October 30, 2015 — A green sturgeon tag is a real find, for a kid on the beach and for NOAA scientists.

Ethan Mora and Liam Zarri, researchers from NOAA’s Southwest Fisheries Science Center in Santa Cruz, woke up early on a recent October morning to gather critical scientific data on green sturgeon. But they weren’t off to some remote research station; they were going to an elementary school in Napa to reward one of the students with $20 for finding a lost satellite tag.

Deja Walker, a third-grade student at Napa Valley Boys and Girls Club, was strolling with her grandparents on Stinson Beach near San Francisco in early October when she noticed some boys throwing around what looked like a toy. When the kids tossed it aside, she investigated and found the nearly foot-long tube offered a reward for its return to NOAA.

What Deja didn’t know was that she had found one of several satellite tags used by NOAA researchers to understand the impact of commercial halibut fishing on green sturgeon, one of nature’s most prehistoric fish.

Green sturgeon are bottom feeders, scavenging on invertebrates and small fish. They can grow to about eight feet in length and live for about 70 years. Although they spawn in fresh water, the adults may travel up and down the West coast from Mexico to Alaska.

Sturgeon have meandered throughout our oceans and rivers since dinosaurs roamed the Earth. But despite their long history, one population of green sturgeon in California may be edging closer towards extinction. The southern population, or those green sturgeon that spawn in the Sacramento River basin, were listed as threatened under the Endangered Species Act (ESA) in 2006 because of the loss of historical spawning habitat.
