Just wondered if anyone reading this forum has made aquaria out of plywood or
plywood / fibreglass composites. Have seen references to this on net - e.g.
excellent blog of Jon Olav from Norway
http://www.jonolavsakvarium.com/eng_diy/menu.html on this.
For those using chillers a plywood aquarium will mean lower electricity bills
and fewer condensation problems at low seawater temperatures. Jon Olav's blog
in particular has given me an entirely different perspective on aquarium
construction.
Good to see wetthumbs up and running again even though there is very low
activity - I will try and start my contributions again.

Hello,
Adur World Oceans Day this year will take place in the marquee on Coronation
Green next to Shoreham High Street on 6th June 2009 on the opening Saturday
of the Adur Festival. Len Nevell will be there with the usual exhibition of
lobsters and crabs. The innovative aquarium displays of seashore life,
strandline exhibits and photographs will again be in on show. Experts will
be on hand to answer your queries about life in the oceans and on the
seashore.
I think World Oceans Day this is best described by the Nobel prize winning
author John Steinbeck when writing about Ed 'Doc' Ricketts of Cannery Row
fame in which he wrote 'commercial fishermen harvest the sea to feed men's
bodies and a marine biologist harvests the sea to feed men's minds'
Quote by Andy Horton (British Marine Life Study Society)
The Friends of Shoreham Beach will again be playing an important part with
their own displays and information about the Nature Reserve and plants of
the shingle beach.
Cheers
Andy Horton

ADUR WORLD OCEANS DAY
Understanding and celebrating our marine environment
Adur will be one of the UK leaders in presenting the eleventh environmental
exhibition of World Oceans Day on Coronation Green, Shoreham-by-Sea. Find
out what lives in the sea and on the seashore off the Sussex coast, with
exhibits hosted by local experts and enthusiasts of the undersea world. Live
lobsters and crabs, a rock pool aquarium, the whale and dolphin exhibition,
a touch table of strandline exhibits found on the shore and other
interactive displays will be on display under the marquee on the green
overlooking the River Adur by the footbridge. For the third year running the
Friends of Shoreham Beach will be providing their own displays and playing
an important role in organising the day. Allow at least an hour for an
educational exhibition for the youngest to the oldest member of the family.
Exhibitors will be able to find the time to answer questions about marine
life.
Admission is free.
Adur World Oceans Day is run by a committee comprising representatives of
the British Marine Life Study Society, West Sussex County Council, the Sea
Watch Foundation, Friends of Shoreham Beach and other groups, with support
from Adur District Council.
World Oceans Day was declared at the Earth Summit in 1992.

