The species epithet punctulatus, Latin for dotted , refers to rows of dark spots on the lower sides. Coloration is similar to that of Guadalupe bass, but does not extend as low on the body. Biology Spotted bass have been considered intermediate between largemouth and smallmouth bass. They seem to be segregated from largemouth and smallmouth bass by habitat type.
Spotted bass tend to be found in areas with more current than largemouth bass.
However, they usually inhabit areas that are too warm, turbid, and sluggish for smallmouth bass. In general, although a large proportion reach maturity within a year, spotted bass found in spawning areas are usually three to four years old. Rock or 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.
