I just got my pond dug for the walleyes. It is a little over 1/2 acre being 20 foot at one end and 10 ft at the other with a 5 foot shelf in between and 5 foot shelf around the edge of the 10 foot side. I have hit a spring and already have close to 7 foot of water in it. Keep in mind this was just finished yesterday-it is filling up with water at an unbelievable rate. My question is since I am putting the walleye in in oct. Do I still have time to put fatheads in or perch to help get the walleyes through until next year?? Or is there some other type of fish that I can put in (knowing that they are walleye food).

Also, How much should I put in-I am putting in 50 walleye.
Thanks!
