I have started to back off a little. I'm trying to make a 50# bag last me 1 month in my 3/4 acre pond. We hand feed our fish over a 40' area twice a day. We have a boat load of fish that come up to eat. How many is a boat load? Well...best as we can tell, they are thick enough to walk over if you huddled them in a 12' diameters circle. That's why we space ourselves out over 40' when we feed. I'm trying to ensures that all of them can get a little bit. I really don't have any set goals other than a recreation enjoyment. I figure long about Sept, I'm gonna harvest all the big ones I can catch in Catfish and Tilapia. Oh and all the GSF I can catch. The purpose will be so I can add about 30lbs of trout in December, so I can fish all winter.
