According to the research, they say when a great white die, the other great whites in the area will dive deep down the ocean to avoid being killed. That was the results they found when the killer whales killed one of the great white, all the great white disappear for a long time and avoid going back there. If that's true, the Australian government does not have to kill a shark, all they have to do is to release some similar pheromone to simulate a great has just been killed. However, will this attract the killer whales is another issue.:scratch::eat::fishhit:Wondering how to kill a shark without attracting more sharks.
It makes sense that more people are being attacked since overfishing will be depleting the normal if random diet of pelagic sharks. This will bring them inshore and when they get around people they will take a bite.
