Do you maybe mean something like a fish ladder?

Am I seeing that right, they have a guy stand there, pick fish up, and load them in to a pressurised cannon?

I wad expecting something a bit more sophisticated/under the fish's control, even given the name!

Can all fish jump? Feels like it may be something that salmon are pretty good at, but a gigantic fish may not.

Jumping is not always necessary. You can get an idea of possible designs for fish ladders from the photographs in the section "Types" in the article.
