The girl that took my order says that these bluegill redear hybrids they have found out are 50% males 50% females
For the "found out" opinion, I am convinced that this seller of 'specklebellies' obtained from Malone is lacking direct experience of acturally counting and quantifying the reproductive ability of specklebellies. IMO their opinion was generated from some of their buyers and pond owners of specklebellies. It is doubtful that if the pond owner saw some of what was considered a lot of small hybrids or some type of sunfish the pondowner assumed the worst as 50:50 male - female specklebelly. Even the 'old' regular HBG with high numbers of male/female ratio can have large numbers of offspring result when not adequate predator presssure was applied to the offspring of hybrids. Just one lowly female hybrid sunfish would be capable of having 5,000 to up to 40,000 eggs. That is a lot of offspring production for a regular 0.2 to 1.0 ac pond.
I would like to see the research study, the methods, and test results of the claim that BGXRES hybrids produced 50%male / 50% female F1 offspring when all the scientific research says it does not happen. IMO something is not up to standard operating proceedure with the claim of BGXRES producing equal number of males and females. I trust the experience and research testing done by the hatchery that produces the BGXRES hybrid. They are not novices of fish production. And all the independent scientific testing results also showed a significant high percentage of Males present in the BGXRES cross.
