I have a 5 acre 37'deep pond (oval shaped, shallow at both ends, steep shoreline at sides)that I stocked with 75-2" to 4" LMB a few years ago. They survived through that winter and were 10" by the next July. Put in 50 more but never saw them again.(winter kill?).Close to sustaining LMB? Would a windmill aeration system help? If so, how deep should the diffuser go? My property has no electricity and is in the Bancroft area of Ontario, Canada. Lots of ice and snow. Any suggestions welcome.
