A
jack fish known as the Blue Runner,
Caranx
crysos, was caught by a fisherman in a bass net just off Mevagissey,
Cornwall, and taken in to Chris Gilbertson
at Mevagissey Aquarium,
who passed it on to me for identification. This is thought to be the fourth
or fifth specimen of this fish reported in the UK.
The
jack family of fish (Carangidae) are widespread in the warmer waters of
the world, but the only member of the family which is common in the North
East Atlantic is the Horse Mackerel or Scad Trachurus trachurus.
Carangids seem to be being found more regularly as the temperature of local
waters increases.

One
of the most extraordinary shark tales involved the discovery of a tropical
Oceanic
White-tip Shark,
Carcharhinus
longimanus, that had badly lost its way and was discovered swimming
around a warship in a brackish water fjord near Gullmarsfjorden in west
Sweden. It died shortly afterwards. The shark, a male, was 230 cm long,
(total length), and weighed 65.65 kg. This is the first record in northern
European seas and it has never been discovered around the British coast.
A Swedish Museum in Gothenburg has now the shark for further examination.
The
Oceanic
White-tip Shark is found worldwide in epipelagic
tropical and subtropical waters between 20° North and 20° South
latitude. Its range is from Portugal to the Gulf of Guinea in the eastern
Atlantic. There are a few records from the Mediterranean Sea. It lives
in sea temperatures above 21° C. It is usually found over deep water
a long way from the shore. It is known to assocauite with Pilot
Whales and may follow boats or ships if a
constant food source is available. This shark has a reputation for attacking
Man.
How
could the shark have arrived in the fjord? The speculation could involves
man's activities as a discard from a deep water fishing catch?

A Sowerby's

in the day a similar whale was stranded at Llangrannog near Newquay in
Wales and successfully helped back into the sea.

Pair
trawling for sea bass banned in UK Territorial waters
Fisheries
Minister Ben Bradshaw has announced a unilateral ban on pair trawling for
seabass effective immediately at the Labour Party conference in Brighton.
The
ban will be implemented within the 20 km (12 mile) limit of the UK's waters.
This will not prevent the dolphin deaths but will prevent any more damage
to inshore breeding grounds.

The
massive stranding of By-the-wind Sailors,
Velella
velella, has now been established
that it has stretched much further than just the Cornish coast and that
the numbers were in billions. Reports of large numbers of large specimens
and huge numbers occurred all along the Welsh coast as far north as Anglesey
and almost certainly further north as well.

Velella
were
found on the shore between Newquay in Wales and Aberaeron with a
length of 60 mm +. There was one every three metres or so around the rocks
at Cei Bach thinning out in the sand areas. All were strikingly large compared
to those I have found before in south Wales and Cornwall before. All had
soft tissue and colour but were dead and disintegrating.
Early
September 2004
We
found large amounts of Velella velella
out off the Pembrokeshire coast back at the start of Septernber and the
ensuing storms seem to have deposited many of them on our beaches in the
west of Pembrokeshire (at least). Their small size make them easy to overlook
at sea and also on dark sand but they are exquisite jewel like creatures.

A
huge mass
stranding of By-the-wind
Sailors,
Velella velella, occurred
all along the north Cornish coast from Sennen
Cove (near land's End) up to Polzeath (near Padstow) and beyond. (As
the gull flies this is a distance of 25+ miles and with all the coves and
inlets the shoreline is over double this.) Coming in on the top of the
tide, there were hundreds of millions* of them, all large, the largest
I found was 85 mm, and all them were intact. Millions of Barnacles
were washed up along the strandline.
(*
Numbers not calculated. At Gwithian they formed a band 10 metres wide on
the shore and stretching for over a mile. The above photograph understates
the extent of the stranding.)
The
Buoy
Barnacles, Dosima fascicularis (=Lepas),
started
coming in on the same tide as the Velella.
I've seen with my own eyes on Porthcothan (SW
8572), Treyarnon and Constantine and Paul
Gainey saw them on Gwithian, all in north
Cornwall. I'd be very surprised if they weren't all the way up the coast
and I'd number them in millions, all big. The Goose
Barnacles,
Lepas, are occurring
in their usual quantity for this time of the year, if anything, less. To
give you an idea, on my beach, Pothcothan, 25 acres at low tide:
Velella
approximately one million, Buoy Barnacles:
2000+, Goose Barnacle
colonies: 7.

