friends and i were in stuart in the
silver Silvester be fishing tournament
the oldest selfish fishing tournament in
the country second day we hooked on a
massive bluefin tuna and the only reason
we lost it was because was on a 20 pound
test leader line which a few fish you
know it’s not ideal for catching a
700-pound bluefin tuna one of the most
surprising things about the torrent was
that of the 54 boats they’re not one of
them besides us got a bluefin tuna bite
that’s how rare they are there’s no
doubt they’re so Erika’s humans have
over fished them for decades I will be
talking about the Atlantic bluefin tuna
one of the most beloved fish I fisherman
huge immediate away from 800 to 800 they
were from 800 850 pounds and are 60 feet
long they are silver and blue and are
used mostly to make sushi they have
dropped an astounding ninety percent
from the 1950s and in the 1940s and 50s
there were millions of them now there
are only hundreds of thousands in 1910
European countries barely recorded any
bluefin tuna landings but then 1915
manufacturers came out with new
high-tech fishing equipment and they’re
only 90 x rays fishing rods are made out
of a hundred percent would but then in
1915 they made steel fishing rods this
would allow fishermen got bigger fish
without losing them there are also urban
rifles a rifle which you’re harping deep
into the fish’s body they can’t lose all
strength and eventually die so it was an
easy point for the fishermen and because
of this and because of the advances in
technology in 1918 in the harbor of
Gothenburg Sweden they brought 8,000
bluefin tuna in one year it went from
barely no recordings to eight to eight
thousand that’s insane now if you’re
than 8,000 bluefin tuna are taken in a
year a sportfisher which is a type of
boat or the danish ion of animal in 1928
brought 62 bluefin tuna and one day and
the reason they could do this was
because of our boon rifle he and his
crew mates saw school of bluefin tuna i
took tarpon rifle and accumulated a lot
of them and because of the advanced into
technology in 1919 in 1949 the main
countries for fishing bluefin tuna
Roy Denmark soon in Germany Bryan 5,500
tons of bluefin tuna in the late 1940s
nor I had 43 boat today searching for
bluefin tuna I went to 200 votes a day
and because of this they were bringing
10,000 tons of bluefin tuna a year
because of the overfishing for the past
15 to 20 years in 1960 they bluefin tuna
or barely brought back to port and still
are today so far I have described the
overfishing of bluefin tuna but that was
not the point I wanted you to take away
I wanted to look and see other thousands
of animals facing extinction and we have
the power to destroy anything within a
short period of time because of the
advancements in technology and it’s okay
to kill two or three fish a day but not
62 in a day like an animal all the
animals that we slowly came off maybe
keystone species a keystone species is
often a dominant predator whose removal
allows the prey population to explode
often decreasing diversity we won’t know
if a bluefin tunas keystone species
until they go extinct because then we
will see the effect on our ecosystem and
this is the case with all the other
animals facing extinction and this will
slowly destroy our ecosystem I don’t
just affect efficient animals it will
affect humans too we need to stop the
Schreyer you go system right now and
treat our living things with respect
thank you [Applause]
