Testing if Sharks Can Smell a Drop of Blood

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.

    He says Disney sits on a throne of lies after he tests the human blood, but the sharks loved the cow blood. And if they loved cow blood how much do you think they’d love fish blood. In the movie they loved fish blood. Their natural prey.

    You need to simulate movement or water friction. Its preditorial for them to attack prey that is injured. They just figured out it was a board. And decided it was either not fresh prey or garbage

    I can't help but wonder if the proximity of the boat skewed your data, as in most of the big wide shots that showed the surfboards indicated that there was a ton of sharks next to the boat.

    I believe the boat was distracting them. Pretty sure those sharks are used to tourists throwing food for them. So maybe they were a bit distracted.
