in the 60's and 70's that collapsed
under very heavy fishing pressure

by and
it has not come back,

thirty years it
has not come back

Sole and the are
fully exploited and

could not really sustain
and further fishing pressure,

the also is
fully exploited,

there is no room for expansion

Now with so much fishing pressure
in surface waters

fishermen are going deeper and
deeper to find fish for the market,

we've seeing things here that

we would never even have
heard of twenty years ago

This is a black scarvered and
it lives at about a thousand metres

So are these fish in trouble?
lt's hard to say really...

...because like everything else
that lives in the deep

very little is known about it
and that's the problem

with deep sea fishing,
the scientists don't really know

what's going on down there

and they're only just
beginning to find out

Scientist from are
now using cameras

mounted on to study the
effects of fishing on the deep sea

Only in the last thirty years have
we had the technology to fish the deep,

But in many places the fishing
pressure has been very intense

This particular fish
is now on our menu

These white fish are the of
a deep sea fish called orange ,

you may have noticed them at your
local or supermarket recently,

they can live in up to depths of
one thousand five hundred metres

and like a lot of deep sea fish
they live a very long time

These ones could have been born
during world war two,

they could even have been around
during the Victorian era

lt's believed that orange
can live to a

one hundred and fifty years old

But as well as living longer
these fish mature later

at about thirty to
thirty-five years old

you take them out before this age
they won't be able ,

there won't be a future
generation of orange

For many years the fishing
pressure here was huge,

thousands of tons were for
the market and sold around the world

At times so many were
caught there wasn't even

the market for them,
they were just dumped

Fortunately the New Zealand
and Australian

recognised the problem in time and now
they monitor the fish stocks carefully

The fish may be safe but
the habitat they rely on isn't

the deep sea there are
animals that are so new to us,

and so strange that it's as
if we're in another world

Despite it's
the deep sea habitat

is now under threat,
and once again

lt's the method of fishing
that is causing the real damage

Deep sea fishing nets are huge,
they life...

and hundreds
of years old

are being the sea
bed ...and destroyed

What actually does,
particularly in the deep sea,

...where fishing nets is actually
concentrated around sea mounts

which is very hard rock,
to protect the net from the rock,

they've got huge steel
balls on them,

and those balls are about
half a meter in diameter

and they run along on
a huge ground rope,

now that net is pulled
along at say three

into the rock,
, ,

, , ,
Smack, Smack,

So this net basically comes along
and it physically that thing down,

just , shoots it
into the back of the net,

it's history, it's dead, it's got
no chance of living after that

You can't see the
damage done at depth

but if the same was done on land,
you'd be .

if we wanted to catch
cows for instance,

we'd get a net and hang it from
a helicopter and we

...drag that through the ,
we would not only catch a few cows,

we'd catch the dog, we'd catch the car,
we'd catch the , the barn,

we'd catch the farmer's wife,
we'd catch all this other stuff

that we weren't
originally going for

O'hea is concerned about
many of the animals

that have been brought up from
the deep most of them

He's monitoring the
damage being done,

From his lab in New Zealand.

One of the most spectacular
things we...
