about ponds being stocked by birds.?

Question

l have noticed here recently, a number of mis-informed individuals explaining how their pond was stocked by firds carrying eggs in on their feet.
once the eggs are in place, who makes the nest?
who cares for the eggs and keeps them clean and keeps predators away?
who guards the fry and also guards them from predators (including birds)?
please back up these claims with some kind of evidence other than "my grampa tole me".
l have googled and yahoo'd for days now and have found no evidence supporting these claims. they are at face value, ridiculous and those that believe these fairy tales need to have a reality check.
c'mon...l'm open to all realistic responses with some kind of back up.

This is a great question, I might have to star it! Really gets the juices flowing. It seems a little early for me to answer it just yet, mostly idiots. I want to wait and see what other people have to say about the "flight of the cosmic fish egg."

People used to think years ago that horsehair turned into eels and fishes. And they also used to think the world was flat. Maybe tornadoes could have moved them? No, no way. Although Dorothy's house did move somewhere, too. Hmm.

Ok, this seems good for now. I'll wait for another Einstein to answer.

I think you're reading too much into the whole scenario and perhaps omitting a few facts. Who give's a shhhh-- where the fish came from, they're there so what the hell are you going off for when you can get a rod and reel and give a few fish free lip piercings?  You're basically asking which came first, the fish or the egg? There are many variables to consider and science isn't an exact absolute to anything but a best guess. We all know that.
What facts? location, proximity to nearby waters, weather, flooding, human transport, indirect human or animal transport, egg casing thickness, parasitic, non parasitic, digestive tracts of  avian, mammal or reptilian and the acidity  in relation to eggs species of fish. I can go on and on  and on. It'll be 7-11 24-7 up in here and I won't even lose sleep! 
What I'm saying Bass, is that everything holds true to a limit without a doubt, science is not an absolute answer and the more you look into to it, the farther from the truth you'll be. ~good luck catchin'.

I have seen two ponds stocked by hitchhiking back home in La. Fisher king is correct about the fish eggs attaching or sticking to the legs of water birds. Blue herings or sand-hill cranes were pretty much all around these areas. My friend had 2 ponds on his property, one good sized pond about 1/2 an acre and the other just a small dig out for clay material that filled up with rain water. Private property, no tress-passing signs everywhere with several mean dogs around somewhere. About 2 miles up the road are catfish and freshwater shrimp farms. Both ponds have shrimp and catfish in them now. The only thing around those ponds are the cranes and herrings, and a levey is located between the farms  and the outskirts of the town where he lives so flooding did not migrate the fish to his ponds that way. I have known about this for many years of how eggs can be transported by birds, told to me by folks that were trying to teach me things not ******** me. 40yr exp

" The Method of Exclusion"
"It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth." p315, The Adventure of the Beryl Coronet.

Birds digestive systems are not perfect. They may just be passing the fertile eggs through at their rest stops. 

More probable than falling from the clouds or spontaneous creation. Habitat is precious; species will find it, if suitable and within their ability to reach.

edit;
Plenty of creatures need only a handful to survive in a place. Some die, are eaten, or never mate. Your question doesn't state the species in question, but there are many fish that need no care from adults. Salmon come to mind.
(embarrassed) Salmon are obviously a poor example, sir. Yet,  if not a chance plunge from a bird, proving a negative is beyond my conversational ability.

Many species of fish lay their eggs  without really building a nest and then get the hell outta dodge so if the fish that showed up in the pond are members of those species then it is a slim possibility  that they cloud have been brought in stuck to the feet or feathers of birds. However most likely when weird species start showing up it's because some numb skull ( possibly trespassing) started playing johnny appleseed with his minnow bucket. We are starting to get a real nice goldfish population in some of our streams here in Kentucky and I guarantee they didn't come riding in as eggs on some birds.