Subject: [Glaucus] Adur World Oceans Day
Hello,
The page copy of the write-up for the Shoreview magazine can be found
at:
http://www.flickr.com/photos/shoreham/2711259376/
The original script was as follows:
During the Adur Festival of 2008 we celebrated the tenth anniversary
of Adur World Oceans Day in the marquee on Coronation Green. It was
not and has never been an arts or circus event; it has always been
designed by the committee including representatives of Adur District
Council and West Sussex County Council as an educational exhibit.
Within the limits of our resources and the one day format we designed
an exhibition to introduce children and adults to the wonders of the
sea and seashore, in a setting of historic maritime importance. The
public hards either side of Coronation Green were wharves of the
mediaeval port of New Shoreham dominated by the Church of St. Mary
de Haura.
The main exhibits with Len Nevell and the lobsters and crabs are
designed to show children at first hand what lives beneath the sea
off the Sussex coast. These have to be supported by the aquarium
displays of seashore creatures by Andy Horton of the national British
Marine Life Study Society, with a life support system to keep the
animals alive. Other displays in 2008 included the Sea Watch
Foundation exhibit of whales and dolphins information hosted by
wildlife writer Steve Savage, a display of vegetated shingle plants
an photographs by environmentalists David and Marion Wood, the
strandline exhibit by John Knight and Kathy Eels of West Sussex
County Council Countryside Unit and the displays by the local Friends
of Shoreham Beach. There is the opportunity to ask questions about
puzzling finds on the seashore of which there are many.
Just about every exhibit was an innovative and original concept since
copied by other groups, but the design was unique and trend setting.
One of our successes was the use of magnifying glasses so the young
children can observe the smaller creatures close-up in detail, to see
a Hermit Crab emerge from the shell of a winkle or another mollusc,
see the wavy venomous tentacles of sea anemones, a cute little fish
called the Blenny, the venomous Weever Fish as an identification
guide to avoid a painful sting, as well as learning how to pick up a
crab without getting their fingers nipped.
I think Adur World Oceans Day this is best described by the Nobel
prize winning author John Steinbeck when writing about Ed 'Doc'
Ricketts of Cannery Row fame in which he wrote 'commercial fishermen
harvest the sea to feed men's bodies and a marine biologist harvests
the sea to feed men's minds'
In June 1992, over 150 Heads of States signed the Convention on
Biological Diversity at Rio de Janeiro. They did so to express a
shared belief that action must be taken to halt the worldwide loss of
animal and plant species and genetic resources. World Oceans Day was
first declared as 8th June at the Earth Summit in Rio de Janeiro in
1992. Events will occur all around the world on and around this day.
Adur is one of the UK leaders in this initiative because of a
circular from Department of the Environment to local Councils
suggested this was one of the days that could be supported by local
authorities in line with the world wide initiative. Alas, these
circulars in the mass of paperwork often go unnoticed and slide into
the waste paper basket. Not this one, as I suggested to Natalie
Brahma-Pearl the environmental representative on Adur Council that
such an event could prove beneficial to both the town and the concept
and this was enthusiastically supported by her and Neil Mitchell of
West Sussex County Council.
The British Marine Life Study Society had participated in exhibitions
before and we had the knowledge and expertise to organise an event of
our own with rather limited resources. In the latter years we have
had valuable help from David Steadman of the Shoreham Economic
Partnership.
The British Marine Life Study Society was formed in 1990 to study the
sea and seashore and to exchange information about the life in the
oceans. It is not a conservation organisation but a wildlife and
ecology study group, funded by members subscriptions. For the first
ten years we produced paper publication including the national
journal called Glaucus and a newsletter called Shorewatch. At the
turn of the millennium, we moved with the technological changes and
distributed information through the web site and the European
electronic news bulletin called Torpedo, one of the first electronic
bulletins of its kind. The news pages on the web site produce marine
life reports from all around the coast of the British Isles from our
numerous contacts. This information put into the public domain that
might go unrecorded and in its small way narrates the changes that
occur, as a supplement to dedicated scientific study.

Hello,
On 14 June 2008, a Lesser Weever, Echiichthys vipera, spat out the uneaten
parts of a Common Goby almost as long as
the small fish.
NB: This means the fish could manage the smaller shrimps of the same size,
although by mid-June most of the Brown Shrimps would have died.
Beware of the Weever!

ADUR WORLD OCEANS DAY
Venue: Coronation Green, Shoreham-by-Sea
FREE ADMISSION
Adur will be one of the leaders in the United Kingdom when it presents an
Exhibition celebrating the official World Oceans Day. It will be held at the
large marquee on Coronation Green overlooking the River Adur .
Adur World Oceans Day a unique opportunity to introduce children to the
mysterious undersea and seashore world with displays of live fish, lobsters
and crabs, and a variety of exhibits on the ocean environment, including
talks designed for young students, and video and computer displays and
interactive displays and activities to keep the children occupied. There
will be a new displays for this year. The new "Friends of Shoreham Beach"
group will be presenting a special display to promote the new Nature
Reserve on the beach.
Peter Talbot-Elsden (who appeared on River Walks) will be presenting his
shrimp and shrimping information display (complete with shrimp nets as used
by Charlie Dimmock on the TV programme). Steve Savage will present the
Dolphin display on behalf of the Sea Watch Foundation.
OPPORTUNITIES FOR PRESS PHOTOGRAPHS ON THE DAY
There is something for all age groups and experts on hand to answer queries
about life in the seas. If you bring the whole family, allow at least a
couple of hours to participate in the activities. Refreshments will be
available on the green and in the cafes and shops nearby. Weather
permitting we should sea urchins and starfish for the children to have a
look at. Len Nevell is the man with the Lobsters.

