Where Do “Hatchery Fish” Come From?

Steven Coomer and Art Broncheau of the Nez Perce Fisheries Research Facility in Kooskia Idaho gave the Montana Outdoor Radio Show an inside look at their fisheries program recently.


Art Broncheau shows smolts held inside temperature controlled trays with a continuous 5 gal/min water flow rate.



Each Tray holds 4,000 young salmon from different breeding pairs.



Water temperature is continuously monitored and adjusted to increase or slow growth rates. The warmer the water the faster the growth, but also the more chance for disease.



Once the young salmonoids are big enough they are moved outside. Here Steve feeds about 250, 000 of them, a daily routine.


Once the salmon grow big enough they are transported and released into the river and then they are on their own!

Thank you to the Nez Perce FisheriesResearch Facility for allowing MORS to visit their facility!
