Equalisation when diving

After conquering a few mental fears equalisation is normally the biggest obstacle that most spearfishers will encounter.

The reason we need to equalise is because it bloody hurts you if you don’t. How’s that for a good enough reason?

Seriously, hydrostatic pressure (10m ocean depth is equivalent to 1 mile high in the sky. We take approximately 10 seconds to arrive at 10m).  That’s why we need to equalise.  As you descend the water pressure increases hence the pressure increases inside your ear canal, hurting your tympanic membrane (ear drum) – you have to “equalise” this outside pressure by matching it with air pressure that you have inside you. Equalising maintains pressure balance between the middle ear space, the rest of the body and surrounding water.  The Eustachian tube comes into play here, this tube runs from the back of your nose to the air space of the middle ear. The tube is generally collapsed, opening when the “clearing” (equalising) process eventuates. When you experience the “crackle, pop” sounds you are equalising, relieving the pressure on the Tympanic membrane and sinus cavities. Correct technique and equalising before you experience discomfort is the key to comfortable spearfishing, and ensuring there is no chronic damage to your eardrums.

Submarine Spearsman – The Queenslander – 1 July 1937

Submarine Spearsman

1937       1 July 1937

The possibility of spearing fish under water is queried by “H.V. In doing so, he challenges the traditional manner of fishing employed by the almost amphibian Torres Straits Island natives. Armed with long spears, Binghi in these parts ventures down several fathoms in search of the finny quarry, and disappears from sight for minutes on end to emerge with a wriggling fish or crayfish impaled on the spear point.

In this submarine venture Binghi wears a pair of “swim glasses” or water tight goggles, which protects his eyes from salt water irritation and permit some yards of under sea vision.

Binghi’s spear thrusts do not have to depend on chance for a success, as they are the result of a perfectly developed marksmanship. So sure of his prowess is the native that on occasions he is able to transfix the brain box of the fish so that it dies instantly, instead of stampeding the rest of the fishy school by its death flurry on the spear point.

Spear Fishing – Cairns Post – 1940

Spear Fishing

1940       13 May

Spear Fishing is rapidly becoming a leading sport amongst the youth of Innisfail. The spear employed, unlike the four-pointed spear used by the aborigines, consists of a length of iron with a sharp barb at one end. The swimmers, who wear water glasses, enters the water and submerges to await the fish. When a fish comes near the end of the spear the swimmer makes a jab, and if successful, immediately raises the point to prevent the fish from escaping.

Angles on Angling

Angles on Angling

1947       9th May

24 years old Alf Rowen, who conducts a bootmaking establishment in Crown Street Wollongong, has a natty fish catching device.

None of this old-fashioned sinker and line business for Alf – he has a “sear-gun” that fires a 4ft. 6in. stainless steel shaft UNDERWATER!

He dons goggles and a lead – weighted belt (to keep him steady on the sea floor), shoulders his “spear-gun,” takes a deep breath and dives into the depths.

Usually, Alf hides himself under a ledge, or in a hole, and lays in wait for some large, unsuspecting fish.

He claims he never worries about the small ones and during Easter, at Sussex Inlet, the average weight of 80 fish caught was 1 3/4 to 2lbs.

Alf will be ‘shooting’ them on Sunday morning between eight and eleven o’clock, just off the Wollongong Continental Baths.

One that didn’t get away – Record Black Bream

ONE THAT DIDN’T GET AWAY

1969 13 July

Spear fisherman Michael Bray, of Johnson Street, Peakhurst, holds a 23in long black bream which he caught in Sydney Harbour off Shark Island.

Michael arrived for the Metropolitan Skin Divers’ Club  presentations with the catch last night.

Record Black Bream“Now they will have to believe me” he said, nursing the deep-frozen bream weighing 8lb 1oz (3.657kg) and with a girth of 20 inches.

He saw the fish while swimming with a friend, Mr Mervyn Sheehan, of Sans Souci, on Friday.

“We both fired together: my spear hit him in the side – my friend’s spear missed.”

Michael said he used a rubber-powered gun for the catch.

Michael, a sculpture student at the East Sydney Technical College belongs to the St. George Skin Divers’ Club.

He said he would eat all of the fish himself tomorrow. “I’m very fond of fish.” He said.

The publisher of “Anglers Digest” said last night that Mr Bray’s catch was almost certainly a record for a speared fish.

