Energy from fish p**p? Reducing aquaculture waste? Meet the team making it happen. 💡🐟

Recirculating Aquaculture Systems have become popular due to their compact and manageable size, but one of the biggest challenges to RAS is waste management.

The Conservation Fund (TCF) Freshwater Institute has explored composting aquaculture waste to produce a sellable fertilizer and is currently investigating energy generation through anaerobic digestion. There are benefits and drawbacks, but it represents an exciting new frontier.

In March of 1913, a catastrophic flood on the Great Miami River swept through Southwest Ohio, leaving cities in ruins. ⛈️

Within two years of the "Great Flood of 1913," the Miami Conservancy District (MCD) was created to build dams, levees, and storage basins to control the Great Miami River and its tributaries. Citizens vowed that nothing that devastating would occur again.

They succeeded, and for decades MCD has been innovating and adapting to monitor river flow and water quality to protect Southwest Ohio residents.

Save the Sound, Remove the Dam.

In 2023, Connecticut non-profit Save the Sound worked with local partners to remove the derelict Strong Pond Dam (on the Norwalk River) in hopes of restoring the channel to a more natural state.

Above the dam were about five miles of accessible stream habitat, critical for native diadromous species like sea lamprey and river herring.

In addition to limiting fish migration, the dam also slowed down flows, which can lead to increased water temperature and declines in dissolved oxygen above and below the barrier.

Learn how the removal was pulled off, and how it's inspiring dam removals nearby ➡️ https://www.fishsens.com/removing-strong-pond-dam-and-channel-restoration-on-the-norwalk-river/

It’s difficult to encapsulate the magnitude of the Laurentian Great Lakes. As the largest lake system on Earth, it holds 84% of North America’s fresh water and creates distinct local weather patterns.

It’s unsurprising, therefore, that dozens of organizations exist to protect, monitor, and study these ecosystems. One of these is the Cooperative Institute for Great Lakes Research (CIGLR)

CIGLR operates immense forecasting models, and the datasets are extremely complicated. But they’re also crucial, and CIGLR needs people to understand them.

To bridge this gap and aid researchers using this data, the institute is turning toward a powerful but sometimes controversial tool: artificial intelligence.

The group has sponsored and overseen restoration and conservation efforts ranging from culvert removal to complete stream restoration, with over 130,000 acres in Maine’s wilderness currently under its protection.

In 2021, AMC worked with the National Park Service (NPS) and the Appalachian Trail Conservancy (ATC) to replace an undersized steel culvert on Henderson Brook—a tributary of the West Branch of the Pleasant River—that was blocking about eight miles of upstream habitat.

How does culvert removal help Maine's iconic trout and salmon? Learn more in our newest article ➡️ https://www.fishsens.com/culvert-removal-and-replica-streams-the-henderson-brook-restoration-project/

As global climatic trends shift warmer, there is growing concern around how ecosystems may change, thus highlighting the importance of climate change refugia.

For aquatic systems, refugia are often isolated, high-altitude reservoirs fed by groundwater and snowmelt, allowing them to better maintain consistent temperatures in a variable climate.

Using long-term monitoring datasets from subalpine lakes in Maine, a 2026 study linked lake elevation to changes in springtime dynamics, describing how such variations affect plankton communities, a key pillar of limnic food webs.

In 2016, fish sampling efforts in the Great Smoky Mountains National Park uncovered Smallmouth Bass with elevated mercury levels. 🐟

This discovery was particularly concerning since these streams should be relatively pristine, with no direct point source of mercury.

To understand why this happened and help anglers determine safe fishing spots, a master’s student at the University of Tennessee, Knoxville, sampled taxa from different levels of the food web in the three creeks in hopes of identifying patterns of mercury biomagnification.

Reefs aren't always made of coral. They can be composed of rocks, man-made structures, or... worms. 🪱🪸

In Texas' Baffin Bay, serpulid worms make up vital biogenic reefs. Human pressure has shrunk these rare, ancient reef systems over the past decades, but new projects aim to bring them back.

From scuba diving to water quality monitoring, it's no easy undertaking. But the team of Texas A&M Corpus Christi researchers is dedicated.

As the Chesapeake Bay faces problems like pollution and warming, natural resource managers worry about the future of iconic species like striped bass and drum, particularly how they’ll respond to a changing ecosystem. 🐟

To predict these changes, a team at NOAA’s National Centers for Coastal Ocean Science is tagging these species. A sometimes arduous task, the scientists are tapping into and expanding the Atlantic Cooperative Telemetry Network to better understand these popular sportfish.
