In our Classroom

    • Eyed Egg Stage

    • When you can see the eyes the eggs are more hearty and better able to handle transportation to their new temporary home in our school

    • The  eggs need to be checked at least two times a week so the dead can be pulled out of the group(we did this so if a dead egg is left in the aquarium it may begin growing harmful bacteria so because of the eggs being close together, the bacteria can easy get into to the living eggs.  

    • Alevin Stage

    • This stage is the stage where the fish has come out from the egg but the egg sac is still attached to the fish

    • during this stage, they do not move as much and all of their needs(nutrients, food etc.) come from the sac

    • Over the time phase of this stage, the sac shrinks and becomes part of the trout's body

    • When the trout can start to swim to the surface they are entering a new stage called the Swim Up phase, this alerts us to start to feed the fish

    • Fry Stage

    • During this stage, the characteristics of the fish look more like we think of as a brook trout

    • Before this stage, they had to be in-between insulation to keep the temperature low

    • Once the trout are fry they can be removed from the small holding tank and will be allowed to swim around the rest of the tank

    • Now during this stage, we will feed them 2 times a day and their production system is more consistent so then there is more of water changes and the water chemistry comes more tricky 

    • the fish are about one inch in length

    • Fingerling Stage

    • The trout are increasing in size

    • At the beginning of this stage, we release the trout into their natural habitat

    • We will do this at the Middle of May

    • Adult

    • Their life expectancy is not as longer than 3 years

    • During this stage they get a square tail, red dots surrounded by blue halos, reddish belly take form
