The results of this research show that substituting fishmeal with bean flour, in extruded aquaculture feed diets, does not affect (p < 0.05) the final protein content of the diets, whereas you can have cheaper and more shelf stable products.
The best extrusion conditions with a low sinking velocity were determined, which increases feed intake and reduces feed loss at the bottom of the ponds.
Our results show that the best extrusion conditions for aquaculture feed are obtained with extruded diets containing 15% of bean flour processed at 22% moisture content at 120 ºC.
