A year or two ago once I learned my old pond had a BH spawn I did a lot of reading about BH's. One particular article by a person that enjoyed BH's said to enjoy them while you can. His message was that in a farm pond that had adequate LMB for predators BH's would eventually go by the wayside.
Whatever BH are big enough the LMB can not eat will either be fished out or die of old age eventually. All the spawn and small BH will be controlled by the LMB.
The article talked like that good BH fishing ponds eventually went the way of being a LMB pond. Take that for what it is worth. It is just what I read.
I can let you know in a few more years how it worked out.
