Areas of coral reef that are completely closed to fishing vessels are
significantly more effective at conserving sharks than areas in which shark
fishing is temporarily banned.
New research by scientists at James Cook University's School of Marine and
Tropical Biology, which has recently been published in the journal Current
Biology, says that an order of magnitude fewer sharks are found on fished
reefs compared to those where fishing is banned.
Managed no-entry zones (NEZ), which make up about 1% of the Great Barrier
Reef, had an order of magnitude more sharks than areas in which shark
fishing was allowed.
Harder to enforce no-take zones (NTZ), in which shark fishing is banned,
offered almost no protection to shark populations.
