Fish Farm Cages

Hvalpsund Net built the first HDPE cages in the early 80’s. Since then we have had a continuous focus on developing our EXTREME cages into what they are today. Hvalpsund Net has throughout the years built fish farm cages in most parts of Europe, Middle East, Africa, South America, South East Asia and New Zealand.

 

Our cages are available in sizes from 30 to 300 mtr in any 2 or 3 pipe configuration in sizes from 180 to 560mm. We have also supplied square cages used for harvesting or as nursery cages. Here you will find our different options for brackets / stanchions, pipes and options for added features and accessories for fish farm cages

Hvalpsund Net - Fish farm cages - Cages with steel brackets

Cages with steel brackets

We produce steel brackets as both fully welded or disassembled. The brackets are from high quality steel and hop dip galvanized. The advantage of steel brackets is high strength and low cost. Further to that they can be made with any design in small series. The steel brackets are especially suitable for fresh water – or other environments with low corrosion.

Square cages

 

Square cages have some advantages compared to the normal round cages. Often used in more sheltered sites for purposes as “nursery cages” or “smolt cages” but can also be used as harvest cages.

Square cage systems can be built with a centralized walk way of variable width. Full walkway around every cage is also an option. Other features such as integrated bird net poles, and winches for dividing the cage nets can be added.

Specs

The square cage systems can be either as individual cages or built together in larger systems of 4, 6, 8 or even 12 cages – in typical sizes of between 6 x 6 to 12 x 12 mtr. Harvest cages are often constructed in a larger size i.e. 15 x 40 mtr.

Special cage details

 

As no two farmers has the same requirements the cages can be modified in a number of ways to suit exactly the needs of the farmer. The Hvalpsund EXTREME cages also come with a number of special features.

Injection moulded walk way

The injection moulded walk way panels are fitted with anti slip dots and toe stoppers – to meet health and safety requirements.

Bird net pole

An extension of the hand rail upright allows for suspending a bird net without placing any bird net supporter inside the cage. This is especially useful for cages containing delicate fish that does not like objects placed inside the cages.

Predator net pole

When using nets for predators like seals it is an option to hang the net in a way that prevents the seal from jumping up on to the cages. By attaching predator net pole you can hang the net several meters above the water. The pole is made of all HDPE100.

Stainless steel net hook

AISI316 grade stainless steel hook available in various specs and sizes.
