The cyclone is easy maintenance and o and move during :essary operations. AKVA Subsea Feeder is an underwater feeding system that feeds fish at a depth of approximately eight metres. The feed is transported to the cages through a regular air hose. Water is added and passed down through a main pipe. The water is added by using a pump that draws deep water of good hygiene, in order to ensure the required speed of the feed. The feed is then spread using a dispersion unit of 17 meters in circumference with 12 feeding units so that the feed is spread about the cages in a satisfactory manner. The feeding rate is up to 50kg of feed per minute. Experience from using the system shows the need for bird netting is not required. Principal advantages ■ Fast and efficient underwater feeding (50kg/min.) ■ Good feed distribution ■ Good hygiene ■ Easy to operate and maintain ■ No bird netting required AKVAgrour

Promising test results Flotation collar The AKVA Subsea Feeder has been tested by the aquaculture company SinkabergHansen. Experience shows that the fish remain by the feeding point during daytime, resulting in good growth and fish welfare due to reduced sea lice infestation.
