Description
Dec 1996
Will sharks be the next endangered species? Research is underway to rehabilitate the killer fish. SA's unique Shark Institute exists to protect humans from shark attacks. Every morning it sends a team of researchers up the Natal Coast to check on 400 nets shielding the most popular beaches. They untangle sharks, dolphins and sting rays trapped in the nets and repair any gaping holes. Many creatures, however, die before they can be rescued. This has prompted research into protection which does not kill sharks - electromagnetic waves. The director of the Natal Sharks board explains how divers use magnetic waves to deter sharks with small electric shocks. This could be further exploited for the use of swimmers. Dead sharks caught in the nets are taken back to the Institute where great slabs of bleeding flesh are sawn off for examination. One Austrian scientist reveals her fascination with the shark and her aim to find out how long they live. The Great White enjoys official protection in South African waters and research into this particular species is carried out through a tagging system.
