BARGO, High velocity towing of live fish |
|
|
|
|
The Bargo is constructed such that the water
current inside the bag can vary independent of
how fast it is towed through the sea. The water
speed flowing through the bag is regulated, and
the water current can thus be adapted to the
swimming speed that is suitable for different
species. The fish can swim slowly and calmly
while being transported towards its destination.
When the bag reaches a certain speed, it is
pushed down just below the surface where the
water resistance is less. Like a submarine, it will
run far better submerged than in surface
position because it requires less engine power
and saves energy.
“One of the advantages of
the bag is that live fish can be transported much
faster than today. For example, a tow of saithe
that takes 30 hours with a regular seine bag
takes only six hours with the new towing bag”,
says Senior Scientist Kjell Midling at
Fiskeriforskning. Together with Scientist Kåre
Aas, he has played a key role in practical
testing and adaptation of the bag since the
beginning of the project six years ago.

Bargo
- The bag is towed at speeds up to 7 knots
(compared to today, where the speed for towing
live fish is around 1.5 knots).
- The bag is made in different sizes, according
to need. The largest holds 100 tonnes of fish.
- The wall in the bag is made of the same
material used in airbags in cars.
The bag is patent protected in all major fishing
countries.
- Won first prize in the Venture Cup in 2001, a
national competition for new business ideas.
- The bag is developed in collaboration with
Fiskeriforskning.
