The high demand for fish puts a lot of pressure on the aquaculture industry to increase capacity. Innovations in the field lead to improve efficiency and enabling technologies.

Netmark is a manufacturer of knotted nylon and Dyneema nettings for aquaculture.

The following types of nettings are suitable for aquaculture:

Knotted nylon netting for cages – freshwater

Our nylon nettings are made of high density raw materials with an unique coating which prolong the lifetime and contribute to the higher abrasion resistance and the optimized water flow. These nettings does not require the antifouling treatment.


Dyneema® netting for cages – freshwater and seawater

Nets made with Dyneema® fibers are up to a third of the weight compared to traditional nylon, and have smaller twine diameters.

This results in a reduced drag from current and waves, improving net stability and improving the environment for the fish inside. The well-being of the fish is further improved by the better water flow.

Maintance costs are reduced since the thinner nets need less antifouling chemicals and repairs to the net are reduced considerably.

Nettings made of Dyneema® have a high bite-resistance, which is important in case of farming of cod or sea-bream. This feature extends the lifetime of the nets and reduces the risk of the fish escapes and repairs.


Predator Dyneema®nettings

In some areas the fishfarmers are challenged by predators attacing the nets in order to get a free meal.

Dyneema® nettings has a high knot-strength which combined with a high bite-, cut- and abrasion resistance make Dyneema® fiber the preferred material for the job.


Nettings made of Dyneema® fibers outperform all other nettings.
