lts only in the last fifty years
with the invention of the aqua lung

that we've been able to
enter the under world

and see some of the extraordinary
animals that live there

Dolphins are the playful
popular face of the ocean

but most of what lies below the surface
is out of sight and so out of mind

Even the twenty odd years
that l've been diving there

have been big changes in our seas

lt's clear that our oceans
are now in real danger

Flying over miles and miles
of ocean you get the impression

that things aren't too bad

But below the surface there is
a multitude of man made problems

Of all of them, probably the
most destructive is fishing

and it's the way we catch fish
that's the problem

Blue fin tuna, king of the sea,

they are exquisitely designed
for the open ocean.

They can grow to three
quarters of a ton

and can swim at fifty
miles per hour,

faster than any other creature
in the sea, part from us

They have few natural predators
when fully grown,

yet it's believed that these
blue fins are now endangered

There's no place in the Ocean
where we can't peruse them,

they just can't escape us

Fishing has become
incredibly high tech

So much so that we can
pretty much capture anything

anywhere in the world nowadays

These blue fin tuna boats
beneath me have every

mod con they have
incredibly big engines,

they're using depth sounders, DBS's,

they've even got spotter planes
in the air spotting the fish for them

Yeah well, there are about eight
fish over here that just went down,

they're on my left side

So the blue fin tuna travelling
at fifteen miles an hour,

Haven't really got much
of a chance the moment

it comes to the surface
somebody's going to spot it

Come left, yep there you go,
twelve o'clock, five to six boats

Here they are being hunted on one
of their major migration routes

lt's thought they swim
from the gulf of Mexico

up the eastern seaboard of the
United States to Canada each Summer

Their routes are so predictable that
fishermen can catch them year after year

While these fishermen
are still catching them,

there are scientists who
are tagging the fish

Trying to discover how many
separate populations there are,

what their movements are and
just how many fish are left

Marine scientist and keen
sports fisherman Carl Safina

fishes off Long lsland, New York

He loves fishing for blue fin but
these days he has to target other species

l've been fishing off shore since
l was twelve with my fathers and my uncles

and we used to see lots
of blue fin tuna,

a lot of small ones
and a lot of big ones

Now, err, there are so few tuna,
that people more fish for sharks now

Safina is so concerned by the
decline in numbers that

He's started a campaign with
the national Audubon society

to try and save these tuna

What we do know is that blue fins
in err the western part of the Atlantic,

in other words the part of the
Atlantic off the US and Canada

is that err from the
mid 1 970's seventies

%

ln New England where most
of the western Atlantic blue fin

are caught commercially fishermen just
don't believe these government figures,

they claim there are consistent
mistakes in the analysis,

so they are naturally
very sceptical

about the quotas the
government imposes on them

Scientific research in
the ocean is extensive

and the politics surrounding
this fish are complicated

But one thing that
is indisputable,

these fish sell for
vast amounts of money

The blue fin tuna was
worth err a few cents a pound

and often sold as cat food
until some people realised that
