Dolphins
and Porpoises
The
Scottish Natural Heritage, in 1999, published a report predicting
that the Moray Firth dolphins could disappear within 45 years.
First
recorded in 1898, these 129 bottle-nosed dolphins are virtually
the same as the ones we associate with the warmer waters of Florida,
USA.
There
are two populations in Britain, the other being in Cardigan Bay
in Wales.
It was distressing for me to learn that for some, as yet unknown
reason, 95% of the Moray Firth dolphins are suffering from skin
lesions, mushroom type growths, patches and swellings.
Unless
something can be done, the future doesn't look good for these graceful
creatures.
Many
residents of the central belts of Scotland travel to other parts
of the country to visit relatives or on holiday. For people who
don't live by the sea, it is sometimes a surprise when they notice
porpoises and dolphins in our coastal waters.
They are especially prominent along the west coast, where the most
common species is the Harbour Porpoise, but this is pushed hard
by the Bottle-nosed dolphins, which are quite plentiful around the
Isle of Mull.
Another group of dolphins inhabit the coastal waters of the Isle
of Isla and, on mainland Argyll, the waters near Crinan have recently
become another bottle-nosed dolphin hotspot.
The
Hebridean Whale and Dolphin Trust has been collating a photographic
catalogue of these various resident bottle-nosed dolphin groups
for the past three years. They are trying to identify individual
dolphins and monitor their movements.
Any readers with photographs they would like to contribute to this
catalogue should send them to the:
Hebridean Whale and Dolphin Trust, 28 Main Street, Tobermory, Isle
of Mull, PA75 6NU. Tel: 01688-302620
Any
dolphin sightings in the west of Scotland waters should be sent
to the above address.
