The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Aphredoderus sayanus (Gilliams, 1824)

Common name: Pirate Perch

Taxonomy: available through www.itis.govITIS logo

Identification: Smith (1985); Page and Burr (1991); Etnier and Starnes (1993); Jenkins and Burkhead (1994). Two subspecies: Aphredoderus s. sayanus and A. s. gibbosus (Smith 1985; Boltz and Stauffer 1993; Etnier and Starnes 1993).


Size: 14 cm.

Native Range: Atlantic and Gulf Slopes from Long Island, New York, to Colorado river drainage, Texas; Great Lakes and Mississippi River basins from Michigan, Wisconsin, and southern Minnesota to the Gulf. Isolated populations in Lakes Ontario and Erie drainages, New York (Page and Burr 1991). Aphredoderus s. saynus is native to the Atlantic Coast drainages; A. s. gibbosus is native to the Mississippi Valley; and Gulf Coastal populations are considered to be intergrades (Boltz and Stauffer 1993).

† Populations may not be currently present.


Means of Introduction: Unknown; possible bait bucket introduction. Becker (1983) noted that populations are widely separated and stated that it seems probable that the Wisconsin records from the Embarrass River and the upper Wisconsin system, resulted from introductions. He did not suggest a possible means of introduction.

Status: Established in Wisconsin outside what is considered its native range.

Impact of Introduction: Unknown.
