Let’s do something special because it is Friday, and upload a
video by Bernardo Pérez, from IEO Santander. Bernardo took part in the survey
in 2014 and hopefully we will see him again on board, for many reasons. One of
them is that he makes very nice videos, as you can see. He put in a fair amount
of work.
For those not familiar with fishing follows a brief
description of the footage, which shows how is the gear shot, seen from several
angles. Bernardo took several videos and edited them to make this clip.
The video starts with the gear on deck. You can see very well
the rockhopper, or line with black bobbins that roll over the seabed,
separating the net from the substrate. The floats line is attached to the top
panel at the mouth of the net, and helps to keep it open.
Soon you see the deckhands taking their places. The mobile
door goes down and a whinch is used to
shoot the net overboard down the ramp. The foreman takes his place on deck
between the flotas to make sure that the net wings do not get entangled as they
unwind from the net drum.
Once the net is in the water, the mobile door goes up and the
foreman puts two vertical guides to keep the legs (cables linking the net to
the otter doors) open.
In the stern there are the gallows, where the otter boards
are stored when we are not fishing . The next step is attaching the otter
boards to the net, which is done with yet more cables called spans.
Then the towing warps are paid out from split winches, their
length depending of depth. The otter boards drop to the bottom, dragging the
net with them. When the warps become tense, the otter boards open with the
water flow, and at the same time the vertical opening of the net decreases.
When the distance between doors is adequate and the net is on the bottom we say
the gear has been set and we start counting the 30 minutes our hauls last.
