Why are there always fish living in an outdoor pond? Where did this fish come from? It can’t be seedlings planted by humans!

If there is a layer of sand and gravel underground and the water level is suitable, fish eggs will flow toward the pond. I remember back in my days as a youth sent to the countryside that shrimp could be drawn up from the wells of households near the river. Besides that, it’s impossible for fish and shrimp to appear on their own.
Before the 1980s, there were more fish in wild ponds than you could imagine. . . . . . Rainwater and wind can both carry fish roe into the pond
Some say it’s because of the birds……
Waterbirds are one of the main reasons.
