Have a 1/4 acre pond 15 foot deep been here for 30 years haven't had fish in for years 2 years ago I stocked 40 3 inch channel cats some died 10 Large mouth bass fingerlings I stocked 25 red ear 3 inch and 25 bluegil 3to5 inchs I fished last year never kept any nice fat bass n sun fish was growing good all the fish had successfully spawn as I have a pond full of fingerling and smaller fish. This being the 3rd year can start keeping correct? I really just want a good pond of keeper size gills and bass n cats that I can eat off throughout the year so how do I no what and how many of each to keep and what to throw back? I don't feed any fish the pond is aerated by wind mill
