USACE fishes for data to help save Green Sturgeon
U.S. Army Corps of Engineers Sacramento District senior fisheries biologist Robert Chase instructs Lt. Col. Dianna Lively, the district’s deputy commander, on how to log biometric data on North American green sturgeon during a telemetric tagging expedition on the Sacramento River in Hamilton City, California, October 13, 2023. USACE fisheries biologists have inserted telemetric tags in 85 green sturgeons over the past four years, which is helping them gather behavioral data on the ancient fish species. The data is then analyzed to determine the degree of impacts USACE civil works projects may or may not have on the species that since 2006 has been listed as threatened under the Endangered Species Act. Lively caught three sturgeons during the trip which cumulatively measured nearly 19 feet long. The largest measured nearly seven feet long. (U.S. Army photo by Ken Wright)
