After The Encounter
Part 7 (Final)
By Steve Reynolds
My own program for celebrating Encounter 2002, apart from the various visits already mentioned, included climbing to the top of the Bluff at Victor Harbor to re-visit the plaque placed there in 1902 and soak up the atmosphere of the location whilst gazing out across the Southern Ocean. I also visited the statue of Matthew Flinders in North Terrace, Adelaide and a plaque at Port Wakefield. I saw an Encounter display at the Victor Harbor Tourist Information Centre and another one at Cleland Wildlife Park.
I have collected many pamphlets promoting Encounter 2002 events. One of them featured David Muirhead’s famous male Leafy Seadragon with eggs.
National Parks and Wildlife SA released an SA National Parks 2002 calendar in October 2001. This calendar celebrated the expeditions of Flinders and Baudin and it featured photographs of locations in SA visited by the two explorers. A few of David Muirhead’s photos from our Photo Index were included in the calendar.
All events covered?
Well, I have tried to cover all of the events that occurred in connection with Encounter 2002. There is no doubt though that some details have been left out. Hopefully, these missing details are just minor ones.
On November 8th 2002 "Encounter 2002" was awarded for being the year’s best "Significant festival & event" in the Yellow Pages 2002 SA Tourism Awards. At about the same time "Encounter 2002" was also recognised in the SA Great 2002 Regional Awards. It took out the Yorke Peninsula "Tourism Award". On Friday 21st February 2003 "Encounter 2002" was also rewarded in the National Tourism Awards when it picked up the award for the Significant Festivals & Events.
My congratulations to the organisers of Encounter 2002 which certainly was a great and successful celebration. The sight of the four tall ships was a great spectacle and to experience sailing on one of them would have been magnificent.
My thanks to everyone who participated in Encounter 2002, especially Anthony Brown and John Ford. Thanks to the SA Maritime Museum who were a great help to me and thanks also to The Advertiser for their extensive coverage of Encounter events and relevant history. Thanks also to both David Offord and Philip Hall for all their assistance and guidance.
Many thanks in particular to Evan John whose aerial photos of the tall ships at Granite Island, Victor Harbor were the inspiration for this article.

Rainbow Trout Really Do Feel Pain, Study Says
©Telegraph Group Ltd 2003
Evidence that fish do indeed feel pain is published today, a finding that will reopen hostilities that have raged for decades between anglers and animal rights activists.
Earlier this year, an American study seemed to let anglers off the hook: Prof James Rose of the University of Wyoming concluded in the journal Reviews in Fisheries Science that awareness of pain requires consciousness, which fish do not possess.
Now a study of rainbow trout suggests that they not only possess the equipment to feel pain, but react in a way consistent with suffering.
This is the the first conclusive evidence indicating pain perception in bony fish such as trout, salmon, cod and haddock, according to one of the authors, Dr Lynne Sneddon, who led the research at the Roslin Institute, near Edinburgh, and is now working in Liverpool.
"The study shows that the trout not only possesses nerves that can detect pain but also shows the kind of behavioural changes that would be associated with discomfort and pain in ‘higher animals’," said Dr Penny Hawkins, senior scientific officer of the RSPCA.
"All vertebrates should be given the benefit of the doubt and assumed to be capable of suffering."
Not everyone is convinced. Rodney Coldron of the National Federation of Anglers said yesterday: "We believe the Prof Rose study went into more depth and supports our view that fish do not feel pain."
Prof Rose told The Telegraph that the study "in no way justifies a conclusion that these fish have a capacity for the conscious experience of pain", attacking it as "anthropomorphic speculation".
The new findings are published by Dr Sneddon in Proceedings B, a journal published by the Royal Society. The work, also at the University of Edinburgh, was funded by the Biotechology and Biology Research Council.
Based on her findings, Dr Sneddon said yesterday that she had no problem with anyone who caught and quickly killed a fish for eating. But she drew the line at catching fish and throwing them back, which could cause suffering. "Some studies have shown high mortality after angling."
Her study, undertaken with Dr Victoria Braithwaite and Dr Michael Gentle, found that rainbow trout have nociceptors - nerve receptors that respond preferentially to tissue damaging stimuli. "We found 58 receptors located on the face and head of the rainbow trout," said Dr Sneddon.
The 18 "polymodal nociceptors", which responded to all potentially painful stimuli in the trout, were the first to be found in fish and had similar properties to those in humans, said Dr Sneddon.
Fish Do Feel Pain
I now feel a little vindicated since the announcement of new findings that fish do feel pain. Back in 1988, when I was our newsletter Editor, our July Newsletter (No.132) included the two articles "Fish Have Feelings" and "Fish Feel Pain". I had written the first article and the other was written by the Animal Liberation group. The following month our newsletter (August 1988, No.133) included a letter to the Editor from Geoff Mower on the subject and my response. I agreed at the time that Geoff had "quite rightly shot all of my suggestions down in flames". Although I don’t yet know the details of the new findings concerning fish pain, it is nice to know that there is still some belief that fish do in fact feel pain.
