Omega-3 fatty acids, which are essential nutrients for good health, play a vital role in the immune system and contribute to normal heart function and brain development. It is impossible for the human body to make omega-3, so it is vital to consume these essential fats.
Although fish and seafood are the only sources of omega-3 in human diets, more than half of all fish is now farmed. The only way to guarantee high levels of omega-3 was to use fishmeal and oil, which are marine ingredients.

The rapid expansion in fish farming over the past two decades has been made possible by increasing the dilution and substitution of traditional marine ingredients with cheaper alternatives, mainly plant meals and vegetable oil that lack omega-3 fatty acids. These alternative feeds for Atlantic salmon farming have seen the omega-3 levels in farmed salmon drop by half in recent years.
Fish health is just as important for humans as it is for fish. Alternative, lower-quality marine feeds have been developed to address a variety of issues, including a higher incidence and severity for inflammatory diseases and poor performance in farmed fish. Inflammation is also a critical component of the immune system to all pathogens. Therefore, the current low levels in omega-3 for farmed fish feeds have adverse effects on fish welfare and health.
