“…This could be especially useful in systems where mussels reach maturity within a couple of months and reproduce for many months throughout the year, as occurs in the warm, productive reservoirs in the Southwestern U.S. (e.g., Gerstenberger et al 2011;Culver et al 2015). In such systems, mussels would need to be physically removed approximately every six to eight weeks for several months to prevent maturation and reproduction.…”

“…Our deployment schedules and operations differed for each experiment. We deployed the pens at a time and water depth that coincided with expected mussel recruitment for each waterbody (Culver et al 2015; C. Karp, U. S. Bureau of Reclamation and D. Daft, personal observations) and the optimum feeding strategy (pelagic or benthic) of the candidate control agent. The Bluegill pens were deployed in mid-December 2012, suspended from a surface longline to a water depth of 6 m (Figure 1C).…”

“…Control and treatment pens were alternated every 8 m to minimize the potential effect of adjacent pens. The bottom of each pen was above the observed thermocline and hypolimnion, below which mussels cannot survive (Culver et al 2015). Two experimental substrates were attached to the longline at a similar depth as the experimental pens to monitor mussel settlement weekly without disturbing the pens.…”

“…For example, penning Bluegill under or around mussel-infested infrastructure (water towers, floating restrooms, pump barges, and docks) would likely eliminate the need to clean the structures frequently during periods of high mussel recruitment-a costly, labor-intensive tactic. This could be especially useful in systems where mussels reach maturity within a couple of months and reproduce for many months throughout the year, as occurs in the warm, productive reservoirs of the southwestern USA (e.g., Gerstenberger et al 2011;Culver et al 2015). In such systems, mussels would have to be physically removed approximately every 6-8 weeks for several months to prevent maturation and reproduction.…”

The quagga mussel, Dreissena bugensis, is a harmful aquatic pest that invaded the Southwestern United States in 2007. Challenges with managing this pest have been encountered because the invaded systems are primarily open water sources used for human consumption and/or are connected to freshwater habitats containing threatened and endangered species. Existing chemical and physical control methods are undesirable, with use of some methods restricted or prohibited, because they pose risks to humans and ecosystems more broadly. To address this problem, we investigated the efficacy of using resident fishes as biocontrol agents for managing different life stages of quagga mussels on different spatial scales in a site-specific manner. We conducted field experiments to test whether planktivorous Bluegill, Lepomis macrochirus, reduced mussel infestations on substrates of varying orientations in small and large pens through predation on larval mussels. We also conducted an experiment to evaluate whether the carnivorous Redear Sunfish, Lepomis microlophus, reduced mussel infestations established on substrates of varying orientations in small pens through predation on juvenile and adult mussels. Bluegills significantly reduced mussel infestations on all substrates in the pens through predation on larvae and small, juvenile mussels. Redear Sunfishes reduced existing juvenile and adult mussel populations in some cases, with consumption varying among individuals and substrate orientation. Our results indicate that fishes, specifically Bluegill, may represent effective site-specific biocontrol agents for quagga mussels, reducing impacts on targeted infrastructure (e.g., water towers, docks, pipes) and habitats having different surface orientations by controlling more than one life stage of the pest. Development of an integrated pest management strategy, that considers application of this tactic in combination with others, would undoubtedly improve management of quagga mussels, and potentially congeneric zebra mussels, within lake and reservoir ecosystems.

Biological invasions are increasing in frequency and the need to mitigate or control their effects is a major challenge to natural resource managers. Failure to control invasive species has been attributed to inadequate policies, resources or scientific knowledge. Often, natural resource managers with limited funds are tasked with the development of an invasive species control program without access to key decision-support information such as whether or not an invasive species will cause damage, and what the extent of that damage may be. Once damages are realized, knowing where to allocate resources and target control efforts is not straightforward. Here we present the history of invasive species policy development and management in a large, multi-jurisdictional and multi-use aquatic ecosystem. We present a science-based decision-support tool for on-the-ground aquatic invasive species (AIS) control to support the development of a sustainable control program. Lastly, we provide a set of recommendations for managers desiring to make an AIS control implementation plan based upon our development of novel invasive species research, policy and management in Lake Tahoe (USA). We find that a sustainable invasive species control program is possible when science, coordination and outreach are integrated.
