Hello. Have a 7 acre old sand pit in nebraska and looking to introduce perch. Max depth of about 24ft. Currently over populated with bass which is resulting in big gills and crappie. Also have catfish and carp in the lake. Looking at introducing perch and if i do will be 7-8in perch. Will stock them right before ice up to help elimate the bass predation. Very few bass over 15in from what i have seen or caught. Any advice as far as how many to stock per acre? Thanks!
