Eric thank you for writing the article and presenting the information. I have read the article more than once and am still trying to come up with a plan of action to combat this problem. I think this is a problem every pond owner on pond boss has.I can see the first and most obvious solution is to fish less. the other article in this issue "do fish genetics need to be refreshed" has some information that ties in with what you're saying, Eric. Eric what practical ideas do you have for combating this problem?
