As a Zoologist, I am impressed with all of your knowledge.

I have backpacked fry into numerous alpine lakes (and hopefully C&R'd them later) and seen many others do the same.

natural populations occur by connection of waterways, sometimes thousands of years ago.

Sorry to ruin the myth here, but fish eggs cannot survive the digestive tract of a bird....not even under the best circumstances.

Nearly all of the fish you will catch will be small and will either be plants or the offspring of plants.
