Some of our eggs are hatching into alevins. Egg shells are visible within the hatching basket. They have a large belly of stored food which allows them to grow and survive without food. By the end of the week, all of our eggs will hatch.
The brook trout “green eggs” are laying in the hatching basket within the tank. They are receiving a good amount of oxygen and need darkness to grow. We keep the tank covered until they hatch into alevins.
To separate the viable (fertilized eggs) from the non-viable, we used a turkey baster to remove and count them one by one; then we placed them into the tank. We’re starting with 316 viable and 124 non-viable eggs this year.
We received our brook trout eggs in the mail from the Benner Springs Hatchery. They came in a Styrofoam container with an ice pack inside, and the eggs sealed in a waterproof plastic bag.
The Trout Tank is up and running with the chiller at a frigid 52 degrees F and the filter and air pump working hard. We await the arrival of our trout eggs from the hatchery in a few weeks.
These are some of our Brook Trout Eyed Eggs. Once eggs have been fertilized they are called green eggs, one of the most fragile life stages for the trout. As they develop, their eyes become visible. We have about 300 eyed eggs in our classroom tank.
