Taxonomic Comments
The only living member of the genus; the most "primitive" living member of the Centrarchidae (Lee et al. 1980).

Rank Reasons
Formerly widely distributed and common in much of California; now restricted to just a couple remaining native populations in California, which are small but persistent; native habitat is dominated by introduced species, which threaten Sacramento perch through competition and predation; reasonably secure in several watersheds outside native range. Based on native populations, rank would be G1 (G2G3 if introduced populations are considered).
Range Extent Comments
The Sacramento perch is only native centrarchid west of the Rocky Mountains. It was originally widely distributed throughout the Sacramento-San Joaquin drainage, in the Pajaro and Salinas rivers, and in Clear Lake (Lake County), California (Moyle 2002). Persisting native populations exist in Clear Lake (small population) and Alameda Creek (in gravel pit ponds adjacent to the creek and in Calaveras Reservoir) (Moyle 2002). However, the species has been introduced in other locations within the native range (often upstream of native habitats) (Moyle 2002), and in several areas outside the native range in California, including the upper Klamath basin (California and Oregon), Pit River watershed, Walker River watershed, Mono Lake watershed, and Owens River watershed; it may also persist in Sonoma Reservoir (Moyle 2002).

The species has been introduced and currently is established in Nevada (several drainages) and Utah (Garrison Reservoir) (Moyle 2002). Introduced populations in several other states apparently no longer exist (Moyle 2002).
Occurrences Comments
This species is represented by only a couple remaining native populations, plus several introduced populations that may be reasonably secure (Moyle 2002). Most introduced pond and reservoir populations are not expected to persist over the long term because of changing conditions (Moyle 20020.
Threat Impact Comments
Formerly this fish was widespread and abundant in California, but the population declined rapidly probably due to factors such as habitat destruction, egg predation by non-native fishes, and interspecific competition with introduced centrarchids, especially black crappie; competition may be the most important cause of the decline (Moyle 1976, 2002). Most introduced populations are isolated and vulnerable to genetic bottlenecks and extirpation.
Ecology & Habitat

Habitat

Native habitat included sloughs, sluggish rivers, and lakes with beds of rooted and emergent vegetation; now this fish is found mostly in warm, turbid, moderately alkaline reservoirs or farm ponds, generally where other centrarchids are absent (Moyle 2002). This fish is tolerant of a wide range in water turbity, temperature, salinity, and alkalinity, and large populations may occur in shallow, turbid reservoirs with no aquatic plants (Moyle 2002). In moderately clear water, young stay in or close to submerged vegetation in shallow areas (Moyle 2002). Prior to spawning, males establish small territories in shallow areas (20-75 cm) heavily vegetated with aquatic macrophytes, filamentous algae, or other cover (Moyle 2002). Eggs are deposited in shallow depressions constructed by males (Moyle 2002).

Reproduction

Sexually mature in 2nd or 3rd summer. In California, spawning occurs late March-early August, peak in May-June; timing of breeding depends on temeprature. Spawning begins in mid-June in Pyramid Lake, or when water temperature reaches 68 F. Eggs hatch in about 50 hours at 21.7 C. Male remains with eggs until hatching and for about 2 more days following hatching (Moyle et al. 1989).
