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

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.

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.

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.

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!

The Ph is  good and it is 7.2 

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.

 

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.

But the trout are doing fine and well. 

This pic will show  you the dead fish and eggs    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!

Check pHCheck the NitratesCheck the ammonia

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.

We 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).

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

Our 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!

 

 

The trout are about 3/4 of an inch. We released them into the big tank and they are in the fry stage. This week only one trout died. Next week we are switching to size one in food.
