W J Knox - Fish Health Nets

Non-chemical products for better fish health are being continually developed and improved, in conjunction with GWRL. The robust and porous woven X12 material forms a barrier between the cage collar and net to exclude lice larvae. It can be tubular or overlapping, with monitoring showing better oxygen exchange than with standard polyester. Wrasse hides or even combination hides for all cleaner fish can be strung across the cage and are available in lengths to suit. When chemical treatments are considered, we supply wedge and cone-shaped tarpaulins, and will repair and renovate as required.
