Via Bill Cody research - BG reproduction potential
Here is some reference information about bluegill spawning and potential of producing fry. In BG behavior a territorial male sometimes spawns with more than one female in succession. Eggs in the nest could represent a maximum effort of one female or if the egg total was from several females as this is still unclear. One 6 inch female BG in Mississippi contained 12,000 eggs. Female BG from a study in Minnesota contained 15,000 to 58,000 eggs. Another study showed the average BG nest contained 15,000 eggs. An Indiana study of BG nesting colonies showed the counted eggs in each of four nests to have 11.2K, 30,3K, 80K and 224,000eggs!. The higher egg counts in nests of this study unlikely came from one female. Are you sure you want mixed sex BG in this tiny pond? LMB with males and females will have the same reproductive potential. Small fish numbers could become crowded quickly and often more commonly in a tiny pond.
