Thank you all, I appreciate your help.
I'll catch n keep some LMB for the general health of all the pond.

In the meanwhile I've just received a pic of a minnow I don't know from that friend of mine who will give me some PS. He has 2 ponds, one with Koi, the other one with CGC, some PS and a bulk of these minnows 3-4" long:


Does anybody know what they are? Could they be good as forage for LMB?
He said they would be easy to catch alot with minnow traps.
