Improvements to minimize ‘collateral damage’ could be costly yet feasible to diffuse anger promoted by environmental agencies. An obvious example might be:
1. Better positioning (where nets are placed deeper and touching the sand,
2. Leaving sufficient above-net space for surface animals to pass above);
3. Divers inspecting nets every few hours to release non sharks;
4. Tagging and releasing some sharks except the meshing net principle is, trapped, struggling or dead sharks warn other sharks to stay from danger (they are not stupid).

Meanwhile, to combat phantom pains (itches and aches etc.) in the lost lower half of a leg, Henri learned self hypnosis soon after his ‘accident’ as he called the shark attack.
The effect was, he could explain how the shark bit his leg off and almost turn the incident into humor, sometimes.
So convincing was his attitude to living normal life, without thinking I once criticized him for parking in a disabled parking space.
Mike Perry checks our boat, Amity Point, Queensland
We three rented a cabin where, at high tide, the sea water was under the floor. That cabin and many others have since disappeared as the western coast of this big sandy island slowly washes away.
The Australian mainland is seen in the distance, across Moreton Bay. To the south out of sight is The Gold Coast – in the opposite direction is Queensland’s capital city, Brisbane.
Two years ago bull shark(s) attacked and killed a swimmer just 50 meters from where Mike is standing.
Our shark diving was around the corner and offshore at a small rocky island 3 km from the holiday village of Point Lookout.
Occasional large tiger sharks are a possibility, attracted by the availability of stingrays and a few manta rays.

1. Sharks love the color red. 2. Sharks are said to be attracted to dogs 3. It’s a mistake to bump into a shark with a boat – especially when following one like the above, at any speed.
BEN CROPP and I assumed it was a tiger shark by the actions it displayed.
Could it have been a cranky Lemon shark – not an uncommon species at Batt Reef, and far out-numbered by the Tigers?
John D. Stevens (CSIRO) when asked for a shark ID, replied (in part): “It’s not a tiger shark, species unidentifiable”.
The confusion came after we saw numerous tiger sharks on the reef shallows earlier the same morning, attracted by – possibly – a harpooned dugong, sea turtle, or stingray – something large enough when injured to provided a stimulus attraction.
These were big sharks, 2.5 meters and upwards, with a single four meter monster seen the next day.
This seemed unusual for so many in a small area.
Batt Reef is a large and mostly sandy and shallow running some ten nautical miles in length, located off Port Douglas, Queensland. It is not a destination for tourist visitors. Quite a private place.

(Above illustration of shark teeth).From the 1950s when Grey Nurse sharks were still considered “Man Eaters”. That belief changed when the first underwater cinematographers began filming them in 1961. It took a few years for the new information to circulate in the pre-digital era.
When did white sharks begin jumping into the air after prey? It’s a recent occurrence – according to experts.

(Translation from French follows):
How CITES does it work?
There are three appendices to CITES offering varying degrees of protection for the species listed in the Convention. The application is usually done by customs officers or the national police, and all parties are bound by the treaty to adopt implementing CITES documents.
Appendix I or Appendix:
Species listed in Appendix I are threatened with extinction and the international trade in these species or their products is prohibited. Trade for non-commercial purposes is permitted only in exceptional cases. Approximately 600 animal species and 300 plant species are listed in Appendix I.
Annex or Appendix II:
Species listed in Appendix II are not threatened with extinction, but may become so unless their populations continue to decline, and if the trade goes so unbearable. Appendix II still allows international trade, but it is Notregulated, which gives a chance to recover depleted through a rigorous system that only allows legal and sustainable trade species.
For example, three sharks benefit from registration currently Appendix II: the great white shark, basking shark and the whale shark.
The countries agreed that these species are listed in Annex II because these sharks undergo a sharp decline in their populations.
At the 16th Conference of the Parties, a proposal will be voted for hammerhead sharks, oceanic sharks, porbeagle sharks and manta rays have the registration in Annex II.
Annex or Appendix III:
This appendix includes the species listed by the various countries that regulate trade among themselves and need assistance from the international community to prevent the illegal and unsustainable exploitation. It requires that all countries that export a species from Appendix III to ensure that these species have been legally obtained.
About 270 animal species and 30 plant species are listed in Appendix III.
Fishing has significantly depleted populations of sharks and rays in the last 60 years …
We must do everything we can to on the occasion of the 16th Conference of Parties of 3 to 14 March 2013, France The use of any part of its power to vote and use its influence to enroll in Appendix II, 3 species of sharks, porbeagle sharks, hammerhead sharks, oceanic sharks and sting rays.
