Got Fins!

Our trout are continuing to grow.  Everyday students will comment I think one is dead it is just lying there.  No the trout are not dead!  Right now the trout are feeding off their yolk sac and they have no fins.  When they first start to develop, they really don't move on their own unless disturbed.  However, as of today they are starting to move a little more.  If you look closely, the alevin have a white border around them.  This is not fungus but actually their fins starting to grow.  Once their fins start to develop they will start to swim more.  Here is a short video clip and some photos of our trout today.

Here they are moving a little more by themselves
