That is very interesting!! Two reasons, first,I had heard the off spring of the HBG was nondesirable several years ago, prior to my owning a pond so hadn't really considered it until I saw all the photo's of these big HBG som of you were posting, it was making my mouth water, so thank you.
Second, when I first started looking at the pond I eventually bought it was absolutly loaded with GSF and stunted LMB, I actually sought the help of IADNR for eradicating the whole pond. I don't know the stocking history so couldn't say but possibly this could have been the case with my pond. Fortunatly the 1999 year was one with an extended snow cover of 12" for most of the winter, this would be the only reason I can come up with in the dissappearance of the entire ponds fish population. Saved me $500 on Rotenone!
Thank you for the discussion and comments, it may have just saved me a headache.
