In the spirit of Shark Week, I wish to ask a shark-travel question for an upcoming trip. I am hoping to do some shark cage diving while on a vacation to Hawaii next April, and I was wondering which Hawaiian Island has the highest shark population (or if it is more or less the same throughout)?

Are certain species of sharks more highly concentrated at specific islands? For instance, is one more likely to see bull sharks, tiger sharks, and hammerhead sharks in the waters around Oahu?

We are travelling in April (spending most time in Oahu), and are curious if that is shark-cage season? When are the shark populations at their highest and when is underwater visibility at its best?

Note: I know shark-cage diving is controversial, but I heard there are companies out there that do not do illegal chumming to draw the sharks attention -- I'm not quite sure how they do it. But I'll make sure I go with an ethical company. enter image description here