He said an 8lb 4oz black bream had been caught with a line at Swansea in 1967, but previously spearfishermen had not caught one anywhere near that weight.

Results of an Unbiased Fishing Survey – 1966

1966 September

RESULTS of an UNBIASED FISHING SURVEY

An article by a very old friend of mine, Bill Barada, is based on the findings of a survey on the “Sport Fish Catch and Effort” made by the Resources Agency of the Department of Fish and Game of California. This comprehensive report by Daniel J. Miller and Daniel Gotshall, took four years to compile and concerned nineteen employees of the Department directly assigned to field duties on the project, apart from scores of persons acting in honorary capacities. This 135 page report, which I have read carefully, completely dispels any theory that skindivers could be held responsible for any overall depletion of fish stocks in the U.S.A. and there is nothing to suggest it would be otherwise in Australia.

Of all sport fishermen, anglers fishing from piers, jetties, etc., captured 1,034,000 fish representing 32.1% of the total sport catch. Shore fishermen, angling from beach, rock and estuary, contributed 31.9% of the total, while anglers operating from charter boats caught 24.9% and from small craft 10.5%. Skindivers or spearfishing, with all its so called efficiency, accounted for 0.7% of the total sports fish taken.

Spearfishing Competitions – 1976

SPEARFISHING COMPETITIONS

Dear Sir

I am the unrepentant hunter of fish, and manufacture equipment to hunt fish. I think most groups of spearfishermen ensure that their catch is eaten, that ecological principles are observed, and their sport is correctly enjoyed. Of prime importance is that the young are maturely guided – there is no generation gap between underwater buddies… (Let’s use the Australian term – mates).

Spearfishing clubs have to be commended for their work in education. Such indoctrination can only be done through clubs, and if over restrictive measures are taken they will not be followed, but broken in a regrettable manner.

The sport of spearfishing has saved many lives. Men have learned to obtain food and in emergency have learned to cope with tempestuous conditions to save their personal lives and the lives of others – in many cases to cooperate with authorities to retrieve bodies. There are quite a number of awards for bravery given to the risk of life.

The sport demands the utmost physical challenge and it has particular appeal to the adventurous young who are willing to be guided in balanced conservation by the leaders of their sport – but without the willing guidance of such sportsmen they would be rebellious!

When one considers the millions of tons of fish taken commercially, and compare this factor to the catch of spearfishermen in the occasional shallows which allows their sport, it seems the conservationists are using the sport of spearfishing as a target for the promotion of that cause, or their personal advocacy – rather than to achieve effective measures of fish preservation.

Yours faithfully

An evening discussion of Spear Fishing Ethics & Sustainability

Ian - Fisheries
Ian – Fisheries

The origin of this seminar was brought about due to the World Wide Web continually being under estimated by spear fishermen , that’s us!

Where many praise a Billfish capture; a large fish say a Mulloway that is happened upon while spearing Bream for tea; catching your bag limit of just legal (maximum) lobsters, there are the people who will taunt you for doing this. There are several errors of judgement we can make as a hunter and gatherer when using social media. Continue reading An evening discussion of Spear Fishing Ethics & Sustainability

Alliman Shield 2015 – 12th April – Little Manly

6:45am one week after daylight saving ended dawned dark and grey at Little Manly cove as the boats gathered on the beach as the ring was put up and the tables set up for the weigh in later in the day.
Alliman Shield 2015 - Little Manly 2
Forty three divers signed up for the competition including that old stalwart Trippey from the Dolphins who was seen shaking out mothballs out of his dive gear. There was a lot of talk and catching up and it was good to see a new breed of young guns from the North Shore Seahawks that a forming a good team.

Alliman Shield 2015 - Little ManlyThe safety talk was conducted and everyone made their way from the reserve to the boats and a few minutes before 8am the boats made their way out slowly to the gathering point outside the cove ready for the flag start from Emanuel’s big R.I.B.

The flag was waved and the boats made their way in all directions some up the harbour and the rest out to sea.

The conditions were quite ordinary with a strong Southerly wind blowing and a nasty sloppy chop making things uncomfortable. Coupled with this was an ordinary 6m to 8m cloudy visibility with a lot of particles throughout the water. Nevertheless the conditions were still very spear able and the fish that came into the weigh in was proof of this. Continue reading Alliman Shield 2015 – 12th April – Little Manly
