NAS - Nonindigenous Aquatic Species |
Common Name: granulated catfish
Identification: Distinguishing characteristics of the genus Pterodoras were given by Higuchi (1992). A few distinguishing characteristics and a key to doradid genera were given by Burgess (1989), although that key should be considered somewhat suspect. The species was also included in illustrations and identification keys of Eigenmann (1925). For photographs of species see Goulding (1980), Sands (1984, incorrectly spelled as Pterydoras granulosus), and Burgess (1989).
Size: 70 cm.
Native Range:
Tropical America. La Plata and Amazon basins of South America.
Nonindigenous Occurrences: A single specimen (55 cm SL) was found dead in a canal north of Brooker Creek, near Lake Tarpon in Pinellas County, Florida, in early 1977 (Courtenay and Hensley 1979a; museum specimen).
Means of Introduction: This fish was probably an aquarium release.
Status: Reported from Florida.
Impact of Introduction: Unknown.
Remarks: The Pinellas County, Florida, record is likely the basis for inclusion
of this species in several published lists of nonestablished,
nonindigenous fishes (e.g., Courtenay and Hensley 1980; Courtenay et
al. 1984, 1986; Courtenay and Stauffer 1990; Courtenay et al. 1991;
Robins et al. 1991b).
Voucher specimens: Florida (FDNR 11967).
