Pond Boss Forums POND CONSTRUCTION Creating habitat The Purpose of Structure

In my new 3/4 acre pond my neighbor and I placed over 50 cement blocks (see photo). We then got into a discussion about the merits of fish habitat. I was of the opinion that it would serve only to concentrate the fish. He thought that it would help produce more and bigger fish. Can someone here clarify the issue? Perhaps structure works to do all three? Is fish habitat the same as structure? By the way, I plan to stock the pond with LMB, BG, and YP (yellow perch). Thanks to any and all who offer their opinion.
