Second grade is currently learning about Brook Trout. They have gotten them in a box through the mail in the end of October with food, and ice packs. They had to sort the eggs out and throw out the ones that were dead. There were 186 live eggs, but they got 200 eggs in all. The trout also have yolk sacs that keep them alive.
Right now the trout are called Alevin. That means that they are growing tails, they are starting to grow fins, and they don’t have a mouth yet. They stay Alevin for about 2 to 3 weeks. Then their yolk sacs grow smaller because they now have mouths. And they start to swim up. The second graders are going to name the first one to swim up. That is the Fry Stage.
Can you find the tree brook trout? 🐟
