Trout In The Classroom

You raised a trout.
Then you let it go.

It started as an egg in your classroom in the late fall. In the spring it swam out of your hands into the Lower Illinois River. Here's what happens to it now, and how you can come back and find it.

What You Did

From Egg to River

You and your classmates kept a tank of trout alive for several months. That is genuinely difficult. Keeping the water quality high is the goal. Here's the journey your trout took.

1

Egg

Tiny orange eggs arrive in late fall. Cold, clean water is everything to the tiny embryo.

2

Alevin

They hatch still carrying a yolk sac, like a packed lunch. They hide on the bottom and don't eat yet.

3

Swim-up fry

The yolk runs out and they rise up to feed for the first time. This is a critical time in the trout's early life.

4

Fingerling

About as long as your finger. Finally strong enough for a real river with real current.

5

Released

You carried it down to the water and opened your hand. From here it's on its own.

The Honest Part

Most of them won't make it. That's what makes yours matter.

In a wild stream, a female trout lays 3,000 to 5,000 eggs. Only two or three will live long enough to have babies of their own. It's nature's law of survival of the fittest. That's not sad, it's how nature and a river work.

So, the fish you let go is already a survivor. It got further than almost any wild egg ever does, because for a few months you were the one keeping their water cold and clean.

Where Your Fish Went

The Lower Illinois River

Your trout now lives below Tenkiller Dam, near Gore, Oklahoma. Water drawn from the bottom of that lake stays cold all year, and that is the only reason trout can survive in Oklahoma at all.

It will eat the same bugs you studied on your journey to the river: mayflies, caddisflies, stoneflies, scuds. It now shares the river with darters, sunfish, sand bass and striped bass. Plus, you took notice of the birds and plants that thrive in the river valley.

You can go back. The Watts Wildlife Management Unit (WMU) where you released your trout is a public area. All are welcome to walk in and enjoy the cool water and maybe catch a trout. Could it possibly be the one you released? Maybe, just maybe.

The Team Who Keeps The Water Cold

You probably met Scott Hood

Scott, and a team of volunteers from the Dave Whitlock Chapter, is the reason your classroom had a tank at all. They installed the aquarium and the chiller, the machine that keeps the water cold enough for trout to survive in a room that is nowhere near a river. Then they keep it maintained all year, checking on it and fixing it whenever something goes wrong.

They answer many questions along the way, and many volunteers are at the river on release day. They do this for classroom after classroom, every single year, for over a decade. It's a labor of love for volunteer members of the chapter who decided a long time ago that kids should get to watch this happen up close.

If your trout made it to the river, Scott and the team of volunteers had a hand in it. Say thanks the next time you see a Trout Unlimited member.

Nobody remembers a worksheet about trout. They remember the day they let one go.

For Parents & Teachers

Who put this on?

We're TU420, the Dave Whitlock Chapter of Trout Unlimited, here in Tulsa, OK. Trout In The Classroom is run start to finish by volunteers from the chapter and paid for with raffle tickets, private donations and various fundraisers throughout the year. Nobody gets paid for this. Volunteers install and maintain the classroom aquariums and chillers, keep them running all season, and many are there on release day.

We also do river clean-ups, water quality monitoring, free fly-tying nights, and beginner fly fishing clinics. If today landed well with your child and they can't stop talking about it, you need to know that most of what we do is open to families and costs nothing to attend.
