Answer
Chris; I really shouldn't try to answer this question at all because I am not a fish biologist or anything near it.  My experience has been in fishing not in maintaining fish habitat.  About all I could tell you is that some moss or other weed is not too thick it is good for the fish but if it becomes too thick It may shut down sunlight penetration and reduce the amount of oxygen produced by the plants below and reduce the oxygen supply.  Some types of moss die off and sink to the bottom and decay.  Decay uses oxygen and further depletes the 02 supply.

My suggestion is to check with your state Fish and game authorities and ask them if they have a biologist who can help you.

If the pond once had many fish and now it doesn't there is something definitely wrong with the balance in the pond and it needs someone with knowledge of this kind of thing to tell you what you might do to improve the pond.  

I am sorry I could not give you a more definite answer.  Go to Ohio fish and game on your computer and see what it says about situations like this.  Thanks for calling on me to try to answer your question.  

I am
