It's not about "Shark Shields" or Cages! It is about personal choice and responsibility! If you don't want to do it then don't, but if you do you should be able to!

The sharks doesn't know it is being chummed, whether from fisherman cleaning their catch or a fishing boat, they just know there is new opportunity! Sharks associate food from behavior, if you act like food then they will test to see if you are!
