Insights on Feed Characteristics of Tuna Moist Extruded Aquafeeds Using Glycerol

Extruded aquafeeds have been used to replace natural food supplies. As tuna aquaculture still relies on fish stocks, the development of formulated extruded diets is essential to guarantee its responsible intensification. Accordingly, three extrusion trials were done aiming to optimize the extrusion process in extruded tuna diets, namely, a pre-trial with varying levels of dietary lipid (6, 8, or 10%), trial 1 with varying die temperature (40, 80...
