The Aquagrid® Complete Containment System - Maccaferri New ...

The Aquagrid ® Complete
Containment System
Because Farmers Need More Than Just a Great Net.
When fish farmers needed an exceptional netting product,
TenCate not only listened, they responded by pioneering a new
net assembly technology. And since 2004, fish farmers across
the globe have benefited from the strength, durability, and cost
effectiveness of Aquagrid ® nets.
So when the same farmers started talking about the need for
a truly complete aquaculture system, TenCate assembled the
necessary parts and recommended partners to meet their
customer’s needs.
Composed of seven interrelated components, the Aquagrid ®
Complete Containment System gives farmers a total aquaculture
package designed to achieve maximum cage integrity, operational
efficiency, and long-term economic viability.

Aquagrid ® Semi-Rigid PVC Coated Polyester Netting
Up to twice as strong as
traditional nylon nets,
Aquagrid ® netting serves
as the base component in
the Aquagrid ® Complete
Containment System.
Besides reducing costs,
cutting escapes, and
improving productivity,
Aquagrid ® netting is also
designed to be cleaned in
situ (where regulations
allow), improving fish
health due to better oxygen
delivery and flushing action.
Aquagrid ® Hot Air Welded Seams
TenCate pioneered a new net
assembly technology – hot air
welding. This unique technique
melts the PVC coating of the net
and bonds it to a woven, PVC
coated webbing that forms the
seam between the Aquagrid ®
panels – delivering seam strengths
4 times greater than hand laced
nylon netting seams.
Because the seam is relatively
flat and smooth, there is less
likelihood of irritation or injury if
fish brush against it; and the low
profile makes it easier to clean.
Custom Cage Construction

Aquaculture
Aquagrid ® Containment System
Available in 3 sizes (12.7mm, 19mm,
and 25.4mm), Aquagrid ® netting can
cut your 10-year operational costs by
70% versus traditional nylon nets.
The hot air welded panels
of Aquagrid ® netting are
now certified to the
NS 9415 standard via
Novatech in Chile.
Fully assembled cage construction is available through Novatech, Ltd.,
an experienced partner of TenCate . These Aquagrid ® recommended
cages are customized to allow for specific water depths, currents/
waves, and settings for selected fish species.
Novatech, along with NISA, a Puerto Montt, Chile net loft with
years of experience assembling cages produced with Aquagrid ®
netting, can provide assistance in cage design, and offers
customers the opportunity to purchase a fully assembled cage
that meets strict Norwegian standards, complete with Aquagrid ®
PVC-coated nets.

Lift-UP ® Mortality Retrieval Unit
In-Water Net Cleaning
Eliminating the need for costly divers, this airdriven
retrieval system brings undigested feed,
feces, and mortalities out of the cage. Farmers
can use the Lift-UP ® system daily to maintain a
clean farming environment and reduce the
potential spread of bacteria and viruses.
In addition, this system also improves fish health,
boosts fish growth, and removes the temptation
of dead or dying fish from potential predators.
TenCate recommends the use of
an in-water rotary cleaning unit
to remove microorganisms from
Aquagrid ® netting. Many
commercially-available rotary
cleaners can be used, including
the Novatech Mermaid unit.
These machines are designed to
Rotary Net Washing Machine:
operate from the surface for fast,
Aquagrid
efficient cleaning. Safe for daily
use, these rotary units allow one
or two operators to rapidly clean
the cages from the surface,
significantly reducing labor costs associated with divers.
® nets are not only designed to
stay in the water, they are also intended
to be cleaned in situ (in the water where
area regulations allow).
Easy Harvesting Method
With the TenCate recommended harvest flotation system, fish are allowed
to naturally begin crowding towards the top – making it easier to scoop or
peculator them out.
Using a harvest flotation ring, there is no need to remove the net or
disengage mooring systems. This system allows farmers to harvest their
fish crop with low labor and equipment costs. And since the net can be
raised at various paces, you get maximum retention of even the most
finicky species. (See diagrams at right.)
Geotube ® Dewatering for Waste Removal
Waste removal is a large problem in the aquaculture industry. Geotube ®
dewatering technology has applications for fish processing, cage bottom
clean-up, and net washing.
Used in conjunction with the Lift-UP ® mortality retrieval unit, undigested feed
and feces are delivered to the surface where they are collected in batch,
mixed with polymers, and then pumped to Geotube ® dewatering units.
This waste collection feature captures 95% of all solids and retains valuable
nutrients that can be used as a fertilizer or other nutrient source.
