Pond Boss Forums STOCKING A NEW POND Types of fish to choose growth rate of BG -v- HBG

Compare apples to apples - all male BG pond vs HBG.

The science says HBG grow faster at first but over time they are about the same size. Aggression and sample size (few caught vs whole pond)make a huge difference. BG learn not to bite but HBG mostly do not due ,in my opinion, to GSF genes/hybrid vigor. Most BG/HBG studies I have seen are real ponds not a lab.
