THE GOOD CONCEPT

The GOOD concept provides optimal conditions for cleaner fish. It is important to

acknowledge the cleaner fish’s biology and behavioral patterns to protect it from

danger and give it the opportunity to return to safe grazing areas. Correct

protection, adapted feeding and a clean environment provides the cleaner fish with

the best prerequisites for effective lice grazing. The GOOD concept is a collaboration

of four different products from OK Marine consisting of the cleanGOOD, feedGOOD,

liveGOOD and leadGOOD. cleanGOOD is the main hide which provides the cleaner

fish with the best possible environment and is an effective meeting place for the

salmon and the cleaner fish. feedGOOD is a reliable and robust cleaner fish feeder

designed to provide a minimum of maintenance at all conditions. leadGOOD will

lead the cleaner fish from the bottom of the pen and back for the survival of wrasse in

winter, as the wrasse swims deeper at colder temperatures. Without a hiding place at

the bottom of the pen, the wrasse does not have anywhere it can hide and hibernate.

liveGOOD provides the lumpfish with a safe resting place when it is led to the net by

currents, thus increasing the survival of cleaner fish in exposed conditions. The

concept is designed to take care of all the cleaner fish’s needs and to reduce

mortality. Every component works together and compliments each other to make the

cleaner fish as efficient as possible. The GOOD concept has been developed in

close collaboration with breeders and is based on solid competence and long

experience. It is easy to clean or replace the equipment.

Several fish farmers have experienced that during the crowding of fish the sealice

separates from the fish and moves freely in the water. This causes an infection risk

for the farm, farms close by and for wild fish. CatchLICE is a harvesting net designed to keep the lice inside the net

It is easy to use and is gentle on the salmon. The sealice are bigger

than the openings of the mesh, and prevents lice from re-spreading by pumping lice

on board the treatment vessels to gather in the filters.
