the way that I have.

One of my more recent stories
in the magazine; in March of this year
the magazine published a story that I photographed about
Bluefin Tuna.
This is a picture that I made in the Mediterranean
off of Spain where Bluefin are caught
in giant purse seine nets.
Methods of catching tuna like this
have been very destructive.
They have actually resulted in the collapse of tuna stocks
in the Mediterranean and throughout the Atlantic…
with populations being decimated.
And this is an image that I made at the daily tuna auction
at the Tsukiji fish market in Tokyo.
Every single morning
the tuna bodies are lined up like cordwood and
auctioned off to the highest bidder.
It’s really the lust for sushi
that has created this.
You know, I live in New England and
I’ve been on the water most of my life.
And I can remember back in the early 70’s,
fishermen catching Bluefin Tuna
and there was no market for them.
They used to call them horse-mackerel.
They considered them trash fish and
would bury them on the beach if they caught one.
There was really nothing for them but once that…
that sushi craze sort of took place and began,
the prices skyrocketed and all of a sudden
the stocks began to plummet.
But this is what happens, you know,
every single day. We can’t sustain this kind of thing.
This animal now has become the most valuable
animal on the planet. A single Bluefin
has sold for over a million dollars at this–
these auctions in Tokyo.
So you can imagine with a bounty like that on their head
the future is probably not very bright.
There’s actually three species of Bluefin
but we were focusing on the biggest and,
and sort of most magnificent, the Atlantic Bluefin Tuna.
It’s an animal that’s quite unlike any other.
You know, these are animals that continue to grow
their entire lives. If weren’t so efficient
at catching them there would be 30-year old
Bluefin out there that weigh a ton.
These are animals that are capable of generating heat
in their body. They are effectively a warm-blooded fish.
And because of that they can swim
practically from the equator to the poles
in search of their prey.
They criss-cross entire oceans
in the course of the year. There’s no predator on land
that covers that kind of territory.
Um… you know, they are truly amazing fish.
But to find Bluefin in the wild,
I had to travel to a place where they are hunted.
And this time it was the Gulf of St. Lawrence in Canada.
And I would probably rather not see them caught at all,
but in small ports,
in Nova Scotia and Prince Edward Island
fishermen head out during their season
for just a very brief time
and they use only a rod and a reel
to catch one fish at a time.
The season is very brief.
When I was up there it only lasted for about a day.
They have extended it now a little bit longer
but it’s still the same quota,
which is very low.
And it’s essentially one man,
one fish.
As soon as they are caught they are processed on the dock,
iced and shipped off to Japan.
And in those weeks before the fishing season begins
researchers also come here
to tag Bluefin. They are trying to do science,
trying to look at their migrations, where they go
and where they migrate to and from.
And they work with local fishermen as we see here
who’ll catch the fish.
When they hook up on a giant Bluefin sometimes it takes,
you know, close to two hours to reel one in
and get it close to the boat.
And they’ve worked with a variety of tags
to put on these animals.
But the most effective or the most productive
over these years has been satellite tags.
They can tag the animal
and it can stay on for many months and then it pops off,
sends up a signal where they can retrieve it
and download the data
and see exactly where this tuna has migrated to.
And it’s been very valuable as a conservation tool.
And once they
catch the tuna, after maybe a two-hour fight,
they get it close to the boat
and then they have to get it up on deck very quickly
and do the science and work it up.
One of the researchers,
his job is the lip-hooker,
where he uses this big sort of metal hook
to go through the bottom jaw,
which is the strongest
and then they very quickly get it up on the boat
and try to do up their…
their science here.
You can see the captain of the boat is aerating the fish,
he is putting water inside to aerate the gills,
keep it alive
and they are measuring it,
both length and girth.
They are taking pictures of the animal,
they are taking a DNA sample, blood,
all happens usually in about a minute.
It’s amazing how well they work.
So this was a GoPro video that
we did that just shows how this all happens very quickly.
So they measured as I said,
and you can see the size of these animals.
It’s not the best with some shadows here,
but you do get a sense of the massive beast
that this Bluefin is.
So, within, you know, 60 or 70 seconds
the fish is back into the water
and swimming off with that tag inside of it.
I also wanted to show another fishery for Bluefin.
One that happens on the other side of the Atlantic.
And this is one that actually dates back
thousands of years.
This is a view of a place called Barbate, Spain.
A little town in the Atlantic on the
southern coast of Spain
and it’s one of many locations
that has done this very
old method of catching Bluefin for centuries.
It’s a method called the
Almadraba Fishery.
There used to be many of these places.
Today there is just a handful left
and Barbate is one of them.
But what they do is they use a series of nets
to sort of passively catch the tuna
as they are migrating
from the Atlantic through the, uh…
Gibraltar Straits into the Mediterranean
and they get caught in this net.
There’s sort of a line in the ocean there,
those are a line of buoys.
And those are the buoys,
those are the nets, so it’s quite close to shore
that this all happens.
The way it works is the fish
once they hit the tail of that net
they move through a series of chambers,
a series of rooms,
different nets and when they have
enough tuna in the final chamber,
the “cámara de muerte”, the chamber of death,
they sort of close it off
and then they begin lifting up the bottom
and they hold what’s known as a “matanza”,
the massacre.
And, here we see that very thing happening.
These fishermen use these old wooden boats
and they form a square around that last chamber
and then they slowly begin muscling up those nets
and the tuna, you know
begin thrashing in very shallow waters.
We see a Bluefin right up here
swimming right up on the surface, almost full body
out of the water.
And then once they get the sort of tuna up there,
they hook them and bring them on this one boat
where they immediately bleed them
and begin processing them and…
You know, having swam with Bluefin underwater
it’s always a little difficult for me to see
this kind of thing. And I understand
what they are doing and it’s a way of life.
But in some ways for me it was like
seeing a crime unfold, you know.
I had such reverence for these animals.
I’ve always sort of wished
that I could take these folks underwater,
very few of them dive.
But I always wished I could take them underwater
to see Bluefin within its own element
and I have to believe it would change their mindset.
To be underwater with these magnificent animals
is to witness the divine sense of nature.
They are the true thoroughbreds of the sea
with few if any equals.
With streamline design that’s been
studied by naval engineers,
they swim faster than a torpedo.
And likely posses physical endurance
that we can hardly fathom.
How I wish everyone
saw Bluefin Tuna the way that I have.
For being underwater with them
I know of their greatness and I am certain
they posses abilities and hold secrets
we can barely imagine.
Thanks very much.
