3 July 2020. Atlantic sturgeon (Acipenser oxyrinchus) is an endangered, long-lived, anadromous fish that is found along the North American coast from the St. Lawrence River (Canada) to the St. John’s River (Florida). Historically, Atlantic sturgeon spawned in the Connecticut River, but until recently spawning populations were thought to be extirpated. In June 2020, a small, very young and therefore likely pre-migratory specimen (253mm) was captured by CTDEEP in the Connecticut River (above). This discovery is only the second after the first occurrence of small sturgeon in 2014! Together, this may be the beginning of a small Atlantic Sturgeon population rediscovering their long-lost spawning ground in the Connecticut River. CTDEEP and the Baumann Lab are working to find more fish of this size- and year class, and answer related questions about surgeon age and size and migration patterns. (CT SeaGrant project)