An
Amberjack
Seriola
sp., caught by an angler off the rocks of the Lizard peninsula, Cornwall,
in mid-September and taken to Matt Slater
at the Blue Reef Aquarium
in
Newquay
for identification, will be a new British rod-caught record. It is
thought to be a Lesser Amberjack,Seriola
fasciata, which has never been recorded in Britain before, but could
turn out to be an Almaco Jack, Seriola rivoliana, which would be
the sixth for British waters, and the first taken by an angler.

Brian
Richardson diving in 18 metres of water off
the South Devon Coast thought he saw the unusual echiuran species known
by the scientific name of Bonellia
viridis. Only the proboscis
was seen, which was about 60 cm long with a T piece 10 cm wide. When touched,
the expandable proboscis recoiled under a rock.
I
expect most people have not had a chance to see such a bizarre and unusual
creature.
Image
of the this species discovered off Norway (to see how bizarre it is)
Link
to the Second Photograph of the extendable proboscis by Rudolf Svensen
This
"spoon" worm is classified in the Phylum Echiura.
The
females of Bonellia viridis
are up to 2 metres in length, while the males are merely 1-2 mm (!) and
live as parasites within the uterus of the female! This is the most extreme
size difference between male and female (called "sexual dimorphism") found
in the animal kingdom!
This
is not only strange things about the bionomics of this peculiar animal.

Bonellia
viridis Information Page (by René Hessling)
The
distribution of Bonellia viridis around
the British Isles is unclear. I have not received any reports from divers
in British waters before, although off Norway it will be found in depths
of 25 metres, but usually deeper. It frequents shallow water in the
Mediterranean Sea, e.g. off Chios,
a Greek island in the Aegean Sea.

The
Sunfish,
Mola
mola, photograph was taken
on 7th August 2004 about
half a mile off Old Harry Rocks in Dorset. I spotted the Sunfish on the
surface and I have seen them in the same area before. Normally when approached
they swim towards the bottom at high speed. This time the Sunfish swam
towards the boat and even allowed me to touch it, it made no attempt to
swim away. It swam around the boat a few times and came back to the swim
platform again. I could see it had sea lice on its back and I guess it
was trying to get them removed. The fish appeared to be in good health,
a fantastic site to see.

Fishing
the River Hayle in Cornwall, in the evening, I caught three Gilthead
Bream, Sparus aurata, one of about
6-7 cm and two of about 16-20 cm long. All three were released. There
may well have been a large number of the little bream as my bait was attached
by small fish almost every cast.
NB: Gilthead
Bream is a southern species which is now believed
to breed off the south-west coast of Britain.

Balaenoptera acutorostrata.
I've spent many hours with it over the last week (we have a team up there

This

Lamna

Sea. Their occurence may match the Salmon
on which they prey. Specimens washed up dead on the beach are unusual.

While
diving at the Shiant Isles in
the in the Minch between Skye and Lewis in the Outer Hebrides (islands
off north-west Scotland) I found the large starfish Stichastrella
rosea, an echinoderm I have never
seen outside of St Kilda.
Better
still, I also found what looks like this starfish but it had seven arms
instead of the usual five. This starfish seems to be uncommon and found
off the northern and western coasts, usually in deeper water than 30 metres
so it is rarely seen by divers.

some followed behind riding in the wake while a group at the front were
bow riding within a few metres of the vessel.
