I would like to see the research to add it to what I have on the subject. I will look and if I find it I will let you know.

Nothing new in that report. I agree in general but you have to read it closely as it contains assumptions and conclusions that could lead one astray.

One point in comparing HBG and BG and the size comment . Keep in mind that with HBG you are measuring near 100% males but with BG half +- are females which has an effect on the size outcome. HBG sellers say HBG grow faster/bigger which is right vs. a BG population but , as noted not right (faster/bigger) than an all male BG comparison. Other data indicate that in general in ponds HBG have an initial faster growth rate but that BG soon catch up.

The experts on this subject note the real hybrid vigor is in their aggressiveness as noted in the report above. HBG have their uses/place in pond mgt. but it is limited. They are not a replacement for BG.

Thanks CB1 for the info.
