Fish Hatchery – Daniel, Wyoming

Hello, I’m Bret Barngrover, Superintendent
of the Daniel Fish Hatchery with the Wyoming Game and Fish Department. The Daniel Hatchery is located approximately
12 miles north of Pinedale, Wyoming. Today I’ll be showing you guys around the
hatchery, the fish we raise, and the technology we use to raise those fish, so follow me and
we’ll show you around our facility. Hello and welcome to the Daniel Hatchery. When you walk into the entrance the first
thing you’ll come to is our visitor center. Here we have some historical photos and historical
fish culture tools that we used. We also have a visitor login. Please, at the end of your visit stop in,
sign, leave a few comments on your thoughts about your visit. So, follow me and we will head into the hatchery. As you enter the hatchery please keep in mind
we have strict biosecurity measures in effect. We have floor mats that disinfect shoes. Please utilize those before entering the hatchery. So here in the hatchery this is where our
fish begin. We receive eyed-eggs from other facilities
or from our own Colorado River brood stock. These eggs are shipped to us at various times
of the year. They’re hatched out in the hatchery building. We’ll raise them up to about 2 inches in length
before we move them outside when they require more room to grow. Below in front of us, we have golden trout
sac fry. these golden trout came from our Story Hatchery. We’ve had them for about 3 weeks right now. We will hang on to these fish until August
of 2019 when they’ll be stocked out via helicopter into the high mountain lakes of Wyoming. So here at the Daniel Hatchery, we raise a
wide variety of salmonids for the public to catch. We raise brook trout, brown trout, splake,
lake trout, tiger trout, kokanee salmon, golden trout, and our own native Colorado River Cutthroat
Trout, so follow me outside. We’ll take a look at our Colorado River Cutthroat
broodstock that we have. So here beside me are some of the Colorado
River broodstock that we manage at the Daniel Hatchery. The Daniel Hatchery was chosen to house this
broodstock based on our location within the fishes native drainage here in Wyoming. We manage five different year classes with
this broodstock as these fish only mature when they’re four years old. So we’ll collect eggs when they’re four and
five and then we’ll stock our brood culls out into local community fishing ponds. The eggs and the fish raised from the eggs
that we collect are mainly used for conservation and restoration efforts within the native
drainage, but we also ship some of the eggs to other hatcheries within Wyoming and they
raise them up to support local fishing opportunities in their communities. So behind me you’ll notice the rest of our
concrete rearing units. These concrete raceways they’re used mainly
for production and they support in large part our golden trout program. Annually Daniel raises 40 thousand to 60 thousand
golden trout to be stocked in the high mountain lakes of Wyoming, but we also use some of
these raceways for our other species that we raise; the brown trout, the kokanee, and
then also our Colorado River Cutthroat trout. Daniel raises anywhere between 250-300 thousand
fish every year to be stocked out within Wyoming’s waters. If you follow me we’ll go outside and look
at some of our water conditioning equipment. This equipment is used to degas and oxygenate
the water to provide optimal rearing conditions for the fish we raise. Alright, so we’re now standing outside the
newly constructed water treatment facility at the Daniel Fish Hatchery. This building and equipment inside was completed
in the fall of 2018. Inside we have two oxygen generators, a filter
UV system, and then a vacuum degasser. As we go into the building the first things
you’ll see are our oxygen generators. They produce quite a bit of noise so we’ll
walk right past them and into our RFUV and pump building that we have there. So these RFUVs, or rotofilter UV system, is
the first step in our water treatment. The water flows from our spring line directly
into these two units. We have two units for backup reasons in case
one fails the other one will still operate and safeguard the facility. How these RFUVs work, the water comes in from
the side, flows into the drum filter and then flows out through the micro screen. From there it flows through a series of UV
lights and then into our big pump chamber that pumps water to the vacuum degasser. As these RFUVs work and the filters get clogged
up, we have internal floats that will trigger a backwash and it’ll remove any solids that
have accumulated on the filters. So from, so after the water has gone through
the UV filters we have a series of UV lights that the water passes through. Once it passes through the UV lights, it flows
into a pump chamber, which is right over here and then it is pumped through the vacuum degasser. We’ll go outside now and look at that vacuum
degasser. So the vacuum degasser allows us to do a couple
different things. One, it removes all the nitrogen gas that’s
in the water, which is harmful to the fish, and then also in the bottom of the vacuum
degasser you’ll see the copper line, we’re able to add oxygen back into the water from
our oxygen generators that we saw earlier. This step allows us to saturate the water
to 100 percent with oxygen providing a nice clean healthy environment for rearing. So that concludes the tour of the Daniel Fish
Hatchery. Thanks for joining us today. If you get a chance, please stop by. We’re open 7 days a week 8am to 5pm. When you stop by, be sure to bring your fishing
rods as we have 40 rod creek right behind us and it provides excellent brown trout and
rainbow trout fishing year round. Again, thanks for joining us and we look forward
to your visit.

  1. That was a fascinating tour.  Thanks WGFD!   A follow-up video on your time-travel technology would also be appreciated.  Viewing the hatchery tour in August 2018 (summer),  I was shown a water treatment facility that was completed in the fall of 2018.  WGFD is definitely ahead of the science and technology curve.

  2. Great video! I used to rear rainbows in Colorado, the regulations became too much for the little guy. I do appreciate the technology though!

  3. I want to start trout fish hatchery in my country. can someone give me some details information about this business.? like how much space is needed, how much minimum investment will be required, which weather condition is best for trout fish. and how much experience is needed to start this business? i have no experience at all just got some information on youtube. please need your kind suggestions. thanks
