Question

How do fish get into a pond that hasn't always had fish?

Answer 1

They swim. When the pond over flows fish swim up or down stream to populate new water. It only takes a scant inch or so of water for tiny young fish to swim in.

Some say fish eggs are carried by birds and that fish are swept up in storms and dropped. I doubt either case is correct.

Answer 2

Someone sneaked it in - or was the area flooded recently?   Perhaps there is a stream or river nearby, flooding could be your answer

Answer 3

people introduce fish there

you can go out an buy lots of smaller fish an harvest them in the pond

Answer 4

One of two ways, either the pond is stocked or someone threw a used condom in the pond.  Givin the right sunlight, food and shelter, the little sperazoids can become minnows.
