Narrator: HOP ON THE SHARK BUS,
MAKING ALL LOCAL STOPS.
TODAY, WE'VE GOT A MESSAGE IN THE BOTTLE

MY GREAT-GREAT-GREAT-GRANDPA ONCE SAID,
"IF YOU WANT ADVICE, PUT A MESSAGE IN A BOTTLE,
AND THROW THAT BOTTLE INTO THE SEA.
AND THEN YOU WAIT."
WELL, COME TO THINK OF IT, THAT'S ALL HE EVER SAID,
WAITING AROUND, SAYING THAT OVER AND OVER AGAIN.
WE WANT THE GOOD NEWS NOW!
HEY, CAP'N. GOT ANY ADVICE FOR US?
HUH?

WELL, I CAN'T EXACTLY TELL IF YOU'RE A MALE
OR A FEMALE, SO HERE'S MY ADVICE.
IF YOU'RE A GIRL, YOU NEED TO PULL OUT THAT VIBE,
GET SOME OF THOSE PHEROMONES IN THE WATER.
NO WAY THE GUYS ARE GONNA RESIST.
THEY'RE GONNA FLOCK TO YOU LIKE A GIRL
THAT JUST CHANGED HER FACEBOOK STATUS TO "IT'S COMPLICATED."
AND, IF YOU'RE A GUY, I SAY GET OUT THERE
AND YOU JUST TAKE A BITE OUT OF WHAT YOU WANT.
THAT'S HOW YOU LET HER KNOW YOU'RE INTERESTED.

THE PHILOSOPHER WITTGENSTEIN ONCE SAID,
"IF A LION COULD SPEAK, WE STILL COULDN'T UNDERSTAND HIM."
THAT PROBABLY APPLIES TO SHARKS, TOO.
I THINK, MAYBE.
I REALLY THOUGHT THIS WOULD WORK WHEN I STARTED IT.
I COULD UNDERSTAND THEM, BUT THAT'S ONLY BECAUSE
MY MIDDLE NAME'S AQUAMAN.

THIS IS A MILITARY UNDERWATER SPEAKER.
TYPICALLY, WITH ACOUSTIC ATTRACTION,
IT APPEALS TO TWO KEY SENSES IN THE SHARK --
BOTH THE INTERNAL EARS, WHICH THEY HAVE,
AND ALSO THE ABILITY TO PICK UP LOW-FREQUENCY VIBRATIONS,
WHICH THEY PICK UP DOWN THEIR LATERAL LINES.
Bussell: SO YOU'RE TELLING ME YOU'RE PULLING SHARKS
BY PLAYING MUSIC?
THIS COULD JUST BE OUR SECRET WEAPON.

Narrator: SHARKS FEEL SOUND THROUGH DETECTORS
THAT EXTEND ALONG THE BODY.
THIS GIVES THEM AN ACUTE SENSE OF WHERE
THE SOUND IS COMING FROM
AND ALLOWS THEM TO HONE IN ON THEIR PREY.
MATT BELIEVES THE BEST MUSIC TO ATTRACT BIG SHARKS
IS DEATH METAL.
ALL RIGHT. LET'S JUST TRY SOME DARKEST ERA.

IT WOULDN'T BE RIGHT FOR A SHOW

ALTHOUGH THE SHRIMP FISHERY HAS ONE OF THE HIGHEST RATES
OF BYCATCH OF ANY FISHERY,
IT'S ACTUALLY COME DOWN A LOT IN THE PAST 20, 30 YEARS
WITH PRODUCTION OF THESE NEW DEVICES
THAT ARE PUT INTO SHRIMP NETS.
THE FISHERMEN WERE REALLY HELPFUL
IN CREATING SOME OF THESE DEVICES
THAT WERE INITIALLY INTENDED TO EXCLUDE SEA TURTLES
FROM THE NETS, BUT ACTUALLY WORKED TO HELP
KEEP A LOT OF LARGE ANIMALS OUT OF THE NETS,
SUCH AS SHARKS AND RAYS,
SEA TURTLES, AND OTHER LARGE MARINE ANIMALS
OR OTHER LARGE FISH.
I TEACH A LOT OF UNDERGRADUATE
AND GRADUATE STUDENTS WITH MY JOB,
AND A LOT OF THEM ARE INTERESTED IN CONSERVATION WORK.
SO THE WORK THAT I'M DOING WITH MY GRADUATE STUDENT
WITH THE SHRIMP TRAWLS REALLY BRINGS IN
A LOT OF POTENTIAL TO TEACH THESE NEW STUDENTS THAT --
