Ahh the old crab pot theft.
In my usual boderline obsessive way I looked into this recently.
It is an offence under fish regs to 'interfere with commercial operation / apparatus' but not rec. So it is a police matter, unless you can accurately describe what was stolen [how many crabs, what size] you can't really lodge a stolen goods report.
So what can you do to stop your gear being stolen?
A Keep your eye on them. Prefferebly through the telescopic sight of a High powered rifle. So you are ready when the thieves arrive.
B Read the regs very closely...
Fisheries Regulation 1995. Schedule 8 Part 1 Section 5 Marking of fishing apparatus
(1) A crab pot, collapsible trap, dilly or inverted dilly (crab apparatus) used to take crabs must have a tag with the owner’s surname and address written on it.
(2) Also, if the crab apparatus is not fixed to something while it is in use, the apparatus must have a light coloured float attached to it.
(3) The float must be at least 15 cm in any dimension and have the owner’s name written on it.
Very broad word that "something" I querried it and apparantly a meter of rope and a snapper lead counts as something. So:
A: If you have a GPS and can ping the location.
B: You can throw a grapple.
You will never have another pot stolen.
Couple of issues tho.
A crap pot is a very efficient killing machine, and the all-synthetic materials mean that it just goes on killing for years. Down the pin once a mate and I were sitting peacefully fishing when a crap pot float bobs past. I pulled it in and in the pot was three good sized cod skeletons & two muddie carapaces. Obviously it had been lost some months earlier and the cod had gone in after the bait, the crabs after the dead cod on & on & on. I reckon it should be a requirement that one panel in the wall of the pot should be made of a natural fibre so if the gear is lost eventually it will stop killing.
Also Floats are the Number one way a fisho can check how many pots are being used, a line of 10 floats all with 'Smith' on them will probably lead to Mr. Smith beeing asked how many people are on his boat. No floats mean that the fishos can't tell, unless they fluke upon mr Smith with all ten on his boat.
So keep this to us good guys.
