Taking care of your fish
FLS Caligus is a high-performance delouser, focussed on fish welfare
We care about fish welfare because it is both good for the fish and economically important for the farmers. FLS has specialised in delousing for more than 10 years and has gained considerable experience in this ma�er. Salmon is a fragile bundle of muscle, and therefore our focus on innova�on has always been based on the fish’s welfare.
The FLS Caligus delouser is a mechanical delouser that flushes with seawater at seawater temperatures. It is organised as a siphon that pulls the fish from the cage and delivers it back to the cage at the same level. In the vacuumed pipeline this gives low li�ing height which is one of many important benefits by using FLS Caligus.
Pumping pressure affects the fish nega�vely, therefore we aim to perform the opera�on with the lowest possible pump pressure. By using our gentle ejector to move the water and fish through the system, with zero li�ing height, we need a pumping pressure of only 0.35 – 0.45 bar to get the perfect water speed of 2-2.5 metres pr second.
The fish is flushed twice through our gentle full water flushers, which is effec�ve and gentle in delousing, and means the fish can be handled without wounds and injuries. This is achieved in a combina�on of the size of the flushers, pipelines and the precisely flushing nozzles. FLS Caligus flushes with low pressure of only 0.55-0.85 bar, and s�ll removes about 95% of the sea lice.
To ensure an objec�ve assessment of FLS product documenta�on, we engaged veterinarian ins�tutes and other organisa�ons to document the fish welfare and product efficiency.
Successful delousing is a combina�on of capacity (tons per hour), efficiency (delouse percentage) and fish welfare (minimising stress, injuries, wounds, and mortality). With FLS Caligus we have found the right combina�on to delouse the fish without harm.
ur customer Sm la iking, has a FLS Caligus delouser with four lines with a capacity of 200 tones per hour. They can demonstrate mortality rate as low as 0.1% and a delousing effect of more than 95%.
FLS Caligus delousing is a sustainable system
– it treats the fish carefully and has low energy consump�on, and there are no chemicals or hot water involved.
