Thompson River Stocking 1986-1991

I just discovered that the Thompson was stocked with steelhead in 1986, 1987, 1988 and 1991. Only the 1991 fish were marked with the adipose fin removal. Wasn't the fishing in the late 80's and early 90's awesome?

Found this info at http://a100.gov.bc.ca/pub/fidq/stockedSpeciesSelect.do

I'm not advocating a hatchery on the T but maybe the people who fished those years didn't know this.

In 1988 The Thompson had 80,000 stocked and the Bonaparte had 180,000. With a total of 260,000 and a 10% return that would be 26,000 fish.

and then what ?

Hi, the sad thing is THEY STOPPED !! I am all for stocking of parr but not of the larger fish. Did they do any habitat work , things like moving large size gravel up stream, creating juvenile only feeder streams ?

Stocking will help kick start recovery, but killing of these fish once they grow on will stop that DEAD !
Get the powers that be to start stocking again,then do some of the other work, GOOD LUCK

Do a Google search: negative impacts of hatchery steelhead; or something similar.

The WORST possible thing for the Thompson is a hatchery program.

A well respected steelhead biologist that I know likes using this saying:

"You have some brunettes and a few blondes, but where are the red heads?"

worst scenario is NO FISH

Hi, sorry to say it but the VERY worst scenario for the Thomson is no fish from ANY source. Stocking of fish from a hatchery is not the ideal we all know that. But a river that does not Naturally produce enough fish to be classed as viable as a fishery ( enough to give people the chance of catching A FISH every time they visit a river ) and the choice to kill and take a fish should they choose to do so, needs to have some form of help.
If you do not want a hatchery are you prepared to close the river to ALL FISHING until the stocks of fish are deemed to be large enough to start fishing again.Bering in mind that unaided this could take 20 years or more ? The natural stock level of the river could well be far less than the numbers required to call it a viable fishery!
As all rivers we need to work on them to stop them become non viable for Salmonids, as the natural thing is for a river to change form a salmonid river into a course river as it gains nutrients and silt.
Naturalization means loss of Salmonids, Sorry but fact !!!!

Brian

P.S. vote for casting for recovery

Do your homework on wild vs. hatchery salmon and steelhead in North America.

Hole in the dike

If someone around the Thompson could provide some insight, I'd like to know what the limiting factor(s) is/are for the Thompson. Have there been any substantive studies examining the decline?

What is being done to restore the steelhead runs in the Thompson? By whom?

Whether a wild fish crosses with one from a hatchery or has a different survival rate is moot if there is no spawning gravel, water quality won't support salmonids, or some disease factor has come into play.

Rather than calling on the Corps of Engineers to do a study on the chemical composition of the dike's cement, perhaps we should find the hole in dike and hire the little Dutch Boy to put his thumb there while someone figures out why it is leaking.

Anyone who fishes here in the summer will tell you there is no lack of rainbow trout in the river. Since Steelhead have the capacity to residualize and rainbow trout have the capacity to become sea-going, I can't really see the problem being lack of fish in the river. The problems ( I think, don't quote me and feel free to enlighten me) have to do with netting sockeye and chum when a majority of these fish are migrating upstream, ocean survival, etc. When the water temperatures go up and there is more nutrient runoff, the river becomes more fertile, better for the local trout. Why would they leave if there is all this food around?? there are a number of problems facing this river, but dumping more fish in the river is absolutely not the way to fix things. If you believe that to be the answer then you need to open your eyes a bit

Cheers

Please Educate ME

Hi J.G , WHILE I COMPLEATLY agree with the idea of wild fish in wild rivers,THERE IS NOT ONE river in North America that has not had some kind of human caused problem on it. Nutrient enrichment, toxic metals, abstraction the list goes on !
From what I have read on these pages stocking of rivers in the states has not had many good results. The biggest and saddest thing is the need to supplement wild stocks.
Peter Grey , who has had GREAT success in restocking the river Tyne (UK) has been asked to help to stock an American river ,his approach is different to the ones generally used in the states.
I have a great deal of experience of working on restocking projects in the UK. I have NO EXPERIENCE in the states.
PLEASE ,PLEASE educate me on how stocking has taken place , and why you think this has failed.

All I and other pro stocking people want are rivers with goods runs of fish.

Thanks

Brian.

OldStyle,

I think the idea here is that we want to protect the Thompson Steelhead. Give that hatchery programs have been shown to have a negative impact on wild populations of steelhead that is the main reason why so many of us are against it on the Thompson.

We all want good runs of fish, but I'd requalify that to say we want good runs of wild fish.

I DO understand the wild / stocked difference

Hi Roseph, I fish for wild brown in Ireland, Scotland and Wales, while maily stocked in England. Yes they ARE totally different.
What has happened on the Thompson I DON'T KNOW ! Several things might have gone wrong, choice of brood stock, size at which fish are stocked , nutrient enrichment of the water leading to excess of food.Leading to 'slob trout ' ( migrating stock which stay put )
If you now have resident rainbows instead of steelheads it will be hard to increase steels, as these rainbows will eat many of the young 'steels '

Improve water quality, reeds. shallows/nursery areas , kill all rainbows which do not go out to sea.

GOOD LUCK

Brian
