Let's make some fish!

At the Linesville Fish Hatchery open house, we had the pleasure of seeing how fish are made!

Don't pick the males off the tree yet.

Males + Females = Eggs! If you look closely, you can see some of the babies (literally small fry) swimming around.
That's how many.
One of these guys is not in the Future Scientist program. Can you guess which one?
(Hint: radioactive skin)
Can you find the golden rainbow trout?

Speaking of golden rainbow trout, you can read more about the interesting selective breeding process that created this creamy delight at this Pensylvania Fish and Boat Commission page. Apparently, all golden rainbow trout alive today were derived from one oddly colored individual back in the 1950's. Wackygenes!
