Pump failure at hatchery kills 458,000 coho yearlings

The Department of Natural Resources lost almost half of this year's coho salmon production last weekend because of a pump failure at the Platte River Fish hatchery near Beulah.
The 458,000 coho yearlings, which would have been stocked within a month, died when a pump that recirculates the water in the raceways continued to run but quit pumping water. Because the pump's motor was running, it failed to trigger the alarm that would have alerted DNR personnel at their homes.

Let's hope that the survivors can run the gauntlet of GL predators and survive to run in '06!

Maybe we could get one of those pumps for the Chicago Sanitary and Ship Canal--might take care of the carp problem!

Those will be 2005 spawners. Cohos make up a big part of the fishery in the Grand River. Looks like not for the fall of 05 though. Hopefully they can get all the bugs out of the system and get that Coho production to maximum output. The kings seem to get all the attention but cohos are fun too :)

Seems like to me they could have a spring water system feeding these raceways with fresh water insted of pumping water out of the ground wich is probaly lowering the aquafier in that region.Maybe at least certain times of the year when the water is cold river water could be deverted to deliver water to this hatchery.Just think of the amount of electricity and cost of maintaining this facility could be saved.Probaly enough cash to rear even more fish than what this facilty is already producing.Many hatcheries in the state of michigan water supplys are provided by electric pumps insted of natural ocurring underground springs wich maintain a constant year round water supply thats of a constant cold tempature:rolleyes:

Your kinda right Stinger63 but they would then need some way to keep the water at the right temperature they would then need heaters for water then try to control it's temperature to the ever changing water temperature I don/t think it could be done?????

There is a lot more to a hatchery, especially a cold water species hatchery, than you might think. There aren't many springs anywhere that could supply the volume of water required for an operation the size of the Platte River hatchery. The source of water for this hatchery is primarily Brundage creek suplimented , I believe, by ground water,as necessary
The Platte River State Fish Hatchery has a self guided tour that is very educational. Right now, part of the system is off limits to the public, due to the construction of the upgrade, I think the whole thing should be open by the time weather gets nice. If you are ever up in this area, you really should look it over. It's very educational, as well as entertaining and kids love it.

Did the same DNR dude that counts the deer count the dead fish? If so maybe only 200,000 are dead. Sorry for being a smartass but it makes you wonder what they are doing sometimes.

Interesting thought. I guess my first question would be how this would impact the imprint on the smolts. I really don't know. My guess would be that what ever river that water is coming from is gonna' have a helluva' run in a couple of years, but the other rivers? Hmmmm. Depends alot, I guess, on the age/size of release.....or maybe not. What do ya think?

with all the computer stuff out there, you would think they could put in a few web-cams or something to get real time observations. I wouldn't think that would be to costly, and if you made a public web site we could all help monitor them.

A simple "FLOW METER" with an alarm would have taken care of that problem! :mad:

Who in the world engineers these things anyhow?? :rolleyes:

As soon as the flow of water from the pump slowed past a cerrtain GPM setting all of their alarms could have gone off!

I think a 10 year old must have designed the system :p

I was thinking the SAME thing 7mm. They probably have a voltage meter across the pump and as long as that's on no alarms. Well, if the shear pin holding the impeller to the shaft gets cut you'll have normal voltage and no flow.

D'oh.

I wonder if we can buy fish from other states? I know we have agreements with other states already to supply and receive certain kinds of fish. Maybe we can suck up some excess from someone else?

The DNR had hoped to raise some 1.2 million coho this year, all but 25,000 of which were slated for Lake Michigan.


Whats wrong with this picture?Its obvious that Lake Michigan is also the DNRs top priorty.Lake Huron I guess isnt one of them?:rolleyes: :rolleyes:

Huron has pinks and higher rates of natural reproduction of salmon species, as well as more lake trout. The die-hard salmon fisherman may not liek the lakers, but they're in the same ecosystem eating the same baitfish.

I was at a town hall type meeting with a Fisheries Biologist last year and that was one of the main reasons they gave for focusing on cohos in Lake Michigan. He also said that we raise a lot of coho and steelhead that Indiana purchase for their end of the lake.

HONOR: Hatchery gaffe kills off fish

HONOR - Business owners in this fishing and tourism village are braced for the impact of a pump failure at the Platte River State Fish Hatchery that killed nearly half this year's coho salmon crop.
"All the businesses around here rely greatly on fishing," said Jim Ballard, owner of Whispering Creek Resort. "Especially in the fall when the coho are running, because we're trying to get as much as we can before winter gets here."
The 458,000 coho yearlings, which would have been stocked in Michigan rivers within a month, died late Sunday or early Monday when a pump that recirculates water in holding containers quit pumping water.

