Delousing tarp


All Botngaard delousing tarps are tailored to the individual locality. Through surveying our customers' needs, factors as cage size, desired volume, durability and design we can deliver a product that eases the job for fish farmers as much as possible.

Our delousing tarps are made of polyamide fabric with a tensile strength of 3800 N/5cm. The weight of the fabric is 210 gr/m². An important element of a successful bath treatment is the ingress of water. To have control of the amount of medical used the tarp should let through as little water as possible. For a virtually completely sealed delousing tarp Botngaard recommends a tarp produced with a coated polyamide fabric.

Our experience shows that it is very important with right volume when delousing. Botngaard delivers therefore tarps with a design that ensures this. Our experience is that correct equipment for the actual biomass will provide better economic and environmental benefits.


Flat tarp

For delousing all types of cages. Customers have different requirements for design and strength. Botngaard tailors tarps based on individual basis.

The muffin tarp

Designed to reduce the circumference of the tarp, which eases the setting on the cage. Circumference is equal to the cage plus 3 %. Even depth in the tarp gives the least burden for both fish and cage.

Conical tarp 

also known as China Hat. Circumference for a conical tarp is equal to the cage plus 6 %. Suited for cages with conical nets or in cases where you want to limit the volume in the treatment.

Square or rectangular tarps

Made specifically for steel cages. We also produce these tarps shaped as muffin/drawer. It is the size of the cage and desired treatment volume that determines the size of the tarp.
