Aquagrid®, a specialist semi rigid grid developed to overcome problems identified in finfish farming operations. There are many aspects that can impact operations of cage fish farming systems; predators that can destroy nets allowing fish to escape, strong currents which can reduce the cage volume causing stress on the fish, biofouling which reduces oxygen flow and flushing action, longevity and strength of the net material, as well as market negative issues of using chemicals such as antifoulants and excess nutrients from food and feces.
 
After seven years of R&D, TenCate Geosynthetics North America working with Don Bishop of Bishop Aquatic Technologies in Canada developed Aquagrid®, semi rigid netting designed not only to contain fish, but to address the concerns of the aquaculture industry and the environment. It offers longer life and other benefits over traditional netting used in aquaculture.

Aquagrid®, was designed to exclude predators such as marine mammals and predator fish found in the marine environment’. In salmon culture sea lion attacks causing net damage and fish escapes is a major problem for farming operations. In Chile, farm operations using Aquagrid®, containment systems have reduced escapes caused by predation from an average 12% to less then 1%.

The Aquagrid®, cage system is further supported by new development: Mortality Retrieval System, Aquagrid®,  Harvest Bottom System and the NovaClean specialist in water cleaning system.
