What fish eat is of great importance for fish health. Feeds containing krill give many benefits and solve challenges faced in aquaculture. Feeds with krill have optimal fatty acid balance, which results in a strong immune system. A strong immune system is the basis for good health and reduced mortality.
To a large extent, the difference between good health and disease is about the ratio between the number of cells which work well, and those that do not. When working well, they should be able to perform their tasks well, such as fight, transport and communicate with the surrounding cells. The right balance between omega-3 and omega-6 fatty acids is essential to allow cell to work at their optimal level.
Omega-3s contribute to the cell having a flexible and permeable membrane helping to give the right signals.
For optimal health and the capacity to resist disease, fish need a responsive immune system. Inflammation is the body's way of saying that something is wrong and that the immune system should start to fight, for example, a virus or infection.
Omega-6 fatty acids activate the immune system
Omega-6 fatty acids are important for fish to activate their immune system. When the immune system has done its job, omega-3 fatty acids are needed to reduce inflammation.
In order to strengthen the immune system, the balance between the two fatty acid forms is decisive. Too much omega-6s can lead to more inflammation, whereas omega-3s have anti-inflammatory effects.
It is important that fish have access to both, but in order to manage inflammation and infection efficiently, they require the right balance between omega-6 and omega-3.
Studies have shown that by eating krill, fish develop stronger heart muscles and healthier circulatory systems. This results in lower mortality and less disease, as well as improved fillet quality.
