‘Of Rocky Reefs, Headlands , and Rock Flatheads’

by David Muirhead

 

This living rock did indeed have a head, but not as flat as many of its mates. 

 

And what with the large and not very streamlined spiky eye and opercular bits, weird-looking  tube-like or noodle-like multicoloured dorsal fin spines and other appendages and adornments, coupled with the seemingly haphazard light and dark head body and fin markings manifesting as spots blotches lines and bands, at first glance I found it hard to decide whether I was looking at a very spiky and almost deformed or diseased flathead versus some sort of unusually low-profile gurnard or other member of the scorpionfish family.

Rock Flathead - Thysanophrys cirronasus

 

Where?: Carrickalinga Beach: the nice reef out from the elevated wooden access walkway by the toilet block, well-known as a good shore dive.

When?: recently.

 

Why?: have camera will dive.  (And to prove yet again that my ankle is no longer busted)

 

Conditions: fairly average with a surgy swell and viz of about 8 m at best but as little as 3 m close inshore.

 

I think it’s worth while writing this little snippet to direct fellow divers’ attention to yet another supposedly fairly common but in my experience seldom seen highly cryptic local critter.  This is an excellent larger example of the sort of fish you will only have much chance of noticing if you are having a careful look at everything on the bottom, especially amongst the more boring low-lying substrate lying between the more interesting ledges and larger rocky outcrops (consisting in this case of low profile rock, rubble, sand and scanty algae).

 

I’ve only seen this flathead species a few times in my diving memory, and this was the first dive where I had the luxury of unhurried close observation as well as being the first time I’ve been able to get photographs of a rock flathead Thysanophrys cirronasus.

 

Dorsal fin detail

 

The reference books indicate that this is really quite a small species as flatheads go, and is not surprisingly usually found in or near rocky areas such as inshore reefs, but I can tell you that of the flathead species I’ve seen here in South Australia the rock flathead is definitely the most appealing to the human eye because of its highly developed site-specific cryptic appearance.

 

Despite the limited visibility and surgy conditions making it hard to get good photographs my images still seem to convey what this fish is all about. If you don’t agree please look at the images showing detail of the spinous dorsal fin, quite fantastic really. Indeed if I could just indulge my poetic licence, as is my want, after one of two drinks, one can even see subtle nuances of anglerfish, weedfish, velvet fish and suchlike southern temperate marine masters of disguise!

 

Dear readers, yes I know that I again risk losing you if I continue, so enough said but for your own entertainment sake do please keep a lookout for this very colourful and ‘ugly-cute’ little flathead , representing as it also does yet another unique local fish endemic to southern Australia.

 

Is there anything like it amongst its tropical reef cousins?  Don’t know and don’t care.... as if you lot didn’t already know, I’m totally hooked till death us do part on our very own and very magical southern temperate marine biodiversity!

 

 

The P.V. Akuna Amphibious*

by Steve Reynolds

 

I first became interested in a riverboat called the Amphibious whilst I was researching the Decoy for my article titled “More On Former River Boats In SA Waters” (MLSSA Newsletter October 2006, No.337). The information that I have managed to gather about her since then is detailed below: -

In 1875, the Britannia Ironworks in Melbourne, Victoria built a 49-ton, 60’-long iron-hulled twin-screw steamer, which was to be called the Amphibious. She was intended for trading on both the River Murray and the Murrumbidgee River. Her design was ‘experimental’ in that the top halves of her propeller were above the water for times of low water in the rivers. She was launched in Victoria’s Yarra River before steaming from Melbourne to Goolwa in June 1876 for a trip upriver to Wagga Wagga on the Murrumbidgee River. That involved her negotiating the Murray Mouth. Going through the Murray Mouth was not uncommon back then, before the Goolwa barrages were built.

She became registered in Port Adelaide in 1877. She was acquired by Richard Fricker in 1904 and converted into a ketch. She was lengthened to 75’ and had her hull timbered over to apparently become a 40-ton composite vessel. Her engines were removed and masts were fitted to her for rigging as a ketch.

She later came under the joint ownership of Richard Fricker and Albert (aka ‘Skug’) Cutler*.

* (See my article titled “More On Former River Boats In SA Waters” (MLSSA Newsletter October 2006, No.337).

By 1956, motor engines were installed once more and she was fitted with twin-screws again. Two kerosene engines powered her. In 1959, Roy Bascombe bought her for use as an excursion vessel on the Port Adelaide River. He converted her into a showboat by enclosing the deck and fitting a dance floor. She began a regular programme of three-hour pleasure trips along the Port River to Outer Harbor in September 1959.

She continued as a showboat in this manner until she was replaced by the Lady Chelmsford in 1971. She later featured in movies such as Peter Weir's 1981 film “Gallipoli” and the TV mini-series “The River Kings”. Whilst laid up in the Port Adelaide Canal at some stage, she sank at her moorings and remained submerged for some months. When she was eventually raised, she was sold to cover the salvage costs. At some stage, a Mr R.Bromhead became her owner and returned her to the River Murray.

Dick and Wendy, the present owners of the Decoy, told me around 2006 that it was the Amphibious that towed the Decoy down river from Paringa (near Renmark to the Mannum Boat Haven, where she was to become the family home, in 1984.

In 1999, Peter Teakle became the new owner of the Amphibious and renamed her PV Akuna Amphibious after his Akuna Station (where she was located at that time) - ‘PV’ meaning ‘Paddle Vessel’, as opposed to ‘PS’ for ‘Paddle Steamer’.

 

Akuna Station is located on the River Murray, between Kingston-on-Murray and Waikerie. ‘Akuna’ is believed to be Aboriginal for ‘running water’. (‘Amphibious’, of course, means ‘living both on land and water’, etc...)

Akuna Station was established during the 19th century as a fording station for stock crossing the river. It was also a Cobb & Co. coach stop and postal depot.

The Akuna Amphibious is said to have participated in the “Mildura Celebrations” from 1st to 2nd September 2001. She was there with the Oscar W to help to ferry people from the smaller boat mooring area to the main area (and return). 

The Akuna Amphibious was also present on the Wentworth riverfront in July 2004 for the recommissioning ceremony of the Ruby following her restoration.

A Riverland tourism operator called Don Workman died at Christmas 2006 when his 1940s single-engine Auster J5 light plane hit powerlines and nose-dived into the ground moments after taking off in south-west Victoria. As the Akuna Station manager, he had often skippered the Akuna Amphibious. Mr Workman was the only occupant of the plane which he flew most days. It had been built in 1947 but was fully restored. Workman's funeral was held on the lawns overlooking the river and the cliffs alongside where the Akuna Amphibious was moored at the wharf. His coffin was then carried aboard the teak and redgum paddleboat, which then drifted downstream.

The Akuna Amphibious is now described as a 72-tonne displacement side-wheeler whose dimensions are said to be 78’ long, 16’ beam (35’ across her paddle boxes) and 2’6” draught (23.4m x 4.9m x 1.7m). She is now apparently powered by a rebuilt “120hp 6354 Perkins diesel engine into a Paragon marine gearbox into Cat D4 dozer diff. electronic clutches and brakes”.

 

Her accommodation is said to comprise of the Captain’s State-room and two guests’ bedrooms. She is completely fitted out with all the required luxuries, including private toilets and bathroom.

The Akuna Amphibious is said to be the second oldest paddleboat in Australia. She has featured on Channel 9’s “Postcards” program a couple of times. A couple of great photos of her can be seen at: http://www.smashn.com/index.html
