Many fish-Lots of Foam

This is the first weekend that the TIC aquarium has experienced since we got the eggs. We checked it Sunday afternoon and found many alevin swimming around. There seems to be more of them than eggs now.

We also saw a large amount of foam in the water. I quickly checked the ammonia level but it was fine. I went ahead and changed about 20% of the water just to be safe. I know the kids will be excited when they come in tomorrow and see all the trout.

It's Hatching Time

It looks like it is hatching time. We saw several alevin today hatch from their eggs. At first we thought that the eggs were dead because they were white, but as it turns out, these were the egg shells left behind by the hatching trout. If this rate continues, we should come to school on Monday and be greeted with a large number of swimming fish. Lets hope that is the case.

Live Ones and Dead Ones!











Today we had good news and bad news. The bad news is that we found our first dead eggs. A total of 5 dead eggs were removed including one that hatched but the sac-fry (alevin) was born dead. The good news is that we have 3 live alevin. They are still basically motionless and sitting on top of the rest of the eggs so they are hard to see.

If you look carefully in the photos above, you will be able to see the dead alevin in the beaker.

Getting to know our Brood

Some classes took their first good look at the trout eggs today. Some students estimate that there are close to 400 eggs. That seems a little high to me but we will see. We think we spotted our first "white" egg which means that it is dead. We will check on it tomorrow. All readings are good (pH, Ammonia, Nitrites and Nitrates.
