New member but have read tons of info on the site. Thanks for all the great info. I have a 7 acre sand pit that has been established for 20 yrs. currently we have a lot of small bass with the majority in the 8 to 15in, crappie in the 9 to 16in, gills in the 6 to 11in, channel cat and carp. We are wanting to introduce perch and some walleye. The lake doesnt have a ton of structure but plan on dropping many cedar trees and pvc setups to help. The plan is to put in 5-7in perch and walleye this fall. We plan on doing about 150 walleye and 400 perch this year and then about the same next year and maybe the year after. My question is will the perch survive if they are in that 5-7in range. I realize the walleye wont reproduce which is fine. Our main goal is to keep the nice crappie and gills currently along with growing a nice perch population. The bass are not a priority at this time. Please help with any advice. Thanks again!!
