We really don’t know anything about the population size or stock structure of tiger sharks occurring in NSW waters, or much about their movement. We do know that relatively large specimens (around 200kg plus) are fairly common off central NSW during summer months, as they are relatively easily caught by game fishers during this time of year. In fact, despite tiger sharks being found throughout the world, all but one of the world angling records for the species have been caught along a relatively small stretch of NSW coastline between Port Macquarie and Ulladulla. This may indicate the importance of NSW waters for adult tiger sharks, or alternatively, it could suggest higher fishing pressure for this species in this area. Either way, it is something we probably need to get a better handle on.
A project funded through New South Wale’s Recreational Fishing Trust is helping to fill in the blanks regarding the life history of one of the biggest and most enigmatic species encountered by recreational gamefishers: the Tiger shark (Galeocerdo cuvier). These blunt-nosed pinnacles of the marine foodweb are believed to live for up to 50 years of age, reach up to 20-25 feet in length, and nearly 900kg in weight.
Their massive size and reputation for chewing on the occasional human have ensured their place in folklore, however it may surprise some to learn that very little is really known about tiger sharks from Australian waters.