Applying Pain Theory In Fish Spine Envenomation
By David Muirhead
Part 4 (Final)
Two questions are posed. Has hot water immersion been trialled for above-water envenomations, such as arachnids, hymenoptera and arthropods? Some of these toxins are heat- stable so a demonstrable efficacy would challenge the role of heat-lability as already discussed. Interestingly, although application of hot packs to jellyfish stings has been found to have only mild analgesic effect, immersion of the affected part in hot water has been found to be very effective.6
Secondly, would hot-water immersion of the contralateral limb also be effective in marine fish spine envenomations, or even an upper limb immersion where the lower limb is envenomed, or vice versa?
In conclusion, an extensive literature search has failed to find evidence supporting the denaturation theory. Further research is needed to investigate the mechanism(s) underlying pain relief by hot water immersion of the affected limb following fish spine envenomation. The author hypothesises that modern pain theory provides a better explanation than heat denaturation of toxins.

MARINE WILDLIFE NEWS
Reports of marine wildlife from all around the British Isles, with pollution incidents and conservation initiatives as they affect the flora and fauna of the NE Atlantic Ocean. Full details of these reports and their authors can be found on the BMLSS webpage.
19 April 2003
The discovery of a Giant Goby, Gobius cobitis, found in a rockpool above the half tide mark at Les Ecrehous, Jersey, was a notable discovery. This goby is a protected species under the Wildlife and Countryside Act Schedule 5. It has always been known from the shores of Jersey but it is virtually unknown on the northern English Channel coasts with occasional records from Cornwall only. As it name indicates this goby is a ‘giant’ amongst the Gobiidae, a family of small fishes. The Giant Goby attains lengths of up to 25 cm.
15 April 2003
The Strawberry Beadlet Anemone, Actinia fragacea, has been observed discharging eggs in an aquarium. This method of reproduction has been suspected but there have been no observations in print before.

British Seahorse Sightings
When I first read the paragraph about the seahorse capture in "Marine Wildlife News" (taken from the BMLSS [British Marine Life Study Society] web page) in our February 2003 Newsletter (No.296) I thought that I was reading an article from the past. The paragraph, however, was dated late November 2002. It said that "A Short-snouted Seahorse, Hippocampus hippocampus, is captured by an oyster fisherman in the Solent. In Victorian times, there are records from off Dorset and the Solent."
(Dorset is a county on the mid-south coast of England. The Solent is a channel that runs between the Isle of Wight and the mainland, just off Dorset.)
I had first read a similar report about seahorse sightings in British waters in 1996. I had included details of the report in our July 1996 Newsletter (No.224). That report had said that seven seahorses had been caught off Dorset (at Weymouth) late in 1995. The report went on to say that two seahorses had also been discovered there in 1992. A seahorse caught off of nearby Sussex in 1990 had been the first one recorded off of England for decades.
Then, according to our August 2001 Newsletter (No.280), a lobster fisherman from Swanage (in Dorset) caught two seahorses in one week that year. They were both identified as Hippocampus ramulosus. The report (taken from the BMLSS magazine "Torpedo") went on to say that "Seahorses have been found from Weymouth Bay and the Fleet in Dorset and there are anecdotal reports of seahorses from Studland eelgrass beds, but about 20 years ago." That would have been about 1980.
The latest report (Nov 2002) harks back to sightings of seahorses in "Victorian times". Queen Victoria died in 1901.
I decided to check out the BMLSS web site and I found much information about seahorses and their sighting around Britain. The following reports for example :-
Late August 2002
Three specimens of the Short-snouted Seahorse, Hippocampus hippocampus, were discovered about 95 miles east of the Solent in the English Channel. They were picked up during DEFRA sponsored fish habitat studies by the University of Wales Bangor research vessel Prince Madog. Each came up in separate gear deployments, though at a single sampling station. On UWTV the benthic biotope where they came from was seen to be sand with a dense bed of tube worms, Lanice conchilega. All three seahorses were "pregnant" males.
1 November 2001
There have been further reports of Short-snouted Seahorse, Hippocampus hippocampus, from around the Channel Islands. Fisherman Steve Ryall hauled them up in his nets together with Lumpsuckers and large Soles over 3 kg in weight. The Seahorses were returned alive. Lobster and crab fisherman Andy Egre reports catching two large Seahorses in his pots about a mile and a half off Rozel in 30 metres of water in an area of strong tides.
27 September 2001
A commercial fisherman, Rick Ferbrache, caught a 63 mm (2.5 inch) long brown Short-snouted Seahorse, Hippocampus hippocampus, in a parlour crab pot while fishing 1.5 miles north west of Pembroke off Guernsey's north coast.
