Our trout are alevin stage and we started to feed them size 0 food. They are doing well.

The trout

Today the trout are doing well because the chemistry is good and none of them died because they are healthy. Here is a picture IMG_6187

The trout

Today the trout are good none of them died. The PH is good it is 6.6. Also, the ammonia is 0.25 and the nitrate is 0. Also the trout are healthy and are getting larger. They are now 1.5 to 2 inches long.

Twenty-four Trout Counted Today

We are measuring and recording the trout length in cm.

The longest trout was 3.2 cm. We also counted the fish and found that we have about 24 trout in our tank. This was difficult to do because the fish are always moving and there is also a reflection under the fish that swim near the bottom of the tank.

Trout Update

No trout died you can see the picture on the bottom left the trout are doing good.



The Nitrate was 20 and that means they have been eliminating a lot and the Ammonia was 0.50. We did a 7 gallon water change to clean the water.

GEHMS Brown Trout Update

Update: The trout are doing well.  They actually do have stripes now. However, they are also eating each other we are predicting they need more food. They are two inches long and we did the water change. We are also remembering to feed them and care for them. The ammonia level is 0.25. The good news is none died today, so there should be about 30 trout still alive.

The temperature is also 55 degrees. The nitrate level is greatly increasing from what we’ve had.

Thank You, 4th grade and Teachers!

Trout Team trains new scientists!

The Ph is  good and it is 7.2 IMG_2966.JPG

this is the picture friend with the Ph. we did 3 water changes that were fresh. the temp was 56 degrees the nitrate was 0 and ammonia was 0.25 . The feeding time was 12:34. We lost 1 trout.

Brown Trout Update


Today we noticed that there were 2 dead  fish and 1 dead egg.

The Ph was 7.0, ammonia was 0.25 and the nitrate was 0ppm.

Because of the ammonia we had to do a water change we  dumped 2 gallons of fresh water.img_2901

But the trout are doing fine and well. img_2900

This pic will show  you the dead fish and eggs  img_2902  If you have any questions or suggestions about our trout please leave comments below.




Students at GEHMS use a camera and computer monitor to view the growth process of tiny Brown Trout in our school life science lab. Our third graders in the photos above have lots of observations and questions about the tiny fish.

Thank you, fourth grade scientists, for taking such good care of our small, delicate Brown Trout!

How to take care of Brown Trout

Check pHimg_2813Check the Nitratesimg_2811Check the ammoniaimg_2810

Today our readings were all good: pH=7.1, Nitrates=0 ppm, Amonnia=0 ppm. We did not change the water because the chemistry today was perfect for our small Brown Trout.

img_2822We noticed the eggs that  need to be removed. we also noticed the eggs sacks on the trout’s stomach; this is what they feed on. We had to take about 12 egg cases out of the fish basket (see photo above) where the small fish or alevin  are growing.

We also noticed that some were dead egg shells (see photo above).

img_2809We have to take these out or the egg cases will rot and decay and they will get bacteria in the water.

img_2808Our questions:

How long can  trout  live and grow? And by these pictures you can see that the trout are doing well.

If you have any suggestions for us please leave a comment on our blog. Thank-you!