I must say I was very supprised when you said that you have taken some Pachycerianthus before having had the pleasure of diving with them in Loch Fyne they are truly amazing anemones. However this has prompted me to look them up as I was pretty sure they they would have some protection. The best way to be sure though would be to contact Scottish Natural heritage (enquiries@...) and ask them specifically including the locality.
From what I have read on the internet, I understand that Loch Duich is designated as a marine Special Area of Conservation and therefore of European Importance. I am not familiar with this area but I gather this is for the sheltered rocky reefs there for which Protanthea simplex(amongst other species) is listed on the Site Account (http://www.snh.org.uk/pdfs/about/directives/Lochs_Duich_Long_and_Alsh_Reefs.pdf). the Loch is also noted for its particularly rich deep muds and burrowing megafauna which are a Biodiversity Action Plan Habitat. Although the Pachycerianthus may appear to be locally abundant in the loch it is actually nationally important and deemed to be scarce (http://www.marlin.ac.uk/species/Pachycerianthusmultiplicatus.htm). Pachycerianthus is a long-lived and slow growing species (http://www.jncc.gov.uk/pdf/all_Marlin_dossiers.pdf) and would therefore be highly sensitive to removal ie I expect this is a highly unsustainable activity.
I would imagine that to keep one successfully in a tank like at the aquarium you mentioned you would have to have a very larger tank set up specifically for them with a very deep layer of soft mud ( I guess 50+cm?) with maybe a metre of water above and very gentle water circulation. Something dificult to acheive on a domestioc scale...!
Good question Divemouse.....I've never seen anything saying that they are protected....if anyone knows for sure, let me know and I obviously wouldnt remove one. Like I said, I collected a few for an aquarium and they are all still going strong three years later and look spectacular in their tank.
I personally had no reservations about collecting a couple from Loch Duich, where I know from experience that you can get concentrations upwards of 30 within sight at one time and a good few hundred per dive. I would never remove one from a spot with only a small number of specimens.
Like I said...If anyone has evidence that they are in any way protected let me know.... Chris R.

