Ringed Plover

Hello Birders,

I am trying to investigate the reason why the Ringed Plover often fails to bring up its young in the vicinity of humans.
 

Ringed Plover
It is a shingle nesting bird. Several possibilities have been suggested:

Humans get to near the nest, frighten the bird off a or trample the eggs. I would expect this to occur when public pressure on the beach is too great.

However, often this little bird persists quite near seafront houses and other possibilities I wish to consider.
 
 

These include:

1)  Dogs sniff out the nest.
2)  Cats catch the birds or find the nest.
3)  Crows find the nest and eggs.
4)  Foxes get the nest and young.

Does anybody know of any research that has been undertaken on this subject, or failing this, has anybody got any anecdotal observations. 

The nests are difficult to discover, but sometimes small indentations in the shingle are all that remains of an attempted nest site. Often, the first indication is the feigning behaviour when the Ringed Plover attempts to distract anybody or any animal that ventures too close. 

Cheers

Ringed Plover nests are susceptible to many predators, but fox, badger and carrion crows are probably the major problems here at Rye Harbour. Barry Yates ( Rye Nature Reserve)

I would put the most likely causes of Ringed Plover breeding failure, as seen from our windows overlooking the shingle beach, as 1. CROWS, 2. Foxes, 3. Dogs, 4. Human disturbance, 5. Other reasons.  David Wood (Shoreham Beach)

Hi Andy,
I saw your message about Ringed Plovers on the BMLSS forum page.
I've just been working as a warden on a reserve monitoring breeding success of birds: amongst them ringed plover.
I found that even if predators do not find the nest, and it is not trampled on, the birds often failed to raise young in areas with a lot of disturbance because of their method of trying to protect their nest. a good example of this is a bird who nested outside my caravan right on the footpath across the island. Every time I stepped outside or walked past my window, the bird got off it's nest so causing chilling of the eggs. Eventually, after a longer than average incubation time, 2 eggs did hatch, but every time a person was near, the parents would run off down the beach doing a broken wing act worthy of an oscar nomination but completely abandoning the chicks and leaving them at the mercy of predators. The parents spent so much time doing this that the chicks did not have enough feeding time, I don't think, and did not survive long. 
Hope that is of some interest. I'd love to know your findings. I'm constantly battling with fishermen and dog walkers trying to prevent disturbance.
Good Luck

Atlantic Eels Anguilla anguilla

 I am a proprietor of a river on the west coast of Scotland (River Shiel, Ardnamurchan, Argyll).  In past years we had a substantial run of eels during the month of March . In fact there was such an abundance that we were able to sell these returning eels for aquaculture purposes.  I am pleased to say that the eel industry was unsuccessful but, be that as it may,  we do not appear to have these runs anymore. 
 Can anyone shed any light on this situation?

Hello,

Catch Tentacles in Metridium senile
 

My research indicated that dissection of Metridium senile failed to discover separate "catch tentacles". Now, anybody who has any experience of this anemone (English Channel specimens) will discover:

1)  catch tentacles appear on certain occasions
2)  introduction of plankton, brine shrimp, fresh seawater can (not always) induce the appearance of the "catch tentacles" in this species. 

Certain hypotheses can be thought up from these observations. However, further information would be useful. 

The questions are:

1) are "catch tentacles" regularly found in pickled specimens of Metridium senile?
2) what distinguishes the "catch tentacles" in dissected specimens from the ordinary tentacles (apart from the length and size)?

If anybody has investigated this anemone and knows the answers to these questions, I would be very interested. It will help formulate a description of what happens. I might even be able to suggest a reason why. (I have already thought up the reason and now I have to check it out.)

Gosse christened this anemone PLUMOSE which is widely (almost 100%)  used in the UK and it is a very apt and attractive name. 

Cheers

Sting Report

Steve Chapman (Stoke Newington) was swimming off the Camber Sands (near Rye), East Sussex, at the beginning of September 1999, when he felt a slight wasp-like sting, which was not really apparent until he left the water. The wound was on his lower leg and was small, not even finger sized, about 13 mm x 9 mm, red and sore with about 10-15 scab-like pin pricks which looked infected. After he rinsed his leg the slight sting was relieved and he was just left with a small wound. Picture.

