Our Feed is made through a process called extrusion. Extrusion is a method of cooking both human and animal foods and is ideal for fish feed production. Extrusion involves cooking the raw ingredients at high temperature, moisture and high pressure for a short period of time, before pushing the mix through a die to form a pellet. A diagram showing the stages of extrusion can be seen in accompanying image.

The advantages of extrusion include enhancing the digestibility of starch whilst preserving the digestibility of proteins, providing a honeycomb structure to carry the fat (energy) content of the feed. This makes the feed very concentrated and decreases waste as less pellets are needed for each fish to get the nutrition they require. The biggest advantage, however, is the ability to control the buoyancy of the feed and how it behaves in the water. Certain fish, such as barramundi, require their feed to float, while others like salmon, prefer their feed to sink. Extrusion allows us to not only control whether our feed float or sinks, but also the rate it sinks at. All in a pellet with good water stability. This helps the fish to eat as they want and underpins efficient growth.
