Thanks for your helpful reply. We understand it is a lot of fish for 3.5 acres, but we didn't know what the mortality rate for the fish would be. We just know that we have to find a solution to the problem and we don't know what the problem is. I feel there is habitat issues with the pond. With issues i mean that there is not enough habitat that the bass feels they can spawn in, and not enough habitat for the fingerlings can survive. I would really like to know about hydrilla, if you can plant it and control it enough. If there is such a thing. We have another pond that is maybe 3 feet deep with a lot of grass and the fishing is unbelievable. Any reply would be greatly appreciated.
