I am going to turn an old catfish pond into a cnbg pond. It is about 50'x50' and 8 ' deep in the middle. All of the catfish are gone and there is a healthy fhm population now. I plan to bucket stock cnbg from my big pond. Can anyone suggest a number of 6-8 inch fish to insure that I get a mix of sexes. I plan to catch the large adult fish and transport them in the next few days.
