Introduced in Altamaha River, Georgia; Sisquoc River, California; Puerto Rico; Arkansas; upper Cumberland River drainage, Kentucky, and elsewhere below Fall Line in southeastern U.S. (Lee et al. 1980, Page and Burr 1991). Common, especially in upper Alabama River system (Page and Burr 1991).

Number of Occurrences:  
Number of Occurrences Comments: This species is represented by a large number of subpopulations and locations.

Population Size Comments: Total adult population size is unknown but relatively large.

Overall Threat Impact Comments: Localized threats may exist, but on a range-wide scale no major threats are known.

Short-term Trend Comments: Trend over the past 10 years or three generations is uncertain but likely relatively stable or slowly declining.

Reproduction Comments: Spawns in late spring when temperatures rise to 17-21 C; sexually mature presumably in 2-4 years; spawning behavior similar to smallmouth bass (Moyle 1976).
Habitat Type: Freshwater
Non-Migrant: N
Locally Migrant: N
Long Distance Migrant: N
Riverine Habitat(s): CREEK, High gradient, MEDIUM RIVER, Moderate gradient, Pool
Habitat Comments: Clear upland creeks and small to medium rivers, in rocky runs and pools. Moves up into small tributary streams or the heads of pools in larger streams to spawn (Moyle 1976).
Adult Food Habits: Carnivore, Invertivore, Piscivore
Immature Food Habits: Carnivore, Invertivore, Piscivore
Food Comments: Opportunistic feeder; relies heavily on terrestrial insects. Also consumes aquatic insects, fishes, fish eggs, crayfish, and salamanders (Moyle 1976).

Population/Occurrence Delineation
Help
Group Name: Sunfishes (Centrarchids)

Use Class: Not applicable
Minimum Criteria for an Occurrence: Occurrences are based on evidence of historical presence, or current and likely recurring presence, at a given location. Such evidence minimally includes collection or reliable observation and documentation of one or more individuals (including eggs and larvae) in appropriate habitat.
Separation Barriers: Dam lacking a suitable fishway; high waterfall; upland habitat.
Separation Distance for Unsuitable Habitat: 10 km
Separation Distance for Suitable Habitat: 10 km
Separation Justification: Separation distance is arbitrary. Although members of this group vary in size and probably in typical movement distances, it is likely that even the smallest centrarchids occasionally disperse as far as do large centrarchids. Hence a single separation distance is used for all members of the family. Because of the difficulty in defining suitable versus unsuitable habitat, especially with respect to dispersal, and to simplify the delineation of occurrences, a single separation distance is used regardless of habitat quality.
Date: 25Jun2001
Author: Hammerson, G.
Notes: Note that some species some species may at time be hard to detect. For example, nowhere is the Carolina pygmy sunfish known to be abundant. In addition, it is essentially an annual species, with adults dying soon after spawning, at an age of 12-15 months. In addition, young are so small that, for a several months, documentation of the species' presence at a particular locality might be almost impossible, at least without preserving specimens. Therefore, negative data at a known locality should be carefully interpreted (P. Shute).
