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.

Forbesichthys agassizii (Putnam, 1872)

Common name: Spring Cavefish

Synonyms and Other Names: Chologaster agassizi, Forbesella agassizi

Taxonomy: available through www.itis.govITIS logo

Identification: Pflieger (1975); Page and Burr (1991); Etnier and Starnes (1993). Another commonly used name is Chologaster agassizi (Nelson 1984; Robins et al. 1991a). The names Forbesella agassizi and Chologaster papilliferus have also been used in the literature (Weise 1957; Lee et al. 1980 et seq.; Page and Burr 1991). Forbesichthys agassizi is one of two species in this family with functional eyes (Nelson 1984).

Size: 8.4 cm

Native Range: Springs and caves from central and western Kentucky (west to the Tennessee River) to south central Tennessee; west across southern Illinois to southeastern Missouri (Page and Burr 1991).

Means of Introduction: Intentionally stocked from southern Illinois sites to establish a population near Quincy College. This population was intended to serve as a nearby source of fish for research (Weise 1957).

Status: The population apparently failed to reproduce and no longer exists. Weise (1957) suggested that the cavefish were swept downstream and taken by predators.

Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.

Remarks: This species is listed as state endangered in Missouri. There are no known voucher specimens.
