Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Cormorants?

If I'm about to resail waters you've already charted, excuse and ignore.

Hybrid Bluegill sold commercially are invariably BG crossed with Green Sunfish (GSF). HBG of any variant have greatly reduced fertility wrt regular BG, largely because they are primarliry of just one sex. Almost all species combos, including BGxGSF, are predominantly male - by some studies as high as 97%!

If you read through the many (many, many) threads on HBG here, you will see a lot of spirited discussions on their purported merits and drawbacks. For your goal of managing 3/4 acre "for BG", I think they should prove quite accectable. They primary drawback will be the need to restock more as your original HBG are depleted.

Without getting into a long winded or longhaired discussion (plenty of both are available in existing threads for you to read if interested), the relatively small numbers of offspring that HBG do produce are not as desirable as the original stockers. Personally I don't have much of an idea how Walleye would do to control these "F2+" offspring, or how Walleye do themselves inthis situation, but like many here I am interested in finding out.
