Summary:
– Tennessee Aquarium scientists are studying how culverts installed under roads affect fish movement in streams on Walden Ridge near Chattanooga.
– The project involves collecting and marking fish using minimally invasive ultraviolet-reactive tattoo “tags”.”– The aim is to understand if some culverts limit free movement and design better replacements to enable fish to navigate their territory without issue.
Have you ever stopped to think about how something as seemingly insignificant as a tiny gap between a metal cultrench and the surface of a stream can affect the lives of aquatic creatures? At the Tennessee Aquarium, scientists are dedicated to unraveling the mysteries of fish movement through streams, particularly how culverts installed under roads can hinder or facilitate their natural navigation. Their ongoing project involves cutting-edge techniques like minimally invasive ultraviolet-reactive tattoo “tags” to track and study the movement of fish in streams on Walden Ridge near Chattanooga. Join me on this fascinating journey as we explore the importance of cutting their challenges to fish and the potential solutions that could help these aquatic creatures traverse their territories freely.
Streams are the lifeblood of freshwater ecosystems, providing essential habitats for various species, including fish. Naturally, the ability of fish to move freely within their stream systems is crucial for their survival and other overall ecosystem health. However, human activities, like load construction, often present barriers to fish migration. This is where culverts come into play. Culverts allow water to pass under a road when it intersects with a stream or drainage ditch. While they are important in facilitating water flow, they can inadvertently impede fish movement if not properly designed.
Imagine being a small minnow, trying to traverse a stream and encountering a culvert. To you, it may as well be an insurmountable obstacle. Culverts can be dark, narrow, and challenging for fish to navigate. In some cases, culverts can also create strong currents or turbulence, making it even more difficult for fish to swim through. This can result in fish becoming trapped in isolated sections of the stream, limiting their access to necessary resources and potentially leading to population declines.
To address these concerns, the Tennessee Aquarium scientists have embarked on a mission to better understand how culverts impact fish movement. Using minimally invasive ultraviolet-reactive tattoo “tags,” they can track individual fish and record their movements within the stream. These tags are virtually invisible to the naked eye but glow under ultraviolet light, allowing scientists to identify and study a broad range of species without causing harm to the fish. This innovative approach enables researchers to collect valuable data on fish behavior and assess how different culverts affect their ability to navigate through streams.
The findings from this ongoing project can potentially revolutionize culvert design and enhance fish passage in streams. By studying which culvert designs pose the greatest challenges for fish, scientists can inform the development of more fish-friendly structures. This research is especially crucial for imperiled species that depend on uninterrupted movement within their habitats, ensuring long-term survival.
So, what does the future hold for fish and their journey through culverts? The Tennessee Aquarium scientists envision a world where these structures become fish “highways,” allowing aquatic life to seamlessly travel throughout their territories. The replacement culverts designed based on this research aim to reduce turbulence and provide ample space for fish to swim through. Imagine a system that considers the transportation needs of humans and the well-being of the wildlife that shares these environments.
Witnessing how conservation science and technological advancements are coming together to address these complex challenges is truly inspiring. By studying the intricate movements of fish in streams, scientists are unlocking vital information that can guide the protection and restoration of aquatic ecosystems worldwide. Through their work, we gain a deeper appreciation for the delicate balance between human infrastructure and the natural world.
As you ponder the tiny gap between the cultrench and the surface of a stream, remember that to a minnow, that seemingly inconsequential space is a world of difference. By continuing to study and understand the barriers that impede fish movement, we can strive towards a future where fish can travel dreams without limitation. Together, let’s celebrate the dedication of scientists, the wonders of nature, and the incredible potential for harmonious coexistence between humans and wildlife.
Join the Tennessee Aquarium scientists on their exciting journey as they work to unravel the secrets of fish movement through streams. Let’s ensure a brighter future for these incredible aquatic creatures and the ecosystems they call home.

To people, the tiny gap between a metal cultrench and the surface of a stream might seem inconsequential, but to a tiny minnow, it may be an impossible obstacle. Tennessee Aquarium scientists are collecting and marking fish using minimally invasive ultraviolet-reactive tattoo “tags” to study how culverts installed under roads affect how animals, including some imperiled species, can navigate through streams on Walden Ridge near Chattanooga.
This ongoing project will help us better understand if and how some culverts limit free movement and how better-designed replacements will, hopefully, allow fish to move throughout their territory without issue.
