Urchin raking is a diving method which uses hookah and air hose and an urchin rake to remove catch from the rocks. Air is pumped through a hose to the diver who is working along the seafloor collecting their catch. Divers collect their catch using an urchin rake to remove the urchins from the rocks and place them into a catch bag. Catch bags have a parachute attached which when full is filled with air to float to the surface for collection by the boat’s deckhand and packed into bins on the boat. This method allows for highly selective harvesting, whereby under sized catch is able to be put straight back in the same position on the road where they were sitting.
