Adults live in salt water and enter freshwater rivers during April-June (in the Hudson River) to spawn. They have also been frequently spotted opportunistically foraging and transiting in the St. George, Medomak, Damariscotta, Sheepscot, Saco, Deerfield, East, and Susquehanna rivers. Females return closer to age 20. Sturgeon eggs (a prime source of caviar) and meat (tasty when smoked) make these fish commercially valuable. Young fish reside in river systems for 2 to 7 years before migrating to the ocean. In collaboration with other researchers, we used side-scan sonar and acoustic telemetry to estimate the spawning run of Atlantic sturgeon (leaves DEC's website). DEC's Hudson River Fisheries Unit takes the lead on this work, conducting annual studies of juvenile and adult sturgeon populations in the estuary. A Day of Fishing. This smaller fish (up to four feet long), seldom travels beyond the estuary. long-distance migrations, spawning periodicity). In New York, Atlantic sturgeon are generally found in the deeper portions of the Hudson River. Atlantic sturgeon can be struck by the blades of a propeller as a boat is passing, or struck by the boat itself. That equals the weight of 15 fourth graders! In 2006, the DEC and Hudson River Estuary Program began using the developed sampling program. Atlantic sturgeon in the Hudson River. On rare occassions, they have been seen in the Narraguagus, Presumpscot, Westfield, Housatoni… With fishery-dependent data no longer available to inform stock management, fishery-independent surveys have become vital to monitor population trends to evaluate the effectiveness of the moratorium and to identify recovery goals. These trends suggest the Hudson River stock may be recovering in response to the moratorium. Paul Gallay is president of Riverkeeper. Prior to 1900, Atlantic sturgeon were abundant in the Hudson River estuary, … The Atlantic Sturgeon of the Hudson River The Atlantic sturgeon is the largest fish in the Hudson River. Atlantic sturgeon had a welcome burst of attention this month as we await their annual migration into the Hudson. In 2012, members of the state DEC captured and tagged endangered Atlantic sturgeon. Atlantic sturgeon ( Acipenser oxyrinchus) is one of the largest and longest-lived anadromous fish in North America. We are also using new and existing data from acoustically tagged adult Atlantic sturgeon to develop new, innovative data techniques to quantify and understand movement of tagged fish within the Hudson River. The Atlantic sturgeon, prized for its caviar-making roe and drastically overfished in the Hudson River, is making a comeback. Young fish may stay in the Hudson up to eight years before going to sea, where they wander in and out of rivers north to Canada and south to Georgia. It highlights the estuary's critical role as habitat for valuable fish and wildlife and the need to be vigilant in protecting this natural heritage. The average catch rate in recent years is two times higher than that observed during the start of the survey when the effects of the moratorium would not yet be fully realized due to the long maturation schedule of sturgeon. The moratorium will offer protection until these youngsters mature and launch a third generation 20 years from now. Sturgeon have been known to leap from the water on occasion, he said, “but it’s not like spotting the humpback whale that was in the lower Hudson a few years ago. The Atlantic sturgeon is one of two subspecies of A. oxyrinchus, the other being the Gulf sturgeon ( A. o. desotoi ). Benthic habitat maps developed for the Hudson River will be used to quantify and predict habitat use. In 2008, more adult males began to appear in the Hudson, likely born in 1996. Atlantic Sturgeon in the Hudson River Region Long-Term Monitoring Programs Overfishing, bycatch, and habitat loss and alteration during the late 19th century to the end of the 20th century caused significant declines in Atlantic Sturgeon stock abundances along the Atlantic coast. Scientists wanted to learn whether hatchery fishes would return back to their home river as adults to spawn, just like other wild Atlantic sturgeon. Adults are often five to eight feet long. The Hudson River estuary is an essential element in the life cycle of the Atlantic sturgeon (Acipenser oxyrhynchus) (Figure 1) and the shortnose sturgeon (Acipenser brevirostrum) (Figure 2). While they prefer deep water, sturgeon occasionally bask at the surface and leap into the air. Atlantic sturgeon spend most of their lives in ocean waters near estuaries.

In the Hudson, adults can weigh 200 pounds and grow to 6 to 8 feet in length. Population Status. Our estimate suggests that the Hudson River holds one of the largest contemporary populations of Atlantic sturgeon, yet the population remains severely depleted relative to virgin conditions. In 2003-2005, the NYSDEC and USFWS developed a survey to monitor the abundance of juvenile Atlantic sturgeon the Hudson River. The main range of the Atlantic sturgeon is in eastern North America, extending from New Brunswick, Canada, to the eastern … The Atlantic Cooperative Telemetry Network, estimate the spawning run of Atlantic sturgeon, The Atlantic Coast Cooperative Network webpage, Research Gate: Paper about pop-up satellite tags. Sort Map. To learn more, visit the Unit's migratory fish research web page. To learn more about their population trends and long-term monitoring, visit DEC's webpage about Atlantic sturgeon. Since 4,900 of these were stocked hatchery-raised fish, about 4,600 fish were thought to be of wild origin. Report sightings of live or dead sturgeon to NYSDEC by calling 845-256-3073 in the Hudson River, 631-444-0444 in marine waters or by emailing us.This data will help us better understand the occurrence of Atlantic Sturgeon in New York's waters.