I have a Teco RA680 chiller on my large tank which gives me a controlled temp of 15 degC for up to 800L capacity.It pulls 420 Watt so can be expensive with our warming climate.I was lucky to find a person in Colchester who must have bought a job lot and then resold to get a free one out of the deal,at the time some 3+ years ago I paid about £400 and saved at least £150.The unit requires a flow capacity of 400L/hr.I have looked up on the internet for a smaller unit for my smaller tank but all those I find give all the so called technical details like cost,weight and size but fail to mention the capabilities of the chiller like temp drop versus ambient which is quite important.The RA range of Teco chillers have been superceded by a TR range.The Teco data sheets include graphs of temp reqmts,volume of tank,tank construction.Their office technical backup is superb.One of our problems is to keep the power to run the tanks down like lights,powerheads,pumps in the fishhouse otherwise an extra load is put onto the chiller.Hence my chiller is located outside of the fishhouse.If you have not used a chiller before one piece of advise.It is recommended that every 6 mths the flow through the chiller is reversed to remove scale,make sure you place a fine mesh net over outlet to catch the rubbish.I am trying to contact the person I bought the chiller from to see if he has any more that may be suitable,I will let you know how I get on.Diadume Cincta as you know are very small anemone's and I am having problems keeping them,temp is not contolled in the tank I have them and can get up to 25 degC which is why I will get a second chiller.I try to feed with small pieces of mussel and liquid plankton but I think the plankton is too small and the mussel is difficult to take as they do close very quickly.I have bought some feed called marine snow which I hope is larger particals which will be a more natural way of feeding.I have seen a few Diadumene in the crouch estuary and the Burnham marina but on the Wallasea marina pontoons south bank of the Crouch they are plentyfull.The only problem with Wallasea is that they have a very unhelpful harbourmaster who will say no before you have even spoken.Getting permission to go onto the pontoons is necessary because you need the security number of the gate.I do have a phone number for the office but its best to make the request in person.Weekdays are better than weekends when they can get busy.If you intend to visit wallasea I can tell you exactly which part of the pontoons to look to save time,on my first visit I was given 10 minutes.I hope to visit wallasea next week.If you are ever in the Burnham On Crouch area give me a ring on 01621-782357 and you are welcome to call in.If I find Gem anemone's on my hols this year would you like me bring back a few for yourself.Referance your letter,I agree that a tank of sea anemone's can be so colourfull,interesting,therapeutic, time consuming and challenging to a non marine biologist like myself.
I read you message with heartfelt agreement. I had a stroke many years ago and now am a poor swimmer and diving is definitely off limits. It means that I cannot see jewel, tube, policeman, cluster anemones and Devon cup-coral etc. in the wild.
I have also been wondering if there is a member of the diving commutity out there who could get some specimens of anemones for me. The trouble is, most modern divers are brought up in a conservation mode and look down on us "collectors". It used to find a similar mindset sometimes when I worked for a museum service. I did taxonomic work and there is no way you can do that without collecting and preserving specimens. I collected a lot but I also described several new species for the UK and for science.
I too would go anywhere to collect the specimens. I would love a tank of green and pink jewel anenones. (Guernsey, there they grow on pontoons in a marina according to R Lord's photos).
I am interested in your tank set up. What type of chiller do you use how much did it cost? How well dose it work? I have several tanks of coldwater beasts, the largest being 5foot long but it can get up almost 20 degrees in the summer which is too warm for eg.Dahlia anemones. I need to chill it in some way. I also have a 5foot tank of tropical marines that contains corals and anemones from warmer waters. There are several Aptasia anemones which are "pest" species in it but I have never seen the trumpet anemone from UK.
I like anemones and I think that a tank full of just anemones is fabulous. I had a Sepiola, see above, but one day I checked the tank and it was nowhere to be seen, despite searching every square inch. The answer, I think, lay in a very fat snakelocks anemone.
I have never seen Diadumene cincta, where do you collect it from.
I have mainly plumose and Sagartia troglodytes which are common in the sea off Norfolk. I have a considerable number of the latter, various colour combinations and some are S. troglodytes for sure and some of them I not too sure about. Sagartia is such a variable "species" that I shall watch them and wait and see. I have a couple of daisy anemones from Hants for comparison.
My beadlets also loose their colour and become washed out pinky brown. I think it is a lack of "vitamens". Tube worms do much the same, they are bright orange/red when I collect them but the fans fade to a pale pinky grey in time.
I am off to Ireland next week but I shall be back in a couple of weeks. I too am going down to the SW in Sept. When there are low tides. You never know what you will find, with luck.
Hi Jim,
I read you message with heartfelt agreement. I had a stroke many
years ago and now am a poor swimmer and diving is definitely off
limits. It means that I cannot see jewel, tube, policeman, cluster
anemones and Devon cup-coral etc. in the wild.
I have also been wondering if there is a member of the diving
commutity out there who could get some specimens of anemones for
me. The trouble is, most modern divers are brought up in a
conservation mode and look down on us "collectors". It used to find
a similar mindset sometimes when I worked for a museum service. I
did taxonomic work and there is no way you can do that without
collecting and preserving specimens. I collected a lot but I also
described several new species for the UK and for science.
I too would go anywhere to collect the specimens. I would love a
tank of green and pink jewel anenones. (Guernsey, there they grow on
pontoons in a marina according to R Lord's photos).
I am interested in your tank set up. What type of chiller do you use
how much did it cost? How well dose it work? I have several tanks
of coldwater beasts, the largest being 5foot long but it can get up
almost 20 degrees in the summer which is too warm for eg.Dahlia
anemones. I need to chill it in some way. I also have a 5foot tank
of tropical marines that contains corals and anemones from warmer
waters. There are several Aptasia anemones which are "pest" species
in it but I have never seen the trumpet anemone from UK.
I like anemones and I think that a tank full of just anemones is
fabulous. I had a Sepiola, see above, but one day I checked the tank
and it was nowhere to be seen, despite searching every square inch.
The answer, I think, lay in a very fat snakelocks anemone.
I have never seen Diadumene cincta, where do you collect it from.

