More info that was promised-
What is likely happening is that the sharks can smell the blood but it's just not in a quantity that is interesting to them especially since they don't love human blood that much (btw, I spoke with a marine biologist and mammal blood is all the same from a chemical marker stand point so cow blood is a suitable substitute for human blood). If I did the experiment again, I would want to test human blood vs. fish blood.

This is the most definitive study done to date in a control lab environment on what is least and most interesting to them: The Biology of Sharks and Rays Peter A. Klimley and Steven Oerding; ISBN-13: 9780226442495. Particularly pages 134-140. Figure 6.7; Table 6.2

Summary: I've always wanted to test if sharks can really smell a single drop of blood in the water from 1 mile away. So I went to the Bahamas in shark infested waters and set up an experiment to get to the bottom of things.

    I once found a sharks head in some coral,it had a hook mark on it ,some ahole had evidently caught it and cut its head off. It was small,a whitetip. I picked it up and headed back to the boat to show my colleagues. I never thought about the blood that was coming out of it ,green in colour of course. Then the sharks started to arrive,and were clearly switched on,not just cruising. There is noo doubt the blood attracted them,though from what distance out i dont know.

    For anyone worried about sharks it's not the blood they care about. They just feel the movement of you in water splashing about an come to check it out. But since they have to hands they use mouth. If they can get it to fit they eat. If too hard etc they leave it be. Their actually evidence to say they actually hate taste of human flesh. Hence shark attacks are just a bite. Which can be fatle depending on size of an number of shark. If are a group of sharks you in trouble cause they'll all wanna see what new toy in aka all wanna put new thing in mouth. And us kicking am failing about just attracts more or the sharks think playing like you saw them do with each other headbutting and mouthing each other.

    You didn’t account for the fact that your boat was a huge attraction/distraction for the sharks. It seems that in the first experiment it was only after the sharks noticed the smaller fish attracted to the blood that the sharks then showed up. If that boat is designed to take tourists to look at sharks, then those sharks have essentially been trained to show up when that boat arrives.
