Shark conservation is vital. There are around 350 species of shark, ranging from the size of a human finger to the size of a large bus, such as the gentle whale shark.
Sharks are a slow growing fish that produce few young, yet it has been estimated that 100 million sharks are been killed by humans each year in commercial, recreational or illegal hunting.
The future of marine life depends on sharks. As predators, sharks keep fish populations in balance and cull out the sick and injured. Keeping sharks in captivity is not easy, as they require space, familiar natural surroundings and appropriate temperatures. Species that cope well in tanks and that can be bred and released are the grey nurse, the wobbegong, the Port Jackson and the Zebra shark. But the oceanic sharks such as the Great White, the tiger and Blue Shark, don’t fair well in captivity. They soon die.
If we continue to interrupt their habitat with excessive fishing, shark netting along beaches, and noise and pollution from shipping highways, they will soon die in their natural world.
Sharks have no malice toward us. They just have a response to food. People must respect their place in the ocean and accept the risks when entering their domain.
We owe this species its continued survival.
