I'm currently re-stocking an outdoor pond Appr. 1 acre, in size with walleye. I've been catching and re-homing all the bass I can prior to putting the walleye in. Talking with the fish farm, they just told me that the fish will only be about 4 inches by oct., the planned date to put in pond. My question is has anyone tried growing walleye for a few months in large rubber maid containers? was thinking of a 300 gal. with a good pond filter for about 20 or so fish? any thoughts??
