Mission 2011 does not support replacing the protein and nutritional value gained from fish with other animal meats, especially cattle: the cattle industry is a large contributor to global warming from the clear-cutting of forests to methane production (Marian, 2007). We do endorse obtaining the necessary amino acids from combinations of grain/wheat/flour with legumes/vegetables/beans. Additional information on food combining to achieve optimal protein intake from non-animal sources can be found on Protein in the Vegan Diet and on this Protein Information Sheet.
