Cod

Pros

Hvalpsund Net - Cage Net for Cod - Although the quantity of farmed cod is significantly smaller than that of Salmon – farmed cod is still an important contribution to the supply of high quality white fish

Although the quantity of farmed cod is significantly smaller than that of Salmon – farmed cod is still an important contribution to the supply of high quality white fish.

 

Once seen upon as the “next big species” – but now more viewed as a niche.

 

Cod are known to bite and chew on net, twine or rope that sticks out in the net pen. If something catches the attention of the cod it will systematically bite and chew on this.

 

The cod can be distracted by putting “toys” into the net pens which will draw the attention instead of the net, rope or twine.

Pros

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

One way to keep the inside of the net pens, made especially for cod, as uniform as possible is to make sure that only dark colored materials are being used.

 

By using only dark colors the net, twine or rope are less likely to catch the attention of the fish.

 

Just as important we make sure that no knots, loose twine or rope ends are sticking out on the inside of the net pens.

 

Also the use of correct materials with sufficient strength and wear resistance is crucial.

 

Finally covering the fully assembled net pen in a dark resin that glues all fibres and filaments together is recommended. Covering the net pen with a resin makes it more difficult for the cod to bite and chew on the materials.

Dyneema®

Pros

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

Why does Dyneema® make an excellent cage net for cod farming?

 

The Dyneema® firbers special properties when it comes to superior abrasion resistance, light weight and ultra-high strength makes it the perfect match.

 

Cod farms are seeing significant reductions in holes and damages to the net, twine and rope related to fish bites after switching to Dyneema®.

 

The thin twine results in less fouling that closes meshes as well as it takes longer for the fouling to attach. That in turn ensures higher water flow and better oxygen levels which increases fish welfare and a leads to better FCR.

 

Reduced service and logistic costs are elements that contributes to the fact that Dyneema® is an excellent choice for cod farmers.
