RESEARCH
Undersea
Explorer's frequent access to an easily monitored population
of Reef sharks at Osprey Reef, and Tiger Sharks at Raine
Island, gives us a unique opportunity for long term comprehensive
study which investigates growth rates, breeding times and
locations as well as behavioural patterns and movements.

A
key element is the identification of individual animals,
consistent monitoring of the population at monthly intervals,
and recording of growth characteristics on an annual basis.
Since this project began in June 1996 there have been 30
individuals identified with 10 sharks easily recognised
by external markings. We have also implanted 28 sharks with
microchip tags. 2003 has seen additional studies into the
depth movements of sharks. Our efforts have also included
lobbying to have Osprey Reef (and the shark population)
protected.
There
is very little known about the basic biology and ecology
of tropical sharks. Over recent years there has been an
increased concern over the status of shark stocks around
the world. The reproductive strategies and life history
of sharks make them extremely vulnerable to overfishing.
Undersea
Explorer has programs to research white tip sharks at Osprey
Reef, Tiger Shark (Far Northern GBR) and general shark behaviour
observation programs.
