How often do fishing spots move?

I'm looking for bream and I wanna know how often to check back.

fishing spots don't move. try different equipment and different times.

Ah, so that's what the times meant on the wiki page. I'd just assumed that meant you needed a fishing spot at x place, at x time, to catch x fish there. Thanks!
