Definitions

  • the present invention relates to aquatic animals, particularly sharks; to tags to identify and locate such animals; and a shark alarm system for beaches and like localities where humans swim.
  • the genesis of the present invention is a desire to provide apparatus and a system which goes some way towards achieving the abovementioned goal.
  • an aquatic predator snagging apparatus comprising a GPS transmitter having a bait including an engagement means and being connected by a frangible link to a deployable submersible base.
  • an aquatic animal tracking tag comprising an animal attachment means, an electronic transmitter or transponder device, a rechargeable battery connected to said device to power said device, and a hydroelectric generator means connected to said battery to re-charge said battery and energised by motion of said animal though said water.
  • a shark attack warning system comprising at least one shark having a GPS transmitter tag attached thereto, a GPS tracking device to track the current position of the, or each, said tag attached shark and associated with a computer, a position comparator means associated with said computer to compare the known location of beaches and like localities to be protected from shark attack with the location(s) of said shark(s), and alarm initiation means associated with said comparator means to initiate an alarm in the event that any one or more of said sharks comes within a predetermined distance of a said locality.
  • a method of temporarily snagging aquatic predators is also disclosed.
  • a method of removing the snag and attaching a permanent tag is also disclosed.
  • Fig. 1 is a schematic side elevation of a preferred embodiment of the snagging apparatus of the present invention
  • Fig. 2 is a longitudinal sectional view through the preferred tag of the present invention
  • Fig. 3 is a plan view of a beach showing the deployment of the snagging apparatus of Fig. 1;
  • Figs. 4 to 6 each illustrates a corresponding sequential step in the method of removal of the snag and attachment of the permanent tag
  • Fig. 7 illustrates the operation of the shark alarm system of the preferred embodiment
  • Fig. 8 is a schematic representation of the shark attack alarm system of the preferred embodiment.
  • the apparatus used to snag sharks takes the form of a base buoy 1 having an anchor cable 2 and an anchor 3.
  • a snag buoy 5 is attached to the anchor cable 2 by means of a frangible flexible link 6.
  • a rubber or plastics imitation seal forms a decoy or bait 8 which conceals a hook 9 which is connected to the snag buoy 5 by means of a tether 10.
  • the tether 10 is connected to a weight 11 which, like the anchor 3, sits on the sea floor 12, preferably adjacent a beach.
  • Secured to the tether 10 is a camera 13 and an acoustic device 14 or dolphin pinger.
  • the acoustic device is intended to deter dolphins.
  • the acoustic device 14 is preferably battery powered.
  • a data cable 16 interconnects the camera 13 and the snag buoy 5 and a power cable 17 interconnects the snag buoy 5, the camera 13, and the decoy 8.
  • the decoy 8 is provided with a 12V vibrator (not illustrated) which imparts a pseudo-struggling motion to the decoy 8.
  • the power for this activity is transmitted via the power cable 17 from 12V batteries in the snag buoy 5.
  • the snag buoy 5 is also equipped with a GPS transmitter (known per se) including an antenna 19, and submerge detectors 20.
  • the decoy or bait 8 attracts passing sharks which, if sufficiently large to be a potential source of risk to human bathers, are also sufficiently large to be snagged by the hook 9 and generate a substantial longitudinal tension within the tether 10.
  • This longitudinal tension is able to be measured by a tensiometer (not illustrated) located within the buoy 5 which therefore records an estimate of the weight of the shark and, in addition, activates the camera 13 to thereby record a photograph of the shark.
  • the photographic data is transmitted by the data cable 16 to the electronics contained within the snag buoy 5.
  • the photographic data, weight estimate, time the bait was taken, etc are all recorded by the buoy 5.
  • the weight of the shark breaks the frangible link 6 thereby enabling the snag buoy 5 to henceforth travel with the shark.
  • the submerge sensor detectors 20 (which preferably include a 30 second delay mechanism to screen false detections) enable the snag buoy 5 to determine whether or not it is at the surface. In this way transmissions via the antenna 19 to the well known overhead GPS satellites are limited only to times when the snag buoy 5 is at, or near, the surface. This therefore conserves battery power.
  • the snag buoy 5 is intended to be recovered from the shark and a permanent tag 22 attached to the shark in place thereof.
  • the preferred form of the tag 22 is illustrated in Fig. 2 and takes the form of a substantially cylindrical carbon fibre reinforced housing 23 having a nose cap 24 which is connected by a stainless steel cable 25 to a barbed anchor 26 intended to be inserted into the dorsal fin of the shark.
  • a depth sensor 30 is provided to deactivate the transmission of any GPS signal when the housing 23 is not adjacent the surface.
  • the abovementioned electronics are powered by means two 12V batteries 33 which have a ten year operating life and which are recharged by means of a 12V hydroelectric generator 34 which has an impeller 35 positioned between a water inlet 36 and a water outlet 37 arranged in coaxial fashion at the tail 38 of the housing 23.
  • the water inlet 36 is fashioned in the form of a cylindrical coaxial shroud and thus directs water (forced therein by the motion of the tag 22 through the water) past the impeller 35 thereby generating electric current and prolonging the life of the batteries and electronics to at least 10 years.
  • a sequence of base buoys 1 each with their attached snag buoy 5 are located on the sea floor adjacent a beach 41 having a surf club 42 or like building housing Life Savers, Life Guards or the like.
  • a shark 44 has taken a decoy or bait 8 and thereby detached the corresponding snag buoy 5.
  • the shark 44 moves the snag buoy 5 as the shark travels through the water.
  • the movement of the location indicated by the GPS signal transmitted by the snag buoy 5 indicates that the snag buoy 5 has been taken by the shark 44.
  • the hydroelectric generator 34 in its tag 22 recharges the batteries 33 enabling the shark's position to be transmitted from time to time to the GPS satellite and thereby tracked at a convenient ground station.
  • the position of tagged sharks is compared with the position of localities to be protected such as the southern end of the beach indicated in Figs. 3 and 7.
  • the snagging system enables sharks to be tagged in due course with a tag 22 but does not harm animals such as dolphins and turtles which have mouth parts which are of an insufficient size to bite on the decoy or bait 8 and thus become hooked. Furthermore, there are some species of sharks such as the grey nurse shark or the white pointer shark which are endangered or protected species. It is therefore desirable to minimise the deaths of such animals in shark nets which inevitably are species indifferent.
  • a computer 50 having a screen 51 and a keyboard 52.
  • the computer 50 also has a built in (or attachable) GPS receiver Rx, the output of which is connected to a memory M. Also connected to the memory M is a comparator C, the output of which is connected with an alarm initiator AI.
  • An alarm 60 is connected to the alarm initiator AI and is visible from, and within hearing distance of, the beach 41.
  • the shark 44 having the tag 22 swims near the beach 41 and the tag 22 sends the co-ordinates (latitude and longitude) of the shark's location to an overhead GPS satellite 59 which re-transmits this information to the GPS receiver Rx.
  • the comparator C compares the shark's location to the location of the surf club. If the shark 44 is within a predetermined distance of the surf club 42, then the comparator C triggers the alarm initiator AI to in turn activate the (preferably both audible and visible) alarm 60. This enables bathers (not illustrated) to leave the water until the shark 44 departs.
  • a computer 50 can be located at each beach 41 where a shark alarm system is desired.
  • a single computer in a central location can provide (for example by telecommunications) specific alarms to specific beaches.
