Biology:
Spotted bass seem to be segregated by habitat type from closely related species. They tend to be found in areas with more current than largemouth bass, and they usually inhabit areas that are too warm, turbid, and sluggish for smallmouth bass. Although a large proportion reach maturity within a year, spotted bass found in spawning areas are usually three to four years old. Rock and gravel are usually chosen as suitable spawning areas at water temperatures of 57-74°F. Nest depths may vary widely. Females may lay between 1,150 and 47,000 eggs. Males guard the eggs during incubation and for up to four weeks after they have hatched. As young fish grow their diet shifts from zooplankton to insects, and finally to fish and crayfish.
