Today has been a
huge success. And Javier’s birthday, too. We started with somewhat
ambitious goals and we have achieved the lot of them without a
hitch!!! We are done with the region of our study area that we call
3O, which is a bit boring because there is little fish, there are few
trawlable places in the deeper strata and we do not have the bottom
cartography. IN 3O there are 22 hauls and we have finish them today.
Yes!! So far we have bagged 33 hauls, 32 of them done in 5 days,
which is very, very good going. Surely former Platuxa participants
will choke the commentaries section tomorrow with messages to confirm
this.

We started with a
haul at 1300 m at 6 this morning and we hauled the sixth and last
haul a mere two hours ago at about 350 m. We have also taken two
profiles with the CTD and right now we are about to take the third.
The weather has been exactly as we asked the meteorologists for
-thanks, guys, and lots more, but let’s go step by step...

Starting at 6 in the
morning is not just because, but a need to optimise working time. If
we wouldn’t do this the team starting at 8 would have nothing to
do until 10, and we cannot afford that. We got lots to do, too little
time to do it and we are constantly under threat of a low forcing us
to stop working and shaking us on top of it.
The catch in the
first haul was very scarce but brought some Greenland halibut,
different grenadier species, chimaeras (we will show them very soon),
but mostly antimoras, which I dislike quite a lot. The second haul
was equally poor but came with a surprise: a Linophryne lucifer
right under 20 cm that arrived
in very good condition even though they are so soft, and she had a
male attached to her!!!! These are anglerfish, and as such, instead
of a dorsal fin they have a single spine that leans forward and has a
photophore dangling from it. This organ produces light that attracts
unsuspecting prey. Where they live (we got this at 1000 m), the only
light sources are living organisms. Light can mean finding a mate or
becoming a meal. More on this on a very entertaining book by Palumbi
&
Palumbi called “The
extreme life of the sea”. I
have also found an smashing comic on the private life of these fish
that I strongly recommend: http://theoatmeal.com/comics/angler
It
so happens that males are tiny but have a very well developed….
sense of smell, which they use to find the enormous females. I don’t
know if it is hunger or not knowing what to do, but when they find a
female they start to bite her. As they bite, their mouths melt into
her body, so they become attached to her whether they want it or not.
Next step is that their whole bodies melt into the female’s, until
only the gonads can be seen. These will be used by the female when
she sees fit, and she can have several males thus attached. So.

After
this, the next haul at 800 m was a bit disappointing, with more
antimoras, a few dogfish and little else, but lunch came with a
birthday cake and we forgot about the haul in no time.
And
then, surprise, surprise!!! Fourth haul, right before the codend
arrived, a sperm whale showed up!!! I love them. Don’t know if it
is because I have seen so few of them, because they are so weird,
with that enormous head that takes one third of their bodies. Their
heads hold the spermaceti organ, which liquefies when they surface
and hardens when they dive. But besides being a flotation aid, it
seems it can also act as a ecolocation organ. The photos are not
contest winning, it was so close that the cranes at the stern were
always in the frame.

After
this Jose María came with this mad idea of chucking his GoPro down
the fish hold to film the process from a fish point of view…
everything we can say now is that we need to develop this further.
The GoPro survived.
When
it seemed the day could offer no more, the fifth haul came WITH
ANOTHER SPERM WHALE in its wake!! Or maybe it was the same? It also
loitered a bit about while we hauled the gear. But we had to leave it
behind to go for our last haul. Besides, we had caught an Atlantic
halibut that measured 153 cm and weighted 44 kg!!!! That’s nearly
as big as I am… Ole Venicio and Edu for lifting it for the pic!!!

Luckily
by then was dinner time, I was starving after going upstairs and
downstairs a million times (four decks from the bridge to the working
deck). Delicious cod from yesterday, among other things, because the
kitchen on board Vizconde is
not from this world.
Time
to haul the sixth and last haul, with Adriana, Iñaki, Marta and
Nair, I go downstairs, purposedly leaving the camera behind because
what else could happen today? Well, it could happen that in the last
haul you catch a 117 cm and 28 kg anglerfish, thank you very much!
Iñaki, despite his own size had trouble to take it, difficult to get
a hold on an anglerfish of that size, with all those teeth and so
slimy….
So,
as you can see, no way to get bored here… Thankfully we will start
tomorrow at 5:30, otherwise the day would not be long enough… Off
to bed, the lot of you!!
