3 PERMA SKIRTS - PREVENTIVE MEASURES Sea lice are, along with escapes, are considered the biggest challenge for the aquaculture industry of today. We see major sea lice infestation on fish residing in the upper water layers. Shielding of the upper portion of a cage may therefore reduce sea lice infestation significantly. Slings in corners give lifting points with high durability for rough treatment Solid, 90mm web around the skirt gives great steadiness and durability The top of the skirt consists of polyester fabric, 495 g/m x60mm float eases the installation. Single float or no float on request. Attach loops in 50mm web every 60 cm allows great flexibility when the skirt is attached to the float ring. Straps with rope every 7.5 m acts as a lift curtain. You can adjust the depth of the skirt according to the current, treatment and oxygen level. Lead cable on the bottom makes the skirt more stable in the sea. Lead cable woven into fabric, gives less wear than a chain. Weight of lead is 2, 4 or 6 kg lead/m. Botngaard delivers skirts with depths from 4.5 down to 10 meters. Frequently used depths in relation to experienced sea lice infestation is 7.6 and 9.6 meters. botngaard as Valsnesveien 259 N-7165 Oksvoll

4 OUR DELOUSING TARPS 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 is 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 are 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.

6 DELOUSING TARPS TECHNICAL SOLUTIONS 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. Double yellow border web; one web running. along the entire perimeter of the fabric and one web going 1 meter into the tarp. Yellow web has a tensile strength of 13.5 tons. Labels on the tarp with numbers and general product information made with specially printed PVC. This gives identification with extreme durability. The slings are anchored in yellow web that runs through the entire tarp. The weight of the tarp is taken up by the reinforcements and not of the fabric itself. Straps for attachment in orange web with a tensile strength of 5.2 tons is affixed to the inner web. This makes Botngaards tarps even more durable. The delousing tarp is further reinforced into the center of the tarp with green web having a tensile strength of 9 tons. PVC over the webs on the inside of the tarp protects the seam against wear from the bottom ring. PVC in 4 colors marks and protects the tarp around the outer edge.
