Monster Fish, Part 2: Mongolia’s Cannibal Trout | Nat Geo Live


a few years into the project we also
started doing a television show called
monster fish that we’ve been doing for
six seasons now so now I’d like to share
a few stories from from the project and
also some clips from the shows like to
tell you about eels longfin eels the
longest freshwater fish in New Zealand
they make these epic migrations they are
born in the ocean and then they find
their way into streams and lakes in New
Zealand live for sometimes over a
hundred years
seals are actually the slowest growing
or one of the slowest growing of any
fish but they live so long that they
still reach lengths of seven or eight
feet so it was my job to swim down to
see if I could find one of these big
eight-foot eels there goes nothing
ha ha ha he looks their whole
surrounding suddenly I realize they’re
not dangerous at all
they are some of the most curious
predators I’ve ever seen
next I want to tell a story about the
world’s largest trout and it’s a story
of a partnership this is a the world’s
largest trout it gets six feet long 200
pounds
this fish is endangered its disappeared
from China most of China it’s
disappeared from a lot of Russia but it
still has a few healthy populations in
Mongolia and this photo was taken in
Mongolia and this is a photo of a 5-foot
Timon that swallowed a 3-foot Timon and
choked to death and then in the 3-foot
time in its mouth there was a one-foot
Timon so I don’t maybe that’s why
they’re endangered
right there it can’t help themselves I
don’t know how many people I know there
are a few people not answered have been
to Mongolia but you think of Mongolia
maybe you think camels you think Gobi
Desert but there are places in Mongolia
that are lush beautiful green and these
are the places where the trout the Timon
lives and this is the place where we had
our project our project was a
partnership between local people
recreational anglers and scientists as
scientists we would go out and the
fishermen would catch the fish we would
get our data and it worked really well
we had this project for five years we’re
able to collect a lot of good
information and partially as a result of
this project the Mongolian government
decided to make all fishing for Timon
and Mongolia catch and release so now
there’s no more harvest time and they’re
all released after they’re caught and we
also found a valuable information about
these fishes age their growth their
movement patterns these timing can live
to be over 50 years old and we found
that their movement patterns they would
move to the same place the exact same
place in the river year after year and
so sometimes you don’t think about that
I certainly didn’t think about it before
this project that you could be fishing
and catch a big fish that has been
sitting in that spot where you caught it
for 50 years that’s pretty incredible
