MSU’s FishPass Project: An Innovative Solution for Protecting Local Fish and Ecosystems

The FishPass Project: A Model for Invasive Species Control and Ecosystem Restoration

On July 31, 2024, researchers at Michigan State University (2024 USNews Ranking: 60) (MSU) embarked on an unprecedented project aimed at addressing the challenge of preventing invasive fish species from entering rivers without completely blocking all fish. Commissioned by the Great Lakes Fishery Commission (GLFC), the project aims to create a selective fish barrier named FishPass in Traverse City over the next decade. This innovative barrier is designed to block invasive and parasitic sea lampreys while allowing native fish species such as lake sturgeon and pike to pass through. If successful, FishPass could serve as a global model for controlling invasive species.

The construction of the FishPass project began in May of this year, with Michigan recently allocating $1 million in its budget to support the GLFC’s efforts. This initiative represents the culmination of efforts to reconnect the Boardman/Ottaway River with Lake Michigan, following the removal of three upstream dams over the past two decades, which restored the natural flow of 160 miles of river. The sea lamprey, a parasitic fish that attaches to other fish and feeds on their bodily fluids, has significantly reduced native fish populations since its introduction through man-made waterways in the 19th century. Historically, GLFC has relied on barriers like dams to prevent sea lampreys from entering rivers, but these barriers also hinder the passage of native fish.

The design of FishPass draws inspiration from single-stream recovery, utilizing the behavioral characteristics of different fish species to separate them using obstacles and traps. The success of this project will depend on multidisciplinary collaboration, with engineers and ecologists at MSU working together to leverage the behavioral traits of sea lampreys to prevent their reproduction while allowing native fish to pass freely. The ultimate goal is to achieve fully automated selective passage, and while initial implementations may not be perfect, researchers are optimistic about future improvements.

Selective Fish Barriers and Their Impact on Local Ecosystems

The FishPass project highlights the importance of selective fish barriers in maintaining the balance of local ecosystems. Invasive species, such as the sea lamprey, pose a significant threat to native fish populations, leading to declines in biodiversity and altering the ecological dynamics of aquatic environments. The introduction of invasive species can have cascading effects on local ecosystems, as seen in various case studies across the globe.

For instance, the introduction of the Nile perch (Lates niloticus) into Lake Victoria in the 1950s aimed to boost fisheries but resulted in the near extinction of native cichlid species. This case exemplifies how invasive species can disrupt food webs and lead to the loss of biodiversity. The Nile perch thrived in the absence of natural predators, decimating the cichlid population, which had been a crucial component of the lake’s ecosystem. The economic benefits derived from the Nile perch fishery came at a significant ecological cost, underscoring the need for careful consideration of the long-term impacts of introducing non-native species.

Selective fish barriers, like the one proposed in the FishPass project, can mitigate the negative effects of invasive species while allowing native fish populations to thrive. By employing innovative engineering solutions, these barriers can be designed to accommodate the specific needs of different fish species, ensuring that local ecosystems remain balanced and resilient. The FishPass project serves as a potential blueprint for similar initiatives across the United States and beyond, demonstrating that it is possible to manage invasive species without compromising the health of native populations.

The Role of Multidisciplinary Collaboration in Environmental Projects

The success of the FishPass project is rooted in the collaborative efforts of various disciplines, including engineering, ecology, and environmental science. Multidisciplinary collaboration is essential for addressing complex environmental challenges, as it brings together diverse perspectives and expertise to develop innovative solutions.

At Michigan State University, the integration of engineering and ecological research has been pivotal in advancing projects like FishPass. Engineers and ecologists work hand-in-hand to understand the behavioral patterns of sea lampreys and native fish species, allowing them to design effective barriers that meet the needs of both groups. This collaborative approach not only enhances the project’s chances of success but also fosters a culture of innovation and problem-solving.

The importance of multidisciplinary collaboration extends beyond the FishPass project. For example, the Prairie Strip Partial Budget tool developed by MSU’s Department of Plant, Soil, and Microbial Sciences exemplifies how interdisciplinary efforts can lead to practical solutions for agricultural sustainability. By combining agricultural research with economic analysis, this tool helps farmers assess the benefits of restoring marginal lands to prairie, ultimately promoting soil health and biodiversity.

In the context of environmental projects, collaboration among researchers, policymakers, and local communities is crucial for ensuring that solutions are both effective and socially acceptable. Engaging stakeholders in the decision-making process fosters a sense of ownership and responsibility, leading to more sustainable outcomes.

Historical Impact of Invasive Species on Native Fish Populations

The historical context of invasive species provides valuable insights into the potential consequences of introducing non-native species into ecosystems. The case of the Nile perch in Lake Victoria serves as a cautionary tale, illustrating how well-intentioned interventions can lead to unintended ecological disasters.

In the 1950s, the introduction of the Nile perch was intended to enhance local fisheries and stimulate economic growth. However, the rapid proliferation of the Nile perch, coupled with the absence of natural predators, resulted in the near extinction of hundreds of native cichlid species. This drastic shift in the ecosystem not only diminished biodiversity but also disrupted the livelihoods of local fishermen who relied on cichlids as a primary source of income.

The lessons learned from the Nile perch introduction underscore the importance of conducting thorough ecological assessments before implementing species introductions. Understanding the potential impacts on native populations and the broader ecosystem is essential for making informed decisions that prioritize long-term ecological health over short-term economic gains.

In the United States, the introduction of invasive species has similarly led to significant declines in native fish populations. The sea lamprey’s invasion of the Great Lakes is a prime example, as it has caused substantial harm to local fish species, including lake trout and whitefish. The FishPass project represents a proactive approach to addressing this issue, aiming to prevent further declines in native populations while allowing for the restoration of natural ecosystems.

Innovative Engineering Solutions for Wildlife Conservation

The FishPass project exemplifies the role of innovative engineering solutions in wildlife conservation. By leveraging advanced technologies and engineering principles, researchers can develop effective strategies for managing invasive species and restoring ecosystems.

The design of selective fish barriers requires a deep understanding of fish behavior, hydrodynamics, and ecological interactions. Engineers at MSU are tasked with creating a barrier that not only prevents sea lampreys from entering the river but also allows native fish to navigate freely. This challenge necessitates a combination of engineering expertise and ecological knowledge, highlighting the importance of interdisciplinary collaboration.

Moreover, the potential for automation in the FishPass project represents a significant advancement in wildlife conservation efforts. The goal of achieving fully automated selective passage could revolutionize the way we manage invasive species, allowing for real-time monitoring and adaptive management strategies. As technology continues to evolve, the integration of artificial intelligence and machine learning into conservation practices may enhance our ability to respond to ecological challenges more effectively.

The success of the FishPass project could inspire similar initiatives across the United States, encouraging other regions to adopt innovative engineering solutions for wildlife conservation. By prioritizing the health of local ecosystems and leveraging multidisciplinary collaboration, we can work towards a more sustainable future for both native species and the communities that depend on them.
