I think that there should be some sort of notification of how many whirlpools left. Sometimes the location doesn't change for a while and you don't know if there are any left. Or something like once all whirlpools are fished up it automatically resets to a different location. I enjoy doing whirlpools but once we clear out an area, we have no clue if there are any left or whatever. I also dont want to go blind looking for them if there arent any left lol.
