† Populations may not be currently present.

* HUCs are not listed for states where the observation(s) cannot be approximated to a HUC (e.g. state centroids or Canadian provinces).


Means of Introduction: Populations maintained through stocking programs. Alabama has stocked more than 18 million palmetto bass since 1974 (Mettee et al. 1996).

Status: Populations maintained through stocking programs.

Impact of Introduction: In the Savannah River, backcrossing to striped bass was observed (Avise and Van den Arvyle 1984). These hybrids also occasionally back cross with white bass (Avise and Van den Arvyle 1984; Etnier and Starnes 1993). The potential outcome of such mating includes loss of genetic integrity of the parent species or even the loss of a native species, subspecies, or of a unique population (Campton 1987). Sunshine bass apparently are backcrossing to parentals in the Ohio River, where this hybrid is very common (Burr, personal communication).

Remarks: The whiterock (palmetto, wiper, Cherokee) is the result of crossing a female striped bass with a male white bass, and was first cultured in 1965. The sunshine bass, first produced in 1973, is the result of the reverse cross (Ware 1975; Kerby 1979; International Game Fish Association 1994). Most introductions are of the whiterock hybrid; however, a few sites have been stocked with sunshine bass, including some lakes in Florida (Ware 1975). These hybrids reportedly grow faster, survive better, and are caught more readily than striped bass (Ware 1975). However, they don't attain as large a size as do striped bass (Gilbert, personal communication). These hybrids occur naturally in Arkansas (Etnier and Starnes 1993).

Law enforcement officers and fishermen have significant trouble distigushing the hybrid from the Striped and White basses.  In an effort to solve this problem, Williams (1976) measured numerous specimens from South Carolina reservoirs and determined helpful distinguishing characteristics.  He found that the number of patches of teeth on the tongue, ratio of fork length to body depth, and the ratio of body depth to head length can be used to distinguish the 3 species.  The previous use of the "broken line syndrome" is not a reliable method of identification.
