Importance of fish welfare

Safe and gentle sealice treatment

Sea Farm Innovations have developed a new system, to make sealice treatment safer, faster and better. SFI SYSTEM is a new innovative patented system, that has been developed by Sea Farm Innovation, in close cooperation with salmon farmers. The main focus for the SFI SYSTEM has from start been fish welfare, to make sure that as few salmon perish during sealice treatment as possible.

This patented innovative system is the first on the market, where treatment is in full control. There is no harmfull chemical or heat treatment.

SFI SYSTEM is inspired by the salmons natrual behaviour, which minimizes any unwanted side effectes from the treatment.

The SFI SYSTEM has the benefit, that it can be used in connection with most kinds of fish pumps. Therefore the system can be used with the newest and most gentle pump techonologies on the market.

The mortality caused by the treatment is very low while the capacity of the system is up to 200 tonns per hour for a double system.

SFI SYSTEM is very energy efficient and the system itself only uses 150 kWh when running at 100%, while during normal operation the power usage is lower.

Short treatment time

The treatment time itself of the fish in SFI SYSTEM is less than 0,2 seconds. Keeping the treatment time as low as possible has been key, to ensure gentle treatment and minimal stress and mortality.

Less stress ensures that the fish eats normally faster and the starvation period prior to treatment can also be very short.


The SFI System has been developed over the course five years. Tests have been made during all phases of the delvelopment, to make sure that the system is efficiant, has high capacity and has as little inpact on the fish as possible.

The goal was to make a treatment, that did not affect the natural environment. Therefore chemical, thermal and freshwater treatments were out of the question straight from the beginning.

Because SFI SYSTEM does not use tempered water, which makes the system much more Green compared to heat treatment.
