Spotted Bass Identification
Spotted Bass
Micropterus punctulatus
Other names: Kentucky spotted bass, spotted black bass Status: Texas
game fish
Description
Micropterus is Greek meaning "small fin" [see Guadalupe
bass for further explanation]. 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.
Angling Importance
Despite the fact that spotted bass are not nearly so large and numerous as
largemouth bass (in Texas their maximum size is less than one-third that of
largemouth bass), they are excellent fighters. Spotted bass are very popular in
east Texas, particularly in the Sabine, Neches, and Cypress Rivers. Known
maximum size in Texas exceeds 5.5 pounds.
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.
Distribution
Spotted bass are distributed throughout the Ohio River basin as well as the
central and lower Mississippi River basin. The species may be found in Gulf
Coast states from Texas east to Florida. Spotted bass are native to portions of
East Texas from the Guadalupe River to the Red River, exclusive of the Edwards
Plateau region.
