"The Maritimes population of Atlantic Sturgeon has a single known spawning site in the lower Saint John River, New Brunswick. We used acoustic tracking data from 33 tagged individuals between 2013 and 2020 to estimate spawning periodicity, survival, and potential exposure of sturgeon to the commercial fishery during their breeding season. Spawning periodicity varied from one to four years for males, and one to six years for females, on the assumption that all acoustically-tagged adult fish re-entered the Saint John River for no other purpose than to spawn"--Abstract, page iv.
