USACE fishes for data to help save Green Sturgeon
U.S. Army Corps of Engineers contractor Michael Hellmair, a fisheries biologist with Fishbio, Inc., waits to measure a North American green sturgeon on the bank of the Sacramento River in Hamilton City, California, October 13, 2023. Hellmair supports the USACE Sacramento District Planning Division’s efforts to gather behavioral data through telemetric tagging of the North American green sturgeon that migrate through the river every three to five years. 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. USACE fisheries biologists have inserted telemetric tags in 85 green sturgeons over the past four years. (U.S. Army photo by Ken Wright)
