Hi my brother and his kids have been enjoying my small (1/3rd acre)pond.He is concedering building one himself,but like most of us money is a issue.We would like to know what is the smallest practical size for a trout pond.We have access to feed trained fingerlings near by that range in size from 3-11 inches.Our plan is to stock larger fish and feed and catch though the summer.Holding them over the winter is not a issue because the restocking price around here is decent so his plan is to reload each spring. We are located in southern manitoba canada,he was hoping to get away with a pond roughly 8 feet deep,and as big as he can get it until the bank manager (his wife) says enough.Any thoughts or advice would be great.Thanks in advance.
