Shark Culling Research Paper

Shark culling is a state government implemented policy in which sharks within the vicinity of a beach can be legally killed through shark nets or drumlines or a combination of the two. Drumlines are unmanned buoyant drums anchored one kilometre of a beach's shoreline. In between the drums are ropes with hooks. Drumlines are baited so that if a shark is swimming in the vicinity of a beach it would be attracted to the bait and not humans. Each state has different policies on drumlines depending on their state government. A shark net is one that is submerged around beaches to reduce the chance of a shark attack. The net forms a partial barricade and aims to entangle and capture sharks of targeted species, through holes that entangle sharks over two metres.
Shark culling is being carried out in Australia with the desire that those using the beach and its water for recreational activities are less likely to be attacked. It is also thought that shark culling is in place as Australia's tourism is heavily reliant on eco-touristic activities. The principle of shark culling is: the more sharks …show more content…
Dinoflagellates are marine plankton, they are producers and have eukaryotic cells (meaning that the cells have a nucleus). Diatoms are unicellular, they are a type of algae. Cleaner shrimps free other organisms of parasites. Copepod are small crustaceans found in marine ecosystems. Ptereopods are a type of sea snail/slug. The type of squids, sharks and small fish found in a marine ecosystem depend on the abiotic elements. Amphipods are also a type of crustacean found in saltwater and fresh water habitats. Marine ecosystems follow an incricut and delicate food web, an example is shown to the right. Shark culling through out the delicate balance of the
