Female Gam in pic 4..Bill has them in every pond he owns so good chance it came from there.
My recommendation was to wait on craws until some vegetation is established, after looking at the pond, it's in need of some aquatic veggies. Now that the craws are there we need to play hard-ball and start with some good sized bass
The LMB and HSB I have started to feed train and will be fairly advanced when stocked in the mid to late sept range.
The TGC that were stocked was extreme but we'll deal with it as we go!
