The eggs have hatched!

On Tuesday our trout eggs hatched. Thus far the egg mortality has been one egg out of about 1,000 between our two incubators. The trout are in the alevin stage which means they currently have egg sacs attached to their undersides for nourishment. The alevins are very light sensitive right now, and to accomodate this, our incubators are covered with laminated tagboard. Our students in teams of two are testing the incubators for ammonia and pH levels as well as recording temperature data and observations. Stay tuned for more fishy developments.
