thats close to the size of my pond. mine is 20 by 50,and i only have about 4 to 6 gpm during a drout but up to 35 or 40 after a heavy rain. i think with that few trout the size of the pond and the amount of water flow you will easily getaway without aerating. i gues you plan on feeding them since there wouldn't be much forage. good luck update us soon. i'd love to know how your project goes.
