Biologists were able to document the spawning of female pallid sturgeon code 30 as she released during a recapture event in the Yellowstone River near Fairview, MT.

Biologists prepare to perform ultrasound and an egg biopsy on female pallid sturgeon, radio code 30, to determine how close to spawning she is or whether spawning may already have occurred.  Biologists from Montana Fish, Wildlife and Parks determined that code 30 eventually spawned in the Yellowstone River on July 19-20, 2012.

Eelgrass beds such as this one found on Bainbridge Island, WA have been identified as a possible primary source of energy to the food chain and may also serve as nursery areas for juvenile forage fish.
