I dont know what it is, but on the last 4 dives, I've been harassed by multiple sharks. I dont know if its the "time of the year" or what. I like to collect fish for my aquarium, and mostly go down to around 130' to collect certain species. Its hard enough to focus on netting fish at these depths.....throw in a half dozen sharks trolling the slopes and i cant keep focus on my task and end up blanking out, finishing my collecting early on.On other dives, where im focused on taking photo's at shallower depths, I've noticed loads of sharks buzzing closer to normal. This doesn't bother me as much as seeing sharks when im +100', not really sure why the psychology is different.Back to my original question....does seeing sharks while you are diving change your dive?
