Silly Salmon Savers

Where Do We Come From? We are students from the La Center School District, which is located North of Vancouver. We are located in Clark County, like many of you here today.

What Do We Do? Once a month we water monitor with the high schoolers. We do this to make sure our streams

are safe for the wildlife, such as macros and salmon. We check the amount of chemicals that

our community puts into our streams.

A Little About Our ProjectsAlong with water testing

in two spots, we also raise salmon in our

classroom and in our Remote Site Incubator (RSI)that is located at

one of our testing sites.

What is a RSI?A big box that contains water that is

brought in a big tube from up the creek. This tank allows us to raise not only salmon eggs but fingerlings as well. When our salmon are big enough to

survive on their own we release them into our local creek.

After releasing over 1500 fish this year our water testing group has

come up with a hypothesis.

HypothesisIf our Dissolved Oxygen(ppm) and our Turbidy(cm) levels are

high, then the probability of salmon survival in our creek

will increase because the salmon will be able to breathe

in the water.

What is Dissolved OxygenD.O. is the amount of oxygen that is dissolved

into the water. Allowing fish to respirate.

Dissolved Oxygen

What is Turbidity?A turbidity tube is measured in cm

instead of what is commonly used(NTU’s)

Turbidity measures the clarity of the water.

As eggs, fish need to have high turbidity. If

the turbidity is low, this means that there

is more sediment, which will coat the eggs

and suffocate them.

Turbidity

Straw ActivityTake a straw. Hold it firmly in your hand while running in place for 30 seconds. Once you are done running, place the

straw in your mouth and try to breathe.

Which is easier?...with or without the straw?

It’s harder with the straw isn’t it?This is how salmon feel when the turbidity and D.O. levels are low.

Conclusion

We have concluded that our hypothesis is correct. Looking back at

previous years we have water monitored, we saw that more salmon have returned to Brezee Creek on the

years that had high D.O. and turbidity.
