Beat egg yolk with egg substitute in medium bowl until thick. Add flour, salt, dill, pepper, and parsley, and stir to blend. Stir salmon pieces into flour mixture.
Beat egg whites until stiff. Fold them into salmon mixture.
Coat a nonstick frying pan generously with canola cooking spray. Start heating the pan over medium heat. Use a 1/4-cup measure to scoop out 1/4 cup of the fritter batter and add to pan. Repeat with remaining batter until pan is full. Continue to cook until bottom side is nicely browned (about 3 to 5 minutes). Turn to other side and cook until browned (3 minutes more).
Remove fritters from pan and repeat step 3 to finish the fritter batter.
