Someof the rainbow trout in our iLab are already 4 cm long. We have almost 100 trout sharing the 55-gallon tank.
One of our favorite parts of the day is feeding the trout. The photo below shows how eager the fry are to get their food. It’s fun to watch the trout leap to eat the tiny pieces of food that float on top of the water. This reminds us that the trout will be eating a lot of water insects in their natural habitat and the jumping they do in our tank gets them ready to compete for food in for the real world.
Our trout will be released into the Gunpowder River by our fourth graders on April 29.
I think the trout are so cool. I was a part of trout patrol last year, and it was so fun doing everything.
How do you get the picture of that fish?
Hi Mikey,
I took a picture from the top of our tank while I was feeding the fish. I have an option on my camera that allows me to take REALLY close up photos, and this one turned out great.
I enlarged the picture when I posted it. The trout was only about 1 1/2 inches long, but it looks much bigger.

The trout look like a very interesting topic to learn about. This looks very fun to do. How long does it take for trout to grow? What is the trouts lifespan in the wild?
How long does it take for the trout to eat all the food?
Hi Daniel,
We only fed the trout a very small amount of food at a time (4 big pinches of food), so they finished eating in less than 5 minutes.
Thanks for the question – it’s a great way to get a conversation going on our blog.

I think the picture is pretty funny to look at, but I do not blame you.
This is artificial, but it needs a little something.
This is not fake, we went here and the trout was small and it was great! 😀
I know, a great blue heron!
Hi Manning,
I’m not sure what you mean in your comment. Can you clarify?
One way I’ve learned to make my comments more clear is to write the question that I’m answering in my comment. Here’s an example:
Susan asked in an earlier comment, ” How big to trout
get?” …. The largest rainbow trout ever recorded weighed
over 40 pounds! It was caught in western Canada.
Hope that helps,
🙂 Mrs. Austen
I like the pictures of the trouts they are growing fast. You should keep up the good work.
Wow that’s alot of trout! Wishing them a safe life!
Thanks for raising Rainbow Trout!
Wow these trout are growing and growing and growing!
I cant wait for thease trout to be released!
I cant wait to release the trout. It will be a blast!
Hi Emma,
Now that we have released the trout, what did you enjoy most?
For the Stranger at the Lake I liked how the stranger got arrested. It’s good that Marven and Marian didnt go with the stranger.
Will each 4th grader get to release a trout?
I liked the pics that showed how well you treated the trout.
I wonder what Jerusalem Mill looks like. I bet that it will look like a valley and a river or lake beside it. I can’t wait for the field trip tommorow!
I hope the trout will survive in the river against bigger fish or bigger trout.
I haven’t seen the trout in a long time. I think they’re going to be very big. Big fishy!
I wonder how many trout will be released. There might be more than 500! How big could the trout get? Could they be more than a foot? I hope so!!
I left the Trout when they were very small (1 cm). Now they’re double the size! I think that they are going to do very well in the wild. Good luck Trout!
How many eggs can a female trout lay? How many kinds of trout are there? I hope the trout give us each a caddis fly.
I can’t wait until tomorrow when we release the rainbow trout. I wonder how much the rainbow trout grew. It’s going to be so much fun!
The trout are going to leave us and go to Jerusalem Mill. I hope the trout live for a long time. Fight Back Trout!
We really learned a lot on our trip to Jerusalem Mill today!
*We learned that the predator hunts for prey. – Michael H.
*It is more difficult to survive when food is scarce. -Austin F.
* If a fish stays still, the predator won’t go after it. -Blake D.
*Small insects eat leaves. Minnows eat insects. Then the trout will eat the minnows. -Emma C.
*The top of the trout is the color of the sand and the bottom of the fish is the color of the sky. This is a way they camoflagh so they won’t be eaten. -Beulah L.
*Baby trout are called fry. -Annabelle L.
*Worns can live in dirty water but, not clams. Clams can only live in clean water. -Natalie O.
*Trout can be eaten by bigger fish or bigger trout. -Sebastien
*Lots of insects and fish live under big rocks. -Ally M.
*Our hike, I saw frogs camoflaghed on tree stumps. -Katarina D.
*On our hike we saw a big snapping turtle. -Blake D.
Oh, I just simply love trouts and the Gunpowder River field trip for the 4th grade. I hope the trought get to live for a long time. As a 5th grader I personaly think that the trout is a fun biology, learning experience for the 4th graders. I hope the kids agree so too. Good Bye!
I liked when I let the trout at Jerusalem Mill. I learned a lot of new things about trout.
I liked the pictures of the trout. The trout look bigger then they did before. The trout are different sizes.
Wow! Our trout have grown so much! Stay safe in the rivers!
I like how your trout are growing fast!
I really miss seeing those trout. I just wish that maybe iI could see them again one day. 🙁