10 November 1999
A Seahorse, Hippocampus hippocampus, was caught in gill nets about one mile south of Guernsey in about 10 metres of water. The seahorse capture was in another net set along another part of the south coast of Guernsey at 49° 25.06' N and 2° 33.41' W. This capture was near rocks called Pecheresse to the east of Icart Point.
The Seahorse, Hippocampus hippocampus, was recorded off the Netherlands coast in the late nineties.
3 specimens of the Seahorse, Hippocampus hippocampus, caught in deep water, over 30 metres, off Jersey by lobster fishermen. These attractive small fish are regularly caught during the winter. The Sea Horses have found a home at the National Aquarium in Plymouth.
On 14 February 1997, William Falla, caught a Seahorse. Hippocampus hippocampus, at a depth of about 55 metres south of St. Martins Point, Guernsey. This specimen was recovered alive and housed in a home aquarium.
On 13 February a female Seahorse, Hippocampus hippocampus, was caught by Mark Blondel fishing for spider crabs in 60 metres (200 ft) 8 to 10 miles SE of St. Martins Point, Guernsey.
On 30 January 1996, a Short-nosed Seahorse, Hippocampus hippocampus, was caught by an Alderney fisherman in a lobster trap. This is the rarer of two seahorses recorded in the English Channel and is caught with some frequency in deep water (over 30 metres) around the Channel Islands. One individual was caught off Jersey a week before, and another one just before Christmas off Alderney. There are 13 records from off Jersey for 1995. The latest specimen was returned to the sea.
The Marine and Estuarine Fishes of Wales shows confirmed records of the Seahorse Hippocampus ramulosus in north Cardigan Bay, Pembrokeshire and the Severn Estuary.
And then this information about the seahorse Hippocampus ramulosus.
Hippocampus guttulatus. This is still known as Hippocampus ramulosus until the identification and renaming has been approved in Switzerland by the nomenclature society. They start to breed at about 6 months but are seasonal.
And these details about a seahorse book: -
"Every year, huge numbers of seahorses die in aquaria as a result of the lack of accurate information on how to keep them. This book redresses the balance by giving a comprehensive account of how to care for these most difficult of marine fish, but also stresses the need for conservation in the wild".
Feeding live food to seahorses is more likely than not to be an insurmountable problem for the home aquarist, and anybody wishing to keep this fish will need to buy this book. If you are just interested in these fascinating fish the 48-page book contains information not published elsewhere.
The details from our July 1996 Newsletter were also included in my "Seahorses" article in our December 1996 Journal (No.7). In that article I explained that "Seahorses belong to the Genus Hippocampus. All members of this genus have a forward inclination of the head, the length of which is at an angle with the length of the body."
The article also referred to Short-snouted Seahorses as Hippocampus breviceps. Ralph Richardson’s article in the same Journal called Hippocampus breviceps Short-headed Seahorses. Both common names are acceptable. The Short-snouted Seahorses from England are a different species (Hippocampus hippocampus). They are also referred to as Short-nosed Seahorses above.

The Seven Gills and The Single Shield
(Easter on Y. P.)
I'm sure readers are not yet thoroughly sick of my favourable comments concerning my Shark Shield so I've stretched my imagination again to concoct this title!
On a night dive (18/4/03) at Edithburgh Jetty we started off as a three-some, but as usual when I'm the sole photographer Paul and Leona Fitzgerald soon became frustrated with my slow progress and headed off towards the outer end.
While gearing up Paul had stirred the proverbial out of me with jocular comments such as "The day I wear a Shark Shield on a jetty dive will be the day I quit diving" and "Only a wimp like you would bother".
But Paul was strangely silent on this subject after the dive because Leona saw a sizable shark eating a dead ray under the jetty's outer end!
She only had a glimpse as it abandoned its ray meal and turned tail and fled out to deeper water. But from Leona’s description of its long, thin, almost eel-like tailfin we guessed it was probably a Seven-Gilled Shark. (And if you thought my sense of humour was pathetic, try this out: Paul then commented that, strictly speaking, they should be called ‘Fourteen-Gilled’ Sharks for obvious reasons!)
Apart from the ray there were also a disturbing number of dead smaller whole fish (ie unfilletted) under the jetty. These were mainly slimy mackerel a species often used in craypots as bait. One suspects these were dumped overboard towards season’s end. If so, this would not have been with the intention of attracting sharks of course, but nevertheless such shoddy behaviour can hardly be put down to ignorance, as few if any crayboat skippers using this jetty would be unaware of its intensive dive tourism focus.
Although I'd be drawing a long bow to speculate that Leona or Paul (but not me - I was wearing protection!) could’ve been attacked as a result, one does wonder….
Footnote: On a lighter note, I got some nice piccies of two of these slimy mackerel carcasses being consumed by hordes of isopods. It’s an ill wind that blows noone any good!
