As a result, more than 100 million are killed by human impacts each year.At this rate, sharks are quickly headed for extinction.
The shark’s critical role As the apex predators of the oceans, the role of sharks is to keep other marine life in healthy balance and to regulate the oceans. Other studies in Belize have shown reef systems falling into extreme decline when the sharks have been overfished, destroying an entire ecosystem.
Studies are already indicating that regional elimination of sharks can cause disastrous effects including the collapse of fisheries and the death of coral reefs. The downstream effects are frightening: the spike in grouper population (thanks to the elimination of sharks) resulted in a decimation of the parrotfish population, who could no longer perform their important role: keeping the coral algae-free and therefore reducing the oxygen quantities in our atmosphere.
Sharks are long-lived, slow growing and late to reach maturity and reproductive age.
This means they take a long time to recover from over-exploitation.
Shark culling occurs in both Queensland and NSW via shark nets and drumlines (baited hooks).
Hundreds of targeted sharks, many of them threatened species, are caught each year in each state.Live shark finning, the practice of cutting the fins from live sharks and dumping the body, is illegal in all jurisdictions in Australia, thanks largely to campaigning from the AMCS community. We are currently focusing our work on: Alternatives to shark culling already exist.Surf lifeguards and lifesavers monitor our popular beaches around Australia’s coast.Or that we could lose more oxygen than is produced by all the trees and jungles in the world combined if we lose our sharks. Two hundred and fifty million years ago, this planet suffered the largest mass extinction on record, and scientists believe this was caused in part by catastrophic changes in the ocean.Sharks play a keystone role ensuring our seas remain in a healthy equilibrium and do not reach that point again.A number of scientific studies have demonstrated that the depletion of sharks results in the loss of commercially important fish and shellfish species down the food chain, including key fisheries such as tuna that maintain the health of coral reefs.As important apex predators, sharks have shaped marine life in the oceans for over 450 million years and are essential to the health of our oceans, and ultimately to the survival of humankind.Innovative approaches have been developed, such as a ‘clever buoys’ and shark tagging and monitoring, where tagged sharks “tweet” their location as they swim past underwater detectors.We can use non lethal methods like these to help us avoid unnecessary shark attacks.Over 60 years in NSW alone, the shark nets and drumlines also caught and killed 15,135 other marine animals including turtles, whales, dolphins, rays, dugongs, and countless large and small sharks.Shark netting and baited drum lines are an outdated and archaic means of sharing our coastline with sharks.
