ADUR
WORLD OCEANS DAY
Venue:
Coronation Green,
Shoreham-by-Sea
Adur
was one of the leaders in the United Kingdom when it presented an Exhibition
celebrating the official World Oceans Day. It was
held in the large marquee on
Coronation
Green overlooking the River
Adur.
I estimated
the attendance on a sunny day (21.4° C)
at 2,500.
With
the sheer number of people it made it impossible to speak to people as
much as I would like. There were lots of interesting conversations and
I was surprised about the number of people who stepped on a Weever
Fish last summer, at least half a dozen, and it was lucky we had
a small specimen on display so people could have a look at the offender.
The
most interesting discovery was an unidentified fossil found on Shoreham
beach and brought in by a young girl. This is illustrated on the right.

A Box
Crab, Paramola cuvieri,
was caught 12 miles off Falmouth by fisherman
Arfee Treneer, from Mylor, Cornwall. The extremely
long legs of this deep water crab give it by far the largest span of any
of the crabs found in the North-east Atlantic Ocean, although its body
is not much larger than the Spiny Spider Crab,
Maja
squinado. It is a rare capture and
according to the BBC Report only the sixth ever caught in British seas
and second by this fisherman. This crab like all the giant long-legged
crabs is an inhabitant of very deep water in excess of 150 metres and down
to depths of 1500 metres. This one was caught in much shallower depths
and brought alive, but damaged, to the Blue
Reef Aquarium at Newquay. The bionomics of this crab are not well known.

A
Sturgeon,
Acipenser sp., was caught
in an otter trawl in Bristol Channel south of Swansea at 2:30
pm in the small (under 10 metre) fishing vessel
MFV
Wonkey SA357, skippered by Robert (or Kevin) Davies.
It weighed 120 kg (265 lb), and was was 261 cm (8 ft 6") long (including
the tail fin) and 246 cm long (excluding the tail). It was caught at a
depth of between 10 and 20 metres.I believe it to be Acipenser
sturio, but the snout is fairly short
and blunt, more like Acipenser gueldenstaedtii
(but
this is a Danube/Black sea species).

Three
professional anglers witnessed a Thresher
Shark, Alopias, leap completely
out of the water, tail and all, four consecutive times to the west of Alderney,
Channel Islands, Great Britain at about 8:00
pm. One angler told me that he estimated the
body length of the shark at about 170 cm. The leaping activity occurred
about 100 metres away from their boat. The leaps were head first and perpendicular
out of the water. The anglers were drift-fishing for Bass,
Dicentrarchus
labrax, approximately one mile west of Garden Rock, which has a
large Gannet
colony covering the entire rock. Atlantic Mackerel, Scomber
scombrus, were also in the area.

Three
molluscs known as Akera bullata
were seen swimming on the surface of the sea and scooped into a net from
the south-east corner of Queen Elizabeth II Marina, St Helier, Jersey,
in the Channel Islands (English Channel). Most
gastropod (snail-like) molluscs with shells crawl over the rocks and cannot
swim, so the very sight of a shelled animal on the surface of the sea is
likely to provoke curiosity.
Akera
is a primitive representative of the Anaspidea (Sea Hares), an opisthobranch
gastropod mollusc. It
has an fragile external shell which protects only part of its body and
the mollusc is reported to spend most of its time burrowing in soft mud,
but is capable of sporadic periods of swimming and eats algae.
The captured specimens were only three out of about ten and were only about
25 mm long and were returned to the marina after identification. This appears
to be the first record for Jersey in a marina that provides a home for
other southern species with unusual records in the recent past. Information
about the biology of Akera bullata is exiguous and it is only
known to British rockpoolers as part of a mass
stranding at Torbay, Devon. Its known habitats include sheltered bays
with Eelgrass,
Zostera
sp., and it has been reported all around the British coasts, from Norway
to the Mediterranean Sea and down to depths of 370 metres, so this a widespread
species, but with habits that mean it is not normally encountered by man.
It is also reported to have years of abundance so it is a bit of a surprise
that it is not more widely known.

A
small subsp. farrani population of this mollusc occurs in the Fleet
Lagoon, Dorset.

After
the recent gales have battered the north-west of Cornwall, large amounts
of kelp has been
washed on to the shore all around Trescore in the recent gales and left
rotting on the beach at Porthcothan (south of Padstow). With the tonnes
of washed up seaweed there were a large number of Sea
Hares, Aplysia
punctata, which feed on the small seaweeds and epiphytes on large
weeds. These Sea Hares
have years of abundance and they were observed in appreciable numbers in
November
2003.
