| When you think whales
and dolphins, does your mind conjure up images of tropical
destinations and turquoise seas? If so, you’re not alone.
Many people are surprised to hear that of the 80 or so species
of whales, dolphins and porpoises (collectively known as cetaceans)
found worldwide, an incredible 28 are found in UK waters.
Populations of three of these species, the Bottlenose dolphin,
the Harbour porpoise and the relatively little-known Risso’s
dolphin, can be spotted close to the coast. Bottlenose dolphins,
in particular, can regularly be sighted at certain points
around the UK with resident populations in both Scotland’s
Moray Firth and Cardigan Bay, West Wales. Each has been estimated
to contain approximately 130 animals, many of which have distinct
marks and can be individually recognised. A third, more nomadic
population, lives off the southwest shores of England.
Whale and dolphin watching is phenomenally popular worldwide.
In the Moray Firth, the dolphins often visit the area close
to the Wildlife Centre in Spey Bay to feed and can be sighted
both from land and by boat. It is important to remember, however,
that dolphins can be disturbed by boats, especially if driven
carelessly. If you take a dolphin-watching trip in the Moray
Firth, please use a DOLPHIN SPACE PROGRAMME registered operator
who will have agreed to behave responsibly around the dolphins.
Occasionally, species such as the magnificent Orca (killer
whale) come close to shore but are mainly seen in offshore
waters, as are a number of other species. These include ‘great’
whales, such as migratory Humpbacks on their way to or from
feeding grounds in northern waters and smaller oceanic dolphins
such as Common and Striped dolphins. Species such as the Blue
whale – the largest of the UK’s cetaceans and,
indeed, the largest animal on Earth – are increasingly
being identified in UK waters and, alongside Fin and Sei whales,
are probably breeding here too.
Sadly, in UK waters, as elsewhere, cetaceans face a number
of threats to their survival, including bycatch (accidental
capture in fishing nets), marine litter, chemical and noise
pollution, and other forms of habitat degradation.
Research has shown that the population of Bottlenose dolphins
in the Moray Firth is decreasing. Unless something can be
done to halt the current rate of decline, we expect them to
be no longer viable in just 45 years. There are concerns that
they are being subjected to considerable stress and some individual
dolphins also seem very heavily diseased.
Harbour porpoises used to be regularly known as Common porpoises,
but now appear to be virtually extinct on the south coast
and in the southern North Sea. In the Celtic Sea bottom-set
gill nets are calculated to be removing some 6% of the local
population per year and this rate of loss cannot be sustained.
Recent legislation such as the 2000 Countryside and Rights
of Way (CRoW) Bill is a step in the right direction for cetacean
protection around the UK, as it treats reckless disturbance
of cetaceans as if it was intentional – but there is
always more that can be done and everybody can play their
part by taking a few simple steps:
-
If you see dolphins or whales being chased or disturbed,
report it to the police – it is an offence!
-
Take care to dispose of all waste, including oil, appropriately.
Most marinas and ports now have facilities for the safe
disposal of boat waste.
-
If you are going to the seaside, leave any excess packaging
at home and take care to collect and contain all your
rubbish.
-
Dispose of all fishing equipment with care. Nets, hooks,
lines or other fishing equipment can go on killing if
discarded or lost in the sea.
-
Above all, help raise awareness of the UK’s cetaceans
by taking part in WDCS’s Active Seas Programme!
