Note: Any further information on Gobius couchii would be of interest to me=
=2E I am not sure it is a good species. It is very close to the very common=

RECOMMENDED BOOKLIST 1995
1. Handbook of the Marine Fauna of North-West Europe.
Edited by P J Hayward & J S Ryland.
Oxford University Press 1995.
ISBN 0 19 854054 X (Hbk)
ISBN 0 19 854055 8 (Pbk)
This is the definitive handbook guide for the experienced rockpooler and ma=
rine biologist. It should be on your shelf and on the shelf of every Public=
Library. There is comprehensive and up to date identification of all inver=
tebrate species likely to be seen in the seas around the British Isles. Fis=
hermen will need a further book as the fish list omits some open water fish=
=2E Marine mammals are excluded. Excellent line drawings only.
Paperback price =9C29.50.=20
2. Marine Wildlife of Atlantic Europe
by Amanda Young, photographs by Paul Kay.
Immel Publishing 1994 (not actually published until 1995)
ISBN 0 907151 81 7
=20
This is an excellent book with splendid colour photographs of many of the c=
ommon animals and seaweeds likely to seen by rockpoolers, divers and casual=
visitors to the coast. It is not a comprehensive identification manual but=
rather a book that describes the behaviour and appearance of the inhabitan=
ts of the marine world around the British Isles. Recommended.
3. Animals of sandy shores
by Peter J Hayward
Naturalists' Handbooks 21 Richmond Publishing Co. 1994.
ISBN 0 85546 293 0 Paper
ISBN 0 85546 294 9 Hardcover
An extremely detailed study of the characteristics and ecology of a sandy s=
hore and the animals that live for the most part buried in the sand. This i=
s not an easy read for the novice rockpooler but should appeal to the serio=
us student of the seashore. Recommended. There is another good in the serie=
s Animals on Seaweeds by the same author.
4. A Field Guide to the Nudibranch of the British Isles
by Bernard E Picton & Christine C Morrow.
Immel Publishing 1994
ISBN 1 898162 05 0
This is both a comprehensive guide and a descriptive guide to the true sea =
slugs, the order of gastropod molluscs called the Nudibranchia that have co=
mpletely lost their shells. Each species of these colourful animals has bee=
n excellently photographed. It should appeal to divers and rockpoolers. The=
re are a few animals that are sometimes called sea-slugs like the Sea Hare =
which still retains part of its shell. These belong to a separate order cal=
led the Anaspidea that are not nudibranchs and are not included. There are =
no anatomical line drawings. Recommended.
5. Guide to the Identification of Whales, Dolphins and Porpoises in=20
European Seas
by Peter G H Evans
Sea Watch Foundation Publication 1995
ISBN 1 85716 193 9
This is a very useful little booklet to identify the cetaceans that can be =
seen in the seas around the British Isles, with colour photographs of all t=
he common species that you should enable to identify each species if you ca=
n get close enough in fine weather. There is a list of addresses and furthe=
r reading.
6. Marine Aquarium Keeping
by Stephen Spotte
John Wiley & Sons 1993
ISBN 0 471 59489 X
Although described as a no-frills, no-nonsense book for beginners, it is no=
t the best book for those starting up in the hobby of marine fishkeeping. H=
owever, for advanced marine aquarists its straightforward style and sensibl=
e ordered explanations put it in a class of its own ahead of any other book=
on the subject. Essential reading.
7. The Care & Management of Decapod Crustaceans in Captivity
by R W Ingle
Universities Federation for Animal Welfare 1995
ISBN 0 900767 86 3
Decapod crustaceans, prawns, crabs, lobsters etc. are often kept by aquaris=
ts. They are not too difficult to keep, but species have their own particul=
ar requirements. Ray Ingle is an expert on British crabs. Aquarium manageme=
nt is very much in the style of Stephen Spotte. Aspects of crustacean biolo=
gy are included. This is a compilation of information published elsewhere,=
but if you want it all in one book it is a good buy. Extensive bibliograph=
y. There is a UFAW Handbook on Cephalopods in the same series.
8. Sea Bass. Biology, exploitation and conservation.
by Graham D Pickett and Michael G Pawson
Chapman & Hall 1994 Fish & Fisheries 12
ISBN 0 412 40090 1
Of interest to anglers and fish biologists in southern England, this book e=
xamines the biology and its connection with commercial and recreational fis=
hing, with a few notes on Bass behaviour in aquaria.
9. Secrets of the Seashore
Various authors
Hodder Stoughton. Reader's Digest 1984 reprinted 1989
ISBN 0 276 37436 3
This book first published in the last decade still represents a good value =

THE BRACKISH-WATER FAUNA OF
NORTHWESTERN EUROPE
by R.S.K. Barnes
[Cambridge University Press 1994]
ISBN 0 521 45529 4 (hc) =9C40.00
ISBN 0 521 45556 1 (pb) =9C15.95.
Books on brackish-water fauna never seem to fall within the province of the=
fresh water biologist or the marine biologist, hence the need for this boo=
k packed with information about physical characteristics, the ecology and t=
he flora and fauna of the variety of brackish water habitats in northwester=
n Europe.
The book is divided into two parts.
Part 1 is called Brackish-water biology and starts with an interesting acco=
unt of the origins of brackish-water habitats, which in itself is good enou=
gh reason for having a look at the book.=20
Part 2 is an identification guide to the animal species found in brackish-w=
ater habitats. The list is so comprehensive and thorough that the student w=
ill not have to resort to both a guide to marine species and one on fresh w=
ater.=20
This list includes the recommended books published in 1995. A separate list=
will be included for 1996 in the December 1996 'Torpedo' and will include =
other books published in 1995 that were omitted from the above list because=
they were not received in time.
OPISTHOBRANCH MOLLUSCA
All opisthobranch molluscs have been found to be under-recorded from shore =
and sub-littoral habitats. It is easy to understand why. Most species are v=
ery small, and despite their bright colouring they are cryptically disguise=
d to match their prey of seaweeds or hydroids on which they spend most of t=
heir lives.
Rockpoolers and divers are in an unique position to rectify this shortfall =
in the knowledge of the distribution of all sea hares and sea slugs. All si=
ghtings should be sent in with as many details as possible, including any p=
roblems in identification, size, feeding plants, whether spawn is present a=
nd as many details of the location as possible. Special forms are available=
=2E It is also important to mention if the sighting has already been record=
ed to another authority to avoid duplication in the national records.=20
Nudibranchia
An extract only is included of the Nudibranch records. Please request the c=
omplete file that runs to 1500 words.

Triggerfish Balistes capriscus
Reports 1996
Triggerfish were reported much later in the summer than 1995. At Mevagissey=
in south Cornwall, the first captures are usually made in spring, but the =
first one did not arrive until near the end of August (24th), when a fish o=
f 1 kilo was captured in a crab pot and brought in to the Aquarium. The sea=
temperature was about 2=F8C down on 1995.=20
Chris Gilbertson
Dorset Fish
The first Triggerfish off Chesil Beach, Dorset was first sighted by divers =
on 15 August 1996. with a further 16 spotted on 1 September.=20
On Saturday 7 September on a night dive to the Royal Adelaide, 15 Triggerfi=
sh were seen in 11 metres of water off Chesil Beach away from the wreck and=
were laying on their sides, apparently asleep. What was unusual was that t=
he dorsal spine of all of them was erect, one can only assume this was a de=
fensive postures.
Ken Gollop of Lyme Regis Aquarium has had several reports of Triggerfish be=
ing brought to the surface in crab and lobster pots from the Lyme area.=20
