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.
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.
