Feeding of sharks has the effect that it can get rid of that natural concern between the shark and human, or, in some cases, teach them to equate the human with free food.This is an example of a classic Pavlovian scenario where you ring a bell and the animal starts salivating.There are examples of sharks in shallower water learning to respond to the sound of the boat’s motor. Meaning the sharks are drawn closer to areas populated with humans, increasing the risk for human attack. The sharks though did not change their migration patterns because of food they received from divers.
There can be a negative effect as well: entrainment of animals, alteration of natural behavior, and alteration of the ecology of the area. It’s going to alter the feeding dynamics of the whole food web, and it’s a change of natural behavior. Around 100,000 sharks are killed each year for their fins or as by-catch by the fishing industry, and increased awareness of the issue could contribute to conservation efforts.
