Not the exact spots. Each angler chooses whether a catch shares the exact spot, a general area or just the name of the water, and no paid tier shows anyone more. Pages like this one show the species and a rounded count, never a spot.
They depend on the species and the season. When you log a catch, Cobia names the species from the photo and shows the slot limit, bag limit and season for that species where you are standing.
