  • 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.
