Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations ID Help; HBG or Pure Strain?

DIED I added your pics back to the original thread. Thanks for reposting.

I agree that fish has a high % of GSF genes.

Pure GSF are not easy to find according to a number of authors and researchers on hybrid lepomis. That is one reason they give for the high variability of the % of male offspring in F1 HBG (BG x GSF) . From 65% male in one study to 98% in another. Some think that the inability to find pure GSF even for studies which are controlled is a major factor. This also may play a part in why HBG have such a wide variety of appearances as per the linked thread.
