Black Soldier Fly Larvae Meal vs. Soy Protein Concentrate Meal: A Comparative Digestibility Study in Barramundi (Lates calcarifer)

Table 4

Mean values (n = 3) of survival, feed intake, growth, and feed conversion in juvenile barramundi receiving control, black soldier fly (BSF), and soy protein concentrate (SPC) diets compared with those receiving commercial feed (Com)¹.
