We are raising Eastern Brook trout in the classroom. We received 350 tiny eyed eggs from our state’s fish and game department in January. We needed to keep them in cold water, 43 degrees and dark – like they were under the ice. This is what they looked like then.
Finally in late February the eggs hatched. We had little sac-fry that fed on their yolk sacs for about 6 weeks. They could only wiggle and looked liked little poly-wogs. Finally they have fins and are swimming, so we can now feed them for about 6 weeks before we release in the wild.
