We produce fish farming cages in all sizes and designs, and adjust the solutions to accord with your wishes and our recommendations. All of our fish farming cages are certified with respect to NS9415, and our analysts perform class 0 analyses when this is required.
We always design fish farming cages in accordance with your desires, and combine them with our own experiences and specific requirements for the system. During the design process we evaluate and analyse how exposed the location is with respect to its weather and waves, and precisely what type of ring the cage should sit in. We adapt the cages for the ideal perimeter and depth, as well as the type and size of the fish that will be in the cage. In this regard we also assess what the correct choice of materials will be for those who will be managing the cages while in operation. At present two types of cages are primarily used in aquaculture: circular cages and conical cages, but we also supply rectangular cages and spagetti cages. For each of these types of cages, there are a large number of variations and special designs, and we are committed to finding the correct design and choice of materials for you.
We offer circular, spaghetti, conical and rectangular cages in materials such as nylon, HDPE, Dyneema® and Plateena Neo. All our cages are certified pursuant to NS9415.
Our circular, spaghetti, conical and rectangular cages can be produced with the following nettings:
Nylon is a knot-free netting that can be delivered in the colours white and black. The netting is boiled before its production is completed in order to limit shrinkage effects.
Plateena Neo is a knot-free UHMWPE netting that in relation to nylon features an extremely high breaking strength with an eye to the strand thickness. This has a positive result on both the weight of the cage and the solidity in the netting. Plateena Neo netting can be impregnated and can be delivered in white and black.
Sapphire Excel is an HDPE netting with knots that is extremely well-suited for localities with predator challenges. This netting has a limited shrinkage effect in relation to nylon. It is blue and cannot be impregnated.
Sapphire Excel Plus V2 is an HDPE netting with knots and has a steel core that makes it well-suited for localities that have predator challenges. This netting contains copper for an antifouling effect and makes it well-suited for washing. The shrinkage effect in Sapphire Excel Plus V2 is limited in relation to nylon.
Star is a knot-free HDPE netting that is well-suited to washing and which has a limited shrinkage effect in relation to nylon. Star netting is light blue in colour and requires a higher strand thickness than nylon, Plateena Neo and HDPE line with knots in order to attain an equivalent breaking strength.
Star V2 is a knot-free HDPE netting that contains copper for an antifouling effect, and which is well-suited for washing. Star V2 netting has a limited shrinkage effect in relation to nylon, but requires a higher strand thickness than nylon, Plateena Neo and HDPE line with knots in order to attain an equivalent breaking strength. Star V2 netting has a brown colour.
In addition to these selected materials, Selstad is also able to offer netting in other materials – such as HDPE netting with knots outside the steel core.
All our fish farming cages are produced by our partner. Garware Technical Fibres Ltd., in India, before completion and final inspection are carried our at our service stations in Norway.
The cages are delivered complete with user handbooks and packed in accordance with the customer’s needs in order to ensure effective and safe setting out.
At Selstad we place a strong emphasis on innovative solutions with the designs and materials for our fish farming cages. Since our entry into Norwegian aquaculture in the middle of the 1980s, we have had a strong emphasis on product development through the use of new materials and designs in order to ensure high-quality functional solutions.
