Our laboratory studies of the physiological effects of zebra mussel (Dreissena polymorpha) infestation on the freshwater mussels Actinonaias ligamentina and Amblema plicata (Unionidae) show that (i) zebra mussel infestation causes stress and symptoms of starvation in unionid mussels, (ii) unionid species are affected unequally, and (iii) symptoms of starvation are greater when initial condition is low. Nutritive stress in infested unionid mussels was indicated by shifts to lower metabolic rates, more protein-based metabolism (lower O:N ratios), and compensatory increases in grazing rates. Starvation may be the result of local food depletion and (or) increased metabolic cost. Actinonaias ligamentina (subfamily Lampsilinae) was more sensitive to infestation than Amblema plicata (subfamily Ambleminae), as indicated especially by changes in oxygen uptake rate and grazing rate. The effects of infestation were greater in mussels that were already in low condition. Our results indicate that the decline in diversity of unionid mussels since the introduction of zebra mussels is due to species-specific rates of starvation.

Food Concentrations

We examined the effects of inorganic suspended sediment (0, 1, 10, and 100 mg ·L-1) and food concentrations (0.1, 0.5, and 2.0 mg particulate organic matter (POM) ·L-1) on clearance, ingestion, respiration, feces, and pseudofeces production rates and assimilation efficiencies of adult zebra mussels (Dreissena polymorpha) under laboratory conditions at 20 ± 1°C. Food quality indices (the proportion of inorganic to organic material in feeding suspensions = IO ratios) ranged from 0.304 to 63.04. Suspended inorganic sediment above 1 mg ·L-1 greatly reduced clearance rates, ingestion rates, and assimilation efficiencies of zebra mussels, and ingestion of POM was maintained only at high food concentrations. Pseudofeces were produced copiously by zebra mussels in the 100 mg ·L-1 sediment treatment, and there appeared to be an increased metabolic cost associated with pseudofeces production. Declining food quality caused exponential declines in clearance, ingestion, and absorption rates, water processing potential, and assimilation efficiencies, with the sharpest declines between IO ratios of 0.304 and 5.0. IO ratios in turbid rivers often exceed 1.71, our experimental threshold where scope for growth for zebra mussels was zero. We contend that zebra mussels in turbid rivers may exhibit low growth potential and may not stabilize at the high population densities seen in their lake counterparts.

Effective Conservation

Zebra mussels (Dreissena polymorpha) in Lake Champlain have colonized the shells of many native unionids, causing declines in their abundance. Periodically cleaning zebra mussels from unionids may be an effective conservation technique, if unionids can recover from the stress induced by zebra mussels. Efforts will need to target species that are most vulnerable to fouling and subsequent energetic losses. We used glycogen as a biochemical indicator of energetic stores to assess species-specific differences in tolerance to zebra mussels. There was no evidence that glycogen levels decreased as dreissenid/unionid mass ratios increased in Elliptio complanata. However, dreissenid/unionid mass ratios as low as 0.25 in Lampsilis radiata were correlated with a significant decline in glycogen content. The ability of these species to recover glycogen after zebra mussel removal and replacement in situ was also evaluated. Mussels were cleaned of zebra mussels and replaced in situ. After 10 weeks, cleaned, heavily fouled, and never-fouled (control) mussels were collected. Glycogen levels in fouled mussels were lower than in the control mussels, while glycogen levels in cleaned mussels did not differ from the control mussels. Results suggest that heavily fouled E. complanata and L. radiata can recover glycogen levels if cleaned of zebra mussels and that cleaning may be a viable option for unionid conservation.
