfested trout. Glochidia encystment significantly affected whole-animal metabolic rate, as infested trout exhibited higher standard and maximum metabolic rates. Furthermore, glochidia-infested trout also had elevated levels of haematocrit. The combination of an increased metabolism and haematocrit in infested fish indicates that glochidia encystment has a physiological effect on the trout, perhaps as a compensatory response to the potential respiratory stress caused by the glochidia. When relating glochidia load to metabolism and haematocrit, fish with low numbers of encysted glochidia were the ones with particularly elevated metabolism and haematocrit. Standard metabolic rate decreased with substantial glochidia loads towards levels similar to those of uninfested fish. This suggests that initial effects visible at low levels of encystment may be countered by additional physiological effects at high loads, e.g. potential changes in energy utilization, and also that high numbers of glochidia may restrict oxygen uptake by the gills.

“…In rainbow darters ( Etheostoma caeruleum ), encystment on the gills by glochidia of other unionid mussels has been shown to reduce foraging activity and antipredator behaviour (Crane et al. ), whereas in European chub ( Squalius cephalus ), encystment by duck mussel ( Anodonta anatina ) glochidia reduced swimming activity in the laboratory as well as dispersal tendency in the wild (Horký et al. ).…”

Do individual Activity Patterns of Brown Trout (Salmo trutta) alter the Exposure to Parasitic Freshwater Pearl Mussel (Margaritifera margaritifera) Larvae?

The hypothesis that interindividual differences in the activity of brown trout alter the exposure to parasitic freshwater pearl mussel glochidia was tested in a Swedish stream. Wild yearling brown trout (N = 103) were caught, individually tagged for identification and scored for open‐field activity during standardized laboratory tests in June. Fifty gravid freshwater pearl mussels were relocated to the stream, where after the trout were released back into the stream. The fish were recaptured in October (N = 35), checked for glochidia encystment (infested individuals: n = 6) and re‐scored for open‐field activity traits. Swimming velocity during the test was higher in fish infected with glochidia, suggesting that high activity could increase their exposure to glochidia. Potentially, as metabolism rate and ventilation rate typically increase with activity, elevated activity may lead to an increased likelihood of glochidia passing over the gills. This novel finding suggests that glochidia infestation is non‐random and that the behaviour of the host fish can influence the likelihood of glochidia infestation.
