Because it smelt bad.
it can kill fish in the pond or it can kil people
yes, because of the smell
People's farts (at least mine) are putrid and smelly enough to kill fish. I once did this by going to a pond, stripping off my clothes and jumped into the pond. There were a few fish behind my naked butt, so I grinned and farted a huge nasty fart. I felt really relieved. When I looked back there was 3 dead fish, floating on the surface of the water.
The fish die because of the stench comming from the fart, I tested this out by going into a pond (with no clothes) and then farting, moments later fish came up to the surface, because my farts killed them

Bleach.
Yes and any fish that are in it also,
it can kill some fish or all of your fish if not treated right away
How do you want to get rid of them? If your pond has fish that you enjoy, or if garden birds and other animals are in the area, I advise you are better to keep the cranes there. Otherwise, don't taint the water by trying to kill the birds with poison and the such.
you can use a fish zapper. you can buy then at wal mart and sams
