Welcome to Shark Watch, a tracking site where you can follow sharks that SEA LIFE Australia/NZ have assisted with tagging. Shark Watch was created as an epicentre of shark tracking for all SEA LIFE sites in Australia and New Zealand.
We know so little about these fascinating creatures. Yet one thing we do know is that they are in a downward spiral. Finning for shark fin soup, getting caught as bycatch in commercial fishing gear and shark nets are driving many species of shark to the brink of extinction. Once an apex predator is removed from a marine system, many prey species proliferate. Predictions of oceans full of jellyfish and squid could be the norm if we continue to unsustainable fish out our sharks.
By raising awareness of the plight of our sharks we can help conserve remaining populations to ensure that this group of animals that has existed for hundreds of millions of years, continues to do so.
The tracking system simply connects the most recent data points and draws a line even though the shark did not travel over land.
No, the tag transmits all the data points (from each surfacing throughout the day) to a satellite once per day which is then sent to a collection point once per week. We receive this data weekly and then update each shark’s journey.
No, as with the over land scenario the tracking system draws a line between the last data points transmitted. The shark is likely to have meandered quite a lot in between.
Sirtrack Fastloc™ tags are fast acquisition GPS technology designed for marine animals which only surface briefly. Raw locations are then relayed back to the researcher via the Argos satellite system.
The tags cost approximately AUD $3,500 each. Satellite time costs around 100 Euro per month. Tracking a shark for the life of the tag (from 12 to 18 months) can cost in excess of AUD $5,000.
The life of a satellite tag is constrained by its battery life which is typically from 12 to 18 months. Sometimes tags can be lost based on animals dislodging it when entering or exiting crevices or become deployed if the animal gets caught in fishing gear or shark nets.
Male sharks have two external protrusions on their underside called claspers which are easily and quickly identified. Female sharks don't have claspers.
Over 350 species of shark have been identified but there are likely to be more waiting to be identified.
Many species are listed as ‘endangered’ or ‘critically endangered’ on the IUCN Red List of Endangered Species.