Is this is a jellyfish sting? The species most often responsible for stinging swimmers is the Lion's Mane, but these are rare off Sussex. It could be the Compass Jellyfish, Chrysaora hysoscella, which is more often encountered in the eastern English Channel and has a reputation as a stinger. 

Is anybody able to confirm this is a jellyfish sting from their own experience?
Or could it be a Lamprey (see below)?

Mystery Experience

28 July 1999
I wonder if you could help me identify a fish. Last Sunday I was swimming off the beach at Folkestone, when I felt something on my thigh. I stopped and put my hand onto my leg and felt, what I thought, must have been an eel. It felt as though it was about 75 mm (3 inches) in diameter. I panicked a little, and had to pull at it to get it off me. I went ashore, and had a red circle around 25 mm (1 inch) in diameter on my upper thigh. It had drawn blood, and there were several areas within the circle which at first appeared to be holes, but now seem more like teeth marks. There were also 3 streaks of redness below the circle.
I have been swimming in the sea for over 30 years and never come across anything like this. I was only about 10 metres (10 yards) from the beach, which was packed at the time.
Have you any ideas please?
I look forward to hearing from you.
David de la Mothe.

This could be a parasitic attack by a Lamprey, Petromyzon marinus

I have been attempting to identify the larval stages of Palaemon elegans as reported in the scientific literature and have come across some discrepancies. The first 4 zoeal stages are easily identified, as is stage 5. After this point the development of the larvae to postlarvae either follows one (zoea 6) or two (zoea 6 & 7) but I am unable to find any accurate descriptions for the identification of these stages. Any assistance would be greatly appreciated.

 Aquaria with seaweed and animals from the Norwegian coast

Hello Andy Horton. 

(I hope you understand my spellings. I guarantee you that my aquarium knowledge is a great deal better than my English knowledge) 

I have visited your web: 
wetthumb.htm

I am delighted to finely have found a person that has an aquarium with animals from a Temperate Zone. I have only found tropical stuff. 

I like to present to you this picture of my aquarium with seaweed's and animals from the Norwegian coast. 

We have succeeded with seaweed in a closed aquarium system. Do you have any experience, or do you have knowledge of others with seaweed in the aquarium? 

My tank holds 260 litres of sea water. 

Are you able to get me in contact with people that shear our interest. 

This was many questions, but I really would appreciate an answer from you.

Can you identify this sea anemone?

I need help to identify a sea anemone I saw in my last dive. I live in Spain, in the northwest coast, in a region called Galicia. In this land, the coast form large estuaries, called "rias", in the mouth of the rivers. In  the "rias" there are a 
great amount of organic particles, the temperature is lower and the 
water less saline than open ocean. This conditions are good for aquatic 
cultivation, and the Mytilus galloprovincialis grows well. I dive the 
last time beneath a cultivation unity of this mollusc, called here "vatea", to a deep of 13 m (at 42º46,488´N/8º57,651´W). The bottom is  muddy. 

In this habitat I saw a white sea anemone bigger than I have ever seen before.
The central disc was more or less 15 cm of diameter, and its tentacles spanned 30-35 cm.

Ah, if I'd known it was from Galicia I would called it Andresia partenopea.

Dolphins in the Trent?

Is anybody able to bring any light and further information about some dolphins (or porpoises) reported from near Gainsborough on the River Trent? 
White-beaked Dolphins?

Mystery Animal (probably a mollusc)

Found at  Beer Cove, near Seaton in June 1998. 

Colour is best described as a grey(ish) brown(ish), with off-white under
parts. 

Length:  37 mm   Width  18 mm

The underside is similar to the average mollusc (gastropod [i.e. snail-like, or slug-like] or bivalve [i.e. cockle]?), and has a definite separate mouth part.

Hairs around the edge on mine are white(ish).

Shell isn't hard as in a snail shell, more along the lines of the outer coating of a squash ball, firm but flexible. (This statement has been revised - now reckoned to me a hard shell). 

