Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants FA, take out by hand or buy some fish?

My pond has FA around 50% of the shoreline and some in the shallow areas of the pond. It is starting to (if it hasn't already) when the war. Should I just rake it out of my 1/2 acre pond or get some fish that eat it? We have mild winters here in the San Joaquin Valley of California. Will the FA die down in the winter? Thanks for any advice.
