what sort of scale is best for small sized fish? I'd love to get one and hand on officially weight/measure them. I also hand feed Optimal daily....mid March'ish - October. I've never known how much to feed, and just feed 2 16oz cups daily each morning. When driving up on the dam, it looks like a 30mph wind just kicked up with all the ripples and waves headed to the dock. within seconds all the food is gone.
with regard to 8" fish, they all look similar....and these are the HBG that i stocked in AUgust 2019 that were 2-3".

.20 acre pond-that leaks/4-5' deep. Stocked 6/22/19 with 300 BG(supposed to be HBG, removed 100+/- so far), 100 RES, 3carp. On 8/20 added 300 HBG, + 21 5"HSB. 8/21 added 5 8" SMB, one 10" LMB , one 14" CC