Yes, my creature does move about the tank quite a lot, but only at night. Once the main lights have gone off and just the actinic lamp is on , it will stir itself and get ready to forage, but will not come out until the tank is in darkness. Even during a spell of night time watching with a shaded torch, you'll not see much of it. The instant the light falls upon it, it's off into the rockwork. Sometimes the lights do catch it out, and then it's like an aquatic greyhound antennae in and flat out for it's bolt hole!

Haliotis are more difficult to identify if you include the possibility of non-European species, not found on a rock afterall.

    Hello Andy, 

    Stone Crab

    I am currently involved in an experimental fishery for Northern Stone Crab (Lithodes maja) in Nova Scotia and have read that this species occurs in European waters. I have been searching for anything relating to this species. It seems very little scientific work has been done on this side of the Atlantic. 
     We have had moderate success in our first year with catch rates of up to 4 lb./ trap. Is there a fishery  for these crabs in Europe? Has there been any scientific research done on behaviour, reproduction,  or moulting? I would enjoy any response you could give me. Do you have any questions for me? Don't hesitate to ask. 
    Thank you for your time and consideration.

    Yes, we have full details of the requirements of the English Lobster, which are compiled are in the post to you. However, most of the information is from experience and not hard scientific facts. Therefore, we are still eager to hear of experiences from aquarists and workers at Public Aquaria? 
    e.g. Do lobsters thrive and moult in the smaller tanks OK? or do they do better in the large tanks?
    How much do they eat?

    Cotton Spinner   Holothuria forskali

    The puzzle is the Cotton-Spinner's defensive behaviour. When attacked, it is described as turning its rear end towards the threat and expelling a stream of long sticky white threads forcibly from the anus. 

    And any sea animal that is lifted from the water into air, whether by a rockpooler or in a dredge, will be extremely alarmed and distressed, so probably almost all Holothuria will eject threads in this situation. If I am right, until diving became common almost every Cotton-Spinner people saw had either been exposed by turning rocks on the shore or brought up in a dredge, and ejected its sticky threads in panic; so this was accepted as normal behaviour at any disturbance. 

    I have corresponded with one or two people about the Cotton-Spinner, but I would welcome any readers' observations which shed further light on these animals, whether confirming my speculations or not.

    I've been picking up dead Triggerfish, Balistes capriscus, up off the beach in Cornwall since 1991. I keep records of every fish I find, and I take most of them home with me, either to eat (they are always fresh) or to hang up to dry, their skin goes hard and leathery and they make good ornaments (outside). They wash in after Christmas when the sea temperature has dropped, in significant numbers (the most I found was 55 on Constantine Bay). My theory is that they can't take the drop in sea temperature, although they always wash in after! a storm and ground sea, so perhaps its the rough weather they find difficult?  By the way, they are also a common by-catch in lobster pots during the summer months.

    Notes on the sizes of  Homarus gammarus

    I have found an article on maximum size of lobsters. The biggest recorded in Norway was caught outside Bergen and weighted 5.3 kg. The biggest crushing claw of a lobster ever found was calculated to have been from a specimen that weighted about 9 kg. This claw was trawled up outside Denmark in 1964.

    Hello Andy, 

    I have looked up the article on Greenland Shark, Somniosus microcephalus, in National Geographic. The pictures were impressing. Do you know of any Public Aquaria who have kept Greenland Shark over some period of time? If this is done, how did the animal adept to the new environment, under which conditions was it kept, and for how long. The only one that I know of is "Havets hus" in Lysekil, Sweden. The specimen (who measured only 1,35 m) lasted only a few days before it died. Probably because of the wound it got when the local fisherman captured it. I am also interested in similar information on the Porbeagle, Lamna nasus, and a good picture of it in its natural habitat. It have lots of pictures of the Shortfin Mako, Isurus oxyrinchus, but I donít know about any of the Porbeagle.

    Dear Andy,

    Thanks very much for e-mailed stuff and 'Shorewatch'. I don't know if I told you before or not, but I operate a 12 metre passenger vessel  with UNDERWATER WINDOWS !! The only one in Britain. The vessel is brand new, and I have been taking people to see the Kelp beds round Kyle of Lochalsh since August.
    Since receiving Vol. 2, Issue 3 of Shorewatch it brought home to me how remiss I have been by not being in touch before. During the month of August we had a pair of Northern Bottle-nosed Whales in Broadford Bay, Isle of Skye.

