The pallid sturgeon has become a living symbol of the old, natural Missouri River struggling to survive in the new river we've created. This odd looking, prehistoric fish only lives in the Missouri River and the Mississippi River below St. Louis. It's uniquely adapted to the intense environment of this turbid, sandy and free-flowing river.
Channelization, loss of sediment and damming of the Missouri River have all impacted the spawning ability of the sturgeon and the survival of its young. As biologists study the habitat needs of this fish and engineers attempt to recreate this habitat on our channelized river, emergency measures have been taken to restock hatchery raised sturgeon throughout the Missouri River basin.
USFWS biologist Tracy Hill will join us for a peek into the extremely difficult process of tracking and catching breeding age sturgeon, spawning them in the hatchery and reintroducing the young fish to the wild Missouri River. It takes the cooperation of several state and federal agencies and a trial and error learning curve that continues to improve.
