<strong>The</strong> Aquagrid ® <strong>Complete</strong><br />

<strong>Containment</strong> <strong>System</strong><br />

Because Farmers Need More Than Just a Great Net.<br />

When fish farmers needed an exceptional netting product,<br />

TenCate not only listened, they responded by pioneering a new<br />

net assembly technology. And since 2004, fish farmers across<br />

the globe have benefited from the strength, durability, and cost<br />

effectiveness of Aquagrid ® nets.<br />

So when the same farmers started talking about the need for<br />

a truly complete aquaculture system, TenCate assembled the<br />

necessary parts and recommended partners to meet their<br />

customer’s needs.<br />

Composed of seven interrelated components, the Aquagrid ®<br />

<strong>Complete</strong> <strong>Containment</strong> <strong>System</strong> gives farmers a total aquaculture<br />

package designed to achieve maximum cage integrity, operational<br />

efficiency, and long-term economic viability.<br />

Aquagrid ® Semi-Rigid PVC Coated Polyester Netting<br />

Up to twice as strong as<br />

traditional nylon nets,<br />

Aquagrid ® netting serves<br />

as the base component in<br />

the Aquagrid ® <strong>Complete</strong><br />

<strong>Containment</strong> <strong>System</strong>.<br />

Besides reducing costs,<br />

cutting escapes, and<br />

improving productivity,<br />

Aquagrid ® netting is also<br />

designed to be cleaned in<br />

situ (where regulations<br />

allow), improving fish<br />

health due to better oxygen<br />

delivery and flushing action.<br />

Aquagrid ® Hot Air Welded Seams<br />

TenCate pioneered a new net<br />

assembly technology – hot air<br />

welding. This unique technique<br />

melts the PVC coating of the net<br />

and bonds it to a woven, PVC<br />

coated webbing that forms the<br />

seam between the Aquagrid ®<br />

panels – delivering seam strengths<br />

4 times greater than hand laced<br />

nylon netting seams.<br />

Because the seam is relatively<br />

flat and smooth, there is less<br />

likelihood of irritation or injury if<br />

fish brush against it; and the low<br />

profile makes it easier to clean.<br />

Custom Cage Construction<br />

INDUSTRIAL FABRICS<br />

Aquaculture<br />

Aquagrid ® <strong>Containment</strong> <strong>System</strong><br />

Available in 3 sizes (12.7mm, 19mm,<br />

and 25.4mm), Aquagrid ® netting can<br />

cut your 10-year operational costs by<br />

70% versus traditional nylon nets.<br />

<strong>The</strong> hot air welded panels<br />

of Aquagrid ® netting are<br />

now certified to the<br />

NS 9415 standard via<br />

Novatech in Chile.<br />

Fully assembled cage construction is available through Novatech, Ltd.,<br />

an experienced partner of TenCate . <strong>The</strong>se Aquagrid ® recommended<br />

cages are customized to allow for specific water depths, currents/<br />

waves, and settings for selected fish species.<br />

Novatech, along with NISA, a Puerto Montt, Chile net loft with<br />

years of experience assembling cages produced with Aquagrid ®<br />

netting, can provide assistance in cage design, and offers<br />

customers the opportunity to purchase a fully assembled cage<br />

that meets strict Norwegian standards, complete with Aquagrid ®<br />

PVC-coated nets.


Lift-UP ® Mortality Retrieval Unit<br />

In-Water Net Cleaning<br />

Eliminating the need for costly divers, this airdriven<br />

retrieval system brings undigested feed,<br />

feces, and mortalities out of the cage. Farmers<br />

can use the Lift-UP ® system daily to maintain a<br />

clean farming environment and reduce the<br />

potential spread of bacteria and viruses.<br />

In addition, this system also improves fish health,<br />

boosts fish growth, and removes the temptation<br />

of dead or dying fish from potential predators.<br />

TenCate recommends the use of<br />

an in-water rotary cleaning unit<br />

to remove microorganisms from<br />

Aquagrid ® netting. Many<br />

commercially-available rotary<br />

cleaners can be used, including<br />

the Novatech Mermaid unit.<br />

<strong>The</strong>se machines are designed to<br />

Rotary Net Washing Machine:<br />

operate from the surface for fast,<br />

Aquagrid<br />

efficient cleaning. Safe for daily<br />

use, these rotary units allow one<br />

or two operators to rapidly clean<br />

the cages from the surface,<br />

significantly reducing labor costs associated with divers.<br />

® nets are not only designed to<br />

stay in the water, they are also intended<br />

to be cleaned in situ (in the water where<br />

area regulations allow).<br />

Easy Harvesting Method<br />

With the TenCate recommended harvest flotation system, fish are allowed<br />

to naturally begin crowding towards the top – making it easier to scoop or<br />

peculator them out.<br />

Using a harvest flotation ring, there is no need to remove the net or<br />

disengage mooring systems. This system allows farmers to harvest their<br />

fish crop with low labor and equipment costs. And since the net can be<br />

raised at various paces, you get maximum retention of even the most<br />

finicky species. (See diagrams at right.)<br />

Geotube ® Dewatering for Waste Removal<br />

Waste removal is a large problem in the aquaculture industry. Geotube ®<br />

dewatering technology has applications for fish processing, cage bottom<br />

clean-up, and net washing.<br />

Used in conjunction with the Lift-UP ® mortality retrieval unit, undigested feed<br />

and feces are delivered to the surface where they are collected in batch,<br />

mixed with polymers, and then pumped to Geotube ® dewatering units.<br />

This waste collection feature captures 95% of all solids and retains valuable<br />

nutrients that can be used as a fertilizer or other nutrient source.<br />