    These were almost certainly immature animals as they were only 5.5 to 6
    metres long, adults can grow up to 9.5 metres. This species of whale was
    recently featured in the National Geographic (Aug or Sept issue). The whales
    created a  lot of interest, bringing people from all over the UK as they are
    very rare in inshore waters, they normally live off Nova Scotia, and north
    Atlantic waters. They are probably the deepest diving of all the whales with
    the ability to dive to over 1,500 metres and can allow over 1 hour between
    breaths. The whales were very active and breached regularly between 1 and 2
    hour periods. 
     
     

      Northern Bottle-nosed Whales, off Scotland       by Chris Hicks
       

    Giving spectacular displays, some of the pictures taken from my boat appeared in the national papers, you might have seen them ? The whales never appeared distressed, although at times they were in alarmingly shallow water, less than 5 metres. They always returned to deeper water if ever they got to close to the beach. At about week 3-4 we noticed the whales had lost weight and it was pity obvious they were not eating. In the last week their behaviour changed and they started to disappear for long periods
    underwater which I interpreted as hunting forays, I am sure hunger encouraged them to move until eventually they left the bay and headed North. Sorry I didn't have time to tell you about it before, as I work long hours and get home late. Incidentally we could observe them under water, as they would come right up to our underwater windows.

    Cheers for now,

    Hello Andy

    Two items in this months (September 1998) Angling Times:-

    1)  Two Porbeagles caught off north east Britain by commercial fishermen, the first
    was off  Sunderland by local boat 'Golden Lily' an estimated 420 lb shark about 3 miles out.  The next was an estimated 800 lb. monster (how big???) also caught by a local vessel the 'Kevally' also a Sunderland based boat. 
    Derek Booth who is general manager of  Wear Fish Ltd told AT: Large Porbeagles probably feature every three to four years and these were taken by boats driving for salmon, but none of this size.

    2) A very large Blue shark out of Looe in Cornwall the enormous shark estimated at 157 lb by the Shark Club formula as it was too big for the scales which jumped  at 150 to 160 lb.  At 8 feet 7 inches long and a girth of 37.5 inches was estimated at 157 lb a testimony to the shark formula chart accuracy.

    I'm trying to get confirmation and more details of both reports.

  • Portland Harbour
  • Summer 1998
  • 22 August 1998.
  • Dived yesterday on Countess of Erne  (Portland Harbour) (via Scuba Shack).

  • Other divers on wreck (first time I have dived it!) descended on bows and
    started towards stern.  Overtaking  other divers I suddenly realised I was
    looking at thin brownish lines dropping down holes so slowed down and then
    could spot individual fish hovering just above burrow.  Identification
    clinched by my daughter who had a torch and shone them into burrows when fish
    ascended towards light enabling me to see them clearly.    There is no doubt
    that they are Red Band Fish. 

    Interestingly in one book I read (Sea Life of Britain and Ireland pub. MCS and ed by Elizabeth Wood) it states that the Lundy population seemed to vanish for a few years and then reappear so how long this colony has been there would be interesting to know.  There is also a good 'full length' picture of one of these fish in that book.  The other friends diving with us also saw the fish and found that by hovering near by quietly they could watch them re emerge so re-breathers may not be necessary (but other divers kicking up the mud aren't!).  The mud around the burrows is dotted with sea pens of the slender variety (Virgularia mirabilis) - a night dive should show them luminescing according to the books.

         Red Band Fish
     

  • What is interesting is that Portland (at least) seems to shelter populations of deep water species.  A friend diving with Neil Garrick looking for sea horses found a population of sea pens on the harbour bed - a species normally associated with the  mud of Scottish sea lochs usually at significant depth (30m+).  I am sure that Simon saw Red band fish - they have been reported in Brixham Harbour which is even shallower. 
  • Look forward to hearing more!
  • Incidentally I was interested to see when diving under Ferrybridge (also Portland) yesterday that there were large numbers of Flabellina pedata again spawning i.e. much later in the year than when I last reported them doing this.  One or two female black faced blennies were also seen.  Out on the wreck of the Royal Adelaide earlier in the afternoon we saw two triggerfish plus a red gurnard when returning to the shore.
  • Finally I gather  from a written report seen when on a diving trip to Pembrokeshire recently that shoals of up to a 1000 Triggerfish individuals were seen diving a site known as Stack Rocks near Littlehaven in October last year!   For further information contact West Wales Divers, Hasguard Cross, Haverfordwest, Pembrokeshire.

