Today the trout eggs began hatching. When I arrived at school this morning only a few had hatched. They are pictured below.
Each class had taken the first 3 minutes of class time each day to date and draw the fish eggs. Today, they were all happy to see that when I place the petri dish under the document camera, that there was an actual, living, swimming, trout!
By the end of the day almost all of the trout had hatched as seen below!
As they hatched they left behind little clear egg sacs that had to be cleaned out quickly so that they would not began to decay. When they begin to decay, it changes the water balance. I have have students who check the pH, Nitrates, Nitrites, and Ammonia levels everyday. At the end of the day today all of our levels looked great. I couldn't be any happier! They were also fed fish food for the first time today.
