Summary

The Minnesota Department of Natural Resources (MNDNR) has been quantitatively sampling a mussel bed in West Newton Chute (a side channel in Navigation Pool 5 of the Upper Mississippi River, UMR) annually since 2008. Briefly, ~200 systematically-placed 0.25 m2 quads are sampled annually; divers excavate substrates to a depth of ~15 cm and place material into a 6 mm mesh bag. Mussels are identified to species, aged via external annuli, measured for shell length, and sexed. From 2008-2016, this mussel bed contained 12-16 live species, had densities that ranged from 4-10/m2, and juveniles (≤ 5 years old) comprised 3-18% of the assemblage. Because this assemblage was well characterized, it represented an excellent location to estimate vital [...]

Purpose

The limited information on population vital rates (i.e., survival, growth) in freshwater mussels makes it difficult to evaluate the effects of management actions such as habitat restoration projects on native mussel assemblages. Diverse assemblages with demographically and genetically robust populations and adequate population vital rates are more likely to be sustainable, be resistant to disturbance, and provide important ecological services. Vital rates can provide a framework to evaluate management actions and can serve as inputs to population models. In particular, vital rates may help discern critical life stage bottlenecks and evaluate environmental and management scenarios.