Cold Water Marine Tank experience
3 years ago I set up an 8 ft 200 gallon cold water marine tank and
added 18 months ago a 4ft tank which I divided into
4 compartments and only partially filled.The large tank has a
biological pond filtration system in line with a uv steriliser,a
protein skimmer,4 header pumps for water agitation and a chiller
which maintains the tank at 15 degC.The lighting is 2 off
4ft 38W interpet triplus tubes.The small tank has just a 4ft tube and
a header pump in each compartment agitating and
aerating.I replace 50 gallons of water from the large tank every 3
weeks with fresh sea water from the river crouch.
20 gallons of the 50 from the large tank replaces the 20 gallons in
the 4ft tank.
In large tank I keep snakelocks (brown and green
varieties),plumrose,dahlia,strawberry,daisy,beadlet.
cushion stars,urchins,prawns,ells and 4 shanny fish.
In 4ft I have daisy,gem,sagarta and diadumene cincta.
I feed with frozen pink and brown shrimps,mussels which I collect
from the river and frozen plankton.
I have the following queries and observations regarding the species I
am keeping.
BEADLET. The deep red specimens lose their rich colour and tend
towards pink / brown colouration.WHY ????
DAISY My specimens spit out young regularly but on one
occasion an additional one of significant size appeared
which could only have been the result of longitudinal
fission. IS THIS KNOWN FOR THIS SPECIES.
DIADUMENE CINCTA. I did have a genuine white species.IS THIS
COMMON ????.This species has not been easy to keep
but I am gradually getting there.
SNAKELOCKS small specimens appear to breed small and large
breed large,ARE THEY IN FACT TWO DIFFERENT SPECIES.
SAGARTIA I have read that one of the means of
identifying elegans from trogladyts is that there are no grains of
sand / gravel on the column of the elegans.I
have some species which have the column completely
covered with small gravel particles and
others which often have none but occaSionally have a few.Is it
known that elegans can have some particles
attached to the column.??????
PLUMROSE I find this species shuts down untill it can smell
food in the water when it will open up.The marina
pontoon where I find my specimens is an area
which looks semi polluted.
DAHLIA I did have problems which I have previously
reported, of this species shutting down and difficult to feed.
I reduced the tank temp from 17 to 15 degC and
added localised light shields to darken the area of the
tank that the species were located,this was
suggested by Richard Lord from Guernsey from his diving
experiences.I am glad to say that the
suggestion works most of the time,I just need to improve on the
light shield system.
Unfortunately I have a medical problem with one of my ears which for
most of my life has prevented me from swimming
and a recent 2nd operation has certainly put paid to any ambitions I
might have had to swim in the future.I therefore can
only search for tank samples in relative shallow rockpools.If anybody
out there has any data on where I can find a couple
of specimens of the Trumpet anemone or has any spare specimens of any
anemone not mentioned above that I could
collect I would appreciate it very much.Are there any divers who
could get me a few samples of the jewel anemone please
I will travel anywhere in the UK to collect.
Later in the year I would like to look for some anemone's in the
Plymouth to Penzance area,any recommendations as to
which specific area I should look at.
I have recently joined a local shoresearch initiative set up by Essex
Biodiversity Project and essex wildlife,they intend to
add the marine search info into the national database 'Marine
recorder'.

The other day as I was returning with my shrimping net (a modified pond net) I saw a moving object in a rock pool. Imagine my surprise and delight when I looked in the net and found I had caught a lesser cuttlefish. I have it in my tank but it is still sulking after two days and spends the time buried in the sand. There are lots of small shrimps in there with it but I was wondering what dose it normally eat? Does anybody know? I'd like to tempt it with its favourite food. Does it eat small crabs like its larger relative?