    I have found no Pleurobrachia pileus "Sea Gooseberry" this year, there was a time when they would be washed ashore in their thousands. Their has also been a substantial decline in the number of Mackerel both inshore and out at sea. There have been no feeding frenzies that I have observed and Mackerel are becoming increasingly hard to catch.

  • description in "British Sea Fishes" I am fairly certain that they were Red Band Fish Cepola rubescens

    We saw approximately 8-10 fish free-swimming in a vertical position approx. 1 metre above the seabed, fully out of their burrows. When we approached they swam slowly backwards into the burrows in the soft mud sea bed. Approaching closer we could see 
    just the heads protruding above the mud, and as we swam overhead they retracted completely into the mud. We left the area but returned approx. 30 minutes later 
    when 4 or 5 individuals had re-emerged from the tunnels, and they then repeated their previous behaviour as we approached. 

    Water depth was approximately 15 metres, with reasonable water visibility allowing sunlight to filter through giving a lot of ambient light. The water temperature was approx. 17 ° and there was a very slight current. 

    There were a large number of other holes/burrows on the sea bed but we could see no evidence of fish in most of them.

    Is there anymore information available online about the fish?- the book that identified the fish that said that whilst they are common it is rare for them to be seen by divers since they tend to live in deep water. Another diver I spoke to said that they had seen the fish before but only at night, and it was unusual for them to be completely out of their burrows. 

    The fish were seen to the side of the wreck of the Countess of Earne (harbour side, not wall side) near the stern. However, whilst I have seen the burrows before this is the first time in probably 50-60 dives on the Countess that I have seen them. I tried to include as much information in the report as to the conditions, so hopefully if the conditions occur again it may make it more likely for them to be seen.

  • Hi Andy,
  • Rockpooling

  • When collecting specimens for my tank I have met some very nice people who are
    interested in what I tell them about my tank and the creatures in my bucket
    but unfortunately I also meet some either uncaring or plain stupid people
    who lift huge rocks and leave them there so the life on the rock will
    probably die. I have replaced many rocks to their original position only to
    find crushed crabs and small fish underneath. 

    Coastal Code

    However there are some nice intelligent people out their, about three weeks ago I was collecting specimens for my tank and saw a small bucket half filled with sand and some water filled with Poor Cod, I told the three young girls who owned the bucket that the fish would soon die due to lack of air and straight away they put the fish into the sea and also caught and returned the remaining fish from the rockpool. I was grateful for this and gave them a Blenny which I told them could survive in their bucket a little longer if they kept it in the shade.

    I also have a large anemone in the tank which is about 3-4 inches long and 1
    inch tall, it is red and its tentacles are all perspex and can suck in large
    pieces of food. I found the anemone buried in sand in a rockpool with only
    its tentacles protruding. I think it may be a Strawberry Anemone, any ideas?
    if you know what it is can you tell me what it feeds on.

    Probably a Dahlia Anemone, Urticina felina:   Andy Horton

    Cheers.

    During a dive today on the wreck of the Louis Sheid at Thurlestone in Devon I 
    was casually gazing at the carpets of Snakelocks anemones when it struck me 
    that some looked different.  Closer inspection showed a number of specimens to 
    have red bases to the tentacles, the red coloration tapering off towards the 
    tip of the tentacle. The red colour was only seen on the green variety with 
    purple tips and not all green ones were like this.  Is this is a well 
    recognised variant? 

    Yes, see Sue Daly's site:  Andy Horton

    Also have you any ideas as where I could find out about solitary hydroids. I 
    photographed a specimen 2 years ago in Lyme Bay and now wonder what it is - 
    although small it is similar to a much larger species found in Scotland.
