I've chimed in on this subject in the past but it will never go away, so I will put my 2 cents in again. I am not aware of any scientific proof or notation supporting the stocking of fish or fish eggs by birds into previously "fishless water". I am in northern California in the middle of what is arguably one of the most fertile fish areas in this country. My pond is less than 200 yards from a fertile brook (about 100' in elevation above it). In addition there are numerous ponds, creeks and lakes including Clear Lake within minutes of flight time of my pond. My pond was 18 years old when I bought the property and there was not a fish in the pond. It was absolutely full of frogs and other amphibians and more insects and larvae than you could imagine. It was also home to a variety of waterfowl which would be the likely vector for transplanting fish or eggs. I stocked the pond and in 6 years was catching truly huge fish, so fertility of the pond was not an issue to explain the sterile fish enviornment. I have subsequently met several other people in the area who have had the same experience as me. I am not suggesting that this is proof of a theorem, but the number of reported spontaneous eruptions of fish will always be suspect to me. As a younger person and particularly as a teenager I was always spiriting fish into strange waters, and while I started growing the odd hair in new places then, they never looked like feathers until recently.
