Endangered shark washes up dead |
31st July 2007
Far
from striking fear into the hearts of holiday makers, a dead,
juvenile porbeagle shark met with sympathy and interest at Gunwalloe
on the Lizard, where it washed ashore this weekend. Families
gathered around to look at the stricken shark and many commented on
how fascinating it was to see one. However, they also expressed
great sadness to see that it had died and were keen to know the
cause of its death.
Following the hysteria that certain media coverage of the
supposed great white sightings created over the weekend, it is
reassuring that people on the beach showed no signs of fear at the
sight of the dead shark. People were still surfing and swimming and
didn't seem at all concerned - and rightly so.
Jeff
Loveridge, who recorded the fish for Cornwall Wildlife Trust’s
Marine Strandings Network said, "The
children were particularly interested and appreciated how lucky they
were to get up close and personal with such a rare shark, but many
said how sad it was to see it dead. We were really grateful to the
holiday makers that helped us carry it - and to the chap who helped
confirm the species: he just happened to have a shark reference book
with him at the time."
Jan Loveridge of the Trust’s Marine Strandings network commented,
"When the Kerrier Lifeguards called us
out, we expected to find a small dogfish, so it was a bit of a shock
to encounter this fantastic shark. At this time of year it is common
for stranded basking sharks to be reported, but this is the first
time we’ve received a call about a porbeagle."
Caroline Curtis, a volunteer who helped record the shark said,
"This young shark was only 1.5m long and
looked as if it had died very recently. Sadly we found what
resembles rope marks around the shark’s body, indicating that it may
have died as a result of being caught in fishing gear."
Joana Doyle, Marine Conservation Officer for the Trust added,
"The porbeagle, which is one of the
species of shark most often confused for being a great white, does
not pose any threat to humans. In fact, it is us that threaten their
survival. Porbeagle sharks are now critically endangered in the
Northeast Atlantic due to overexploitation for their meat and from
being accidentally caught in fishing nets."
"Sharks are fascinating creatures and most are under severe
threat due to over-fishing. It would make a refreshing change to see
the media help us promote shark conservation, rather than focusing
on these apparent great white sightings which are guaranteed to hit
the papers each year, leaving many people unnecessarily terrified of
getting in the sea."
The porbeagle can grow to around 3.5m (about 12 ft), weigh over
230kg (500lbs) and live up to 30 years. Low reproductive capacity
and high commercial value of the meat makes this species highly
vulnerable to over-exploitation and population depletion.
It is important that members of the public call the Trust’s
24-hour Marine Strandings Hotline on 0845 201 2626 if they ever come
across a dead marine animal. This means that volunteers can then
record important information about the animals and take samples.
Samples were taken from the porbeagle for the National Marine
Aquarium in Plymouth, who is currently undertaking research into all
species of shark. The Trust will also share the data with the Shark
Trust, who work hard to promote shark conservation.
