Default How do fish become established in new water?

I found a number of threads in the archives discussing possible ways of fish or fish eggs being transported from one body of water to another. Here is another possibility that has some backing by science. Fish eggs are being eaten by Mallards (in lab conditions) and remaining viable when pooped out!

Hmmm Chinese bbq duck and the bucket brigade. Maybe there’s a connection.!

Actually that’s a pretty interesting finding. I always wonder how a field can be dry for years, then one wet spring it’s full of frogs. Nature is resilient.

Eagles and other birds of prey can catch fish with eggs and loose them over other water bodies, probably not to common but crazier things happen in this world.

In the case of snakeheads I think they will just walk to the next waterbody.

Wondering about that myself as I'm mowing the lawn. Lots of the little buggars around but no obvious source.

I’m excted with this higher water connecting with back channels. Recharge the fish numbers.
I was hiking the edge of Beaverhill and noticed sticklebacks swimming up a flooded cow path. Followed it several hundred yards where the water was boiling with them. I assumed they were spawning. That path could be parched for years with spawn?
A drive out east one time looked like a massive grass fire. Turned out to be a dried out lakebed lifting and travelling downwind for what could have been a hundred k and more. It was dark, indicating substantial material being transported.
And then there’s that person that figures it’s ok to let a fish go somewhere it don’t belong.

I uunderstand that frogs burry themselves in the mud and basically turn themselves off
