Given an overabundance of small prey fish, how long does it take for 4-5" SMB to grow 18" long? I only added 10 SMB to a 1 acre pond full of small fish from a stocking of 50 GSH, 25 YP, 25 RES, and 5 lbs of FHM a couple years earlier. I see a great many 1-3" fry in the pond. Also, I was planning to wait until 2018 to start fishing. Is there any reason to start earlier? This spring I caught FHM and small YP and GSH in a minnow trap.
