Green sturgeon receives 'threatened' status

The living fossil that still patrols the rivers of the Pacific Coast recently received a boost from the US government, which listed the green sturgeon as "threatened" under the Endangered Species Act, effective April 6th. While the ruling is needed to improve the health and outlook for the species, the new listing--authorized by a final ruling by the National Marine Fisheries Service--only applies to the southern population, and may fail to protect these fish leaving California's Sacramento River System unless stiff measures are applied over a wide geographical range, said the Wildlife Conservation Society (WCS).

"We support the 'threatened' listing of green sturgeon under the ESA; it is based on good science and we feel that this is a step in the right direction," said WCS researcher Dan Erickson, one of the leading experts on the species. "However, managers will have to craft regulations carefully to protect this southern population of green sturgeon, which are highly migratory and thus vulnerable to threats in Oregon and Washington coastal waters, and even impacts in Canada."

Although the northern population of green sturgeon, which spawns in the Klamath River in California and the Rogue River in Oregon, is genetically distinct from this southern population that is now listed as Threatened, individual fish from each separate population most likely frequent the same coastal waters. According to archival-tagging studies conducted by Erickson, green sturgeon travel great distances from their ancestral rivers; individual fish from Oregon's Rogue River were tracked as far north as northern Vancouver Island, Canada, providing support to the theory that both populations likely interact with one another. Understanding the behavior and migratory patterns of these two populations are therefore important considerations for improving current regulatory frameworks for the species.

"We're hoping that additional findings on how the two populations mo
