Tuna

Pros

Hvalpsund Net - Cage Net for Tuna - Tuna is in every aspect like no other farmed fish. The wild caught Tuna are gently towed from the fishing ground to the holding pens

Tuna is in every aspect like no other farmed fish. The wild caught Tuna are gently towed from the fishing ground to the holding pens.

 

After having been carefully transferred into the tuna pens the huge and incredibly beautiful fish are nursed for like no other species.

 

Not only are the tuna a lot bigger than other farmed fish species – they are also very delicate and so need to be handled gently. Even small cuts or bruises can ultimately cause that the fish will not survive.

 

Weighing everything from 50 to 800 kg – even losing just “a few fish” is not an option.

 

The tuna fish’ behavior inside the cage is circling inside the net often following exactly the same path.

Pros

Hvalpsund Net - Cage nets - Farming fish in tropical conditions means a lot fouling is growing on the pens all year round

Tuna fish are being kept in pens with a size a lot bigger than many other species.

 

A typical pen size between 150 and 300 mtr circumference combined with the fact that tuna pens often are located in exposed offshore sites demands the ultimate.

 

The side walls of a tuna net must be kept straight not to catch onto the fins of the fish. With the size and weight of a tuna net surpassing e.g. Salmon or Sea Bream nets – special tools and machinery is needed for construction and handling of the nets.

 

Hydraulic pulling tools makes the lashing in critical points stronger that any manual labor can do.

Dyneema®

Pro

Hvalpsund Net - Dyneema - You also reduce the amount of net coatings such as antifouling liquid needed to coat the net. That alone can pay for the slight increase in cost of using Dyneema® over traditional materials as nylon and polyester

Towing of tuna pens are often done over great distances. For days the huge tuna pens are slowly being towed from the fish ground to the holding pens.

 

Towing nets made from Dyneema® drastically reduces the drag forces coming from the net. The reduced drag forces lowers the fuel consumption and reduces cost of towing.

 

Further to that the lower drag forces in the net helps keep the residual volume in the net and the fish are less likely to get caught on the net panels.
