Evaluating the Effectiveness of Freshwater Mussel Mitigation Strategies

Relocation of mussels is applied as a mitigation strategy for potential impacts on threatened mussel species resulting from bridge construction or repairs. Demonstrably efficient surveys are required to document the distribution and abundance of mussels within the potentially impacted area to enable relocation. Captive propagation of juvenile mussels could be an alternative mitigation strategy, with large numbers of juvenile mussels being released to augment populations. The research team will work in a collaborative effort among mussel experts, geneticists, and engineers to test currently applied relocation methods for mitigation, examine alternative options to provide the best ecological management approach, and test the capacity of captive propagation for population augmentation as an alternative mitigation strategy to relocation.
