It’s been a good story for newspapers over the years. Shark attacks. Far more of them were occurring in the 1930’s – obviously when the Australian populated coast had better stocks of seafood to attract and feed the predators.
Looking at a small sample of shark attacks in newspaper files indicates how these tragedies gave been forgotten. There has been, seemingly hundreds of shark attacks around our coast – more than what is commonly stated.
Here is a sample from the archives from pages 10 and 11 – it could form a good university study in changing journalism standards over the years.

Manta rays have a couple of bites to their wing, Green turtles are food for tigers, as for Leopard sharks – probably not exciting food. Grey nurse would be eaten by anything larger than themselves. Killer whales would make a feast of their liver.
All pictures from the same day at Point Lookout, Queensland. At one time my favorite spot on the east coast – even better than Seal Rocks, NSW.

Cooked with special healthier chicken for many hours. Is it cruel? Is boiling a live lobster any less cruel?
Who is making a profit from promoting the story that sharks are a threatened species in the ocean? The information is now ten years old in most examples especially the video of a live shark being finned then dumped from a long line fishing vessel under power.
Overfishing of fin fish around the world is leading to an imbalance with sharks outnumbering fish of equal size. Sharks are not as endangered as fish. Eat more shark? It’s already happening. Surimi is processed shark sold as crab sticks, fake lobster and fish balls.
The hazard of eating large shark products is toxic heavy metals in their body.
As for fining live sharks? Pointless as the body must now accompany the fins to market.
There’s a lot of out-of-date information circulating. Briefly:
1. Fishermen prefer to catch marlin, swordfish, tuna – high value products.
2. Sharks take the baits intended for tuna, marlin, on lines many kilometers long.
3. Sharks, unable to swim, then drown. Unable to swim, they drown, dead in 95% of cases.
4. So, what to do with the dead sharks? Throw them away? Process them for $2-3 kilo?
5. Many (or most) countries, by law, now make fishermen bring whole sharks home, fins attached.
6. Shark meat is processed into fake fish products, crab sticks, fish fingers etc.
7. Shark fins are just a bonus, (as compared with a large tuna) crazy to wast them.
8. A new bait is being trialed, a bait that tuna take yet is distasteful to sharks. It’s expensive.
9. Fishermen see many sharks offshore and sincerely believe there is no detrimental shortage.
10. There is a decline in all other fin fish, world-wide this is accelerating.
11. Shark diving companies would have you believe all of the above shark info is untrue.
12. Same applies to self-promoting marine ‘experts’. Easy to be interviewed speaking ‘doom and gloom’ info.
13. Bottom line at Taipei Shark Conference 2002 “We (scientists) should speak more often with fishermen to help with our research.
However, imitation crab is probably made from stingrays.

Conversion rate for $1000 New Taiwan Dollars is about US $33.oo HOWEVER the weight may be not in kilo’s.
A common weight used is 600 grams, I think!

(Bottom left) Sydney tabloid newspaper Telegraph regularly features marine stories. Tues 25 June was a 2.47 meter male bull shark tagged and released at Manly that entered Sydney Harbor (Port Jackson) and apparently became ‘lost’, moving throughout the harbor.
1. Bulk of the sharks time was spent west of Sydney Harbour bridge.
2. On a single day it traveled 55 km.
3. During 14 days it traveled 295 km with three days unaccounted for.
4. 230km was traveled during darkness hours.
5. Another 55 sharks have been tagged for tracking by Dept.of Primary Industries. Sydney harbor was a priority after recent near-fatal attack on a navy diver.
6.There are 38 listening ‘posts’ in Sydney harbor with another 200 along the coast to track the tagged sharks.

There was a fatal shark attack at Balmoral in the early 1960’s on a spear fisherman.