It will be interesting to see if perch numbers do some kind of rebound after this. I have heard from more than one persons who's opinion I respect, that blame the perch decline on all the cohos and kings that were origonally brought in to control the alwives. They contend that noe that the alwives are under control, these fish are decimating the perch population.

Hatchery failure shouldn’t hurt Munising Bay fish stocking

By JOHN PEPIN, Journal Munising Bureau
and The Associated Press 3/10/04

MUNISING — Despite the loss of 458,000 coho salmon yearlings in a downstate hatchery pump failure last weekend, salmon stocking for a pilot program in Munising Bay will continue as scheduled this spring.

“Because the Department (of Natural Resources) is committed to the pilot stocking program for the next five years, they will stock it at the 25,000 capacity this year,” said Munising’s John Madigan, a member of the Natural Resources Commission, the rulemaking body for the DNR.

Last April, the DNR stocked just over 25,000 coho fingerlings in the Anna River, south of Munising Bay. The effort was made to diversify fish populations in Lake Superior in an attempt to relieve some sportfishing pressure on lake trout.

During the pump failure at the Platte River Fish Hatchery, the DNR lost nearly half of this year’s coho salmon production. The 458,000 coho yearlings, which would have been stocked within a month, died last weekend when a pump that recirculates the water in the raceways continued to run but quit pumping water, Booth News Service reported.

Because the pump’s motor was running, it failed to trigger the alarm that would have alerted DNR personnel at their homes. No one was on duty when the pump failure occurred, sometime between 4 p.m. Sunday and 7 a.m. Monday.

The hatchery is undergoing an $8.5 million renovation. The yearling cohos that died were the first production cycle of the newly renovated raceways.

‘‘We know what the problem is, and we’re rapidly fixing it,’’ said Gary Whelan, who runs the DNR’s hatchery program.

The Platte River facility near Beulah is the only state hatchery dedicated to coho salmon. The DNR had hoped to raise 1.2 million coho this year, all but 25,000 for Lake Michigan. There are 610,000 fingerlings left at the hatchery, almost all of which will be stocked in the Platte River.

The weir on the Platte River is the only place the DNR collects coho eggs. It also collects eggs for Wisconsin, Illinois and Indiana hatcheries.

The cohos were to be planted in Lake Michigan at the Galien, St. Joseph, Boardman, Grand and Manistee rivers as well as Portage Lake. The additional 25,000 were planned for Munising Bay.
Madigan said the DNR will acquire coho yearlings from other hatcheries to stock Munising Bay.

“Because this is a five-year pilot program, it’s critical that we keep planting that same amount each year so it doesn’t skew our results,” Madigan said.

The hatchery accident should not affect fishing this year.
‘‘The anglers will feel this in 2005,’’ Jim Dexter, the acting chief of fisheries for the DNR, said. ‘‘There will be a decline in the catch. (But) this should not have any effect on our egg-taking capabilities, which is of primary importance.’’

The accident will also not deter the efforts of the South Shore Fishing Association, which is trying to secure coho plants of 100,000 fish for Lake Superior for five years.

“We didn’t expect to get anything this year,” said Dan Cook, president of the association. “We’re looking to the future. Lake Superior has just got to have more (coho), whether that’s in Marquette or Munising.”

In years past, coho stocking was done at many Great Lakes ports, with disappointing results. Munising Bay salmon stocking was stopped in 1993.

State fisheries biologists say that no changes have taken place that would necessarily make the coho stocking more successful this a time around. In fact, there are several problems involved.
Natural strains of salmon typically compete better than hatchery fish in the food chain. Lake trout numbers, both fat and lean varieties, have increased in Lake Superior and those lake trout have been preying on small salmon. There are also new concerns about declining forage bases for predatory fish in the Great Lakes, Scott said.

But despite these potential drawbacks, fisheries experts want to experiment with Munising Bay. If the program is successful, the coho stocking efforts will continue.

Beulah is located in northern Lower Michigan, about 30 miles west of Traverse City.

That's an issue that concerns me. In the interest of having this salmon fishery, are we putting the indegenouus fish in peril?

I'll tell ys whats been decimating the perch, them darn muskie in LSC!

Them muskie are just eating machines and what makes it worse is you can't even eat a muskie. Stinky and contaminated. Completely useless creatures. Just as bad as cormorants IMHO. I say we should put a bounty on both of them.

:eek: ;) :D

(just kidding ESOX)
