Partial Replacement of Fish Meal with Soy Protein Concentrate in Diets of Atlantic Cod
In two feeding trials conducted with juvenile Atlantic cod Gadus morhua (initial mean weight = 87.9 or 15.92 g), soy protein concentrate (SPC) was used to replace fish meal in isonitrogenous, isocaloric diets. In the first trial, five experimental diets (47% protein, 15% fat; calculated gross energy...
