The removal of a dam in the Wynants Kill, a Hudson River tributary, has restored more than a quarter mile of spawning habitat for river herring for the first time in 85 years. Approximately 1,500 dams impede the flow of tributaries and streams throughout the Hudson River watershed. One down . . .Read More
Coral may not have the capacity to adapt fast enough to our rapidly changing environment. If things continue at current rates, reef erosion will likely cause the diversity of corals to decline, leading to reduced habitat complexity and loss of biodiversity.Read More
All species and subspecies of sturgeon are imperiled worldwide due to the impacts of human activity. Here in the United States, Atlantic Sturgeon, which spawn in the Hudson River, were declared an endangered species in 2012. If the Lake Sturgeon is to avoid the same fate, further research regarding its life history and spawning habitat is essential.Read More
There was a time when every river town in the Hudson Valley was home to commercial shad fishermen. The appearance of their boats and nets on local shores was a certain sign spring had arrived. Tradition taught that the first run of American shad left the Atlantic to spawn in the river’s fresh water reaches when the forsythia were in bloom in late March – early April. Dogwoods signaled the middle of the run. The final run of shad, the largest of the fish, according to Hudson rivermen, occurred when the lilac flowered in mid-May.
In 2010, New York State halted commercial fishing of American shad because of collapsing populations in the river and on the coast. Shad spend most of their lives at sea following an isotherm of 13 to 18 degrees Celsius, moving south and north as the Atlantic waters warm and cool. They migrate up estuaries from the St. Johns in Florida to the St. John in New Brunswick and each in between. George Washington once had a commercial shad fishing operation on the Potomac.
No one reason has yet been identified for the collapse of the fishery. It is possible the blame is shared amongst many causes including: power plant cooling water intakes such as those at Indian Point; a coastal intercept fishery that captures the shad before they can migrate; and zebra mussels that rob the estuary of vital nutrients.

One objective of REON is highly accurate data gathering with minimal environmental disruption, a vision shared by a team of researchers at MIT’s Computer Science and Artificial Intelligence Laboratory who have developed a soft robotic fish they say could someday “infiltrate schools of real fish to gather detailed information about their behavior.” Click below for video and story.Read More
On Thursday, 6/12, RiverU took a tour of the local wastewater treatment plant in Beacon and Continental Organics/Aquaponics located in New Windsor. The Beacon Wastewater Treatment facility was established in 1913 and is still functioning today at the same location. Early in the morning, we toured this facility, which takes in both gray and black […]Read More
