The Sacramento perch, Archoplites interruptus (Girard), is a relict centrarchid, historically found west of the Rocky Mountains. Since 1960, this species has been introduced into waters east of the Rocky Mountains. Sacramento perch are euryhaline and adaptable to inland mineral waters whose high salt content precludes the establishment of other game fishes. The species has survived and reproduced in chloride‐sulfate waters with salinities near 17,000 ppm. Survival of Sacramento perch has not been recorded in sodium‐potassium carbonate waters exceeding 800 ppm in total alkalinity. Recent introductions have been made in Arizona, Colorado, Nebraska, New Mexico, Soath Dakota, and Texas. The annual growth rate of Sacramento perch is good in the larger alkaline and saline lakes where interspecific competition is limited to a few species. Natural propagation is not difficult and can be obtained in small rearing ponds. Aside from releases into mineral waters devoid of game fishes and hatchery pond propagation, fisheries agencies have shown little concern for the management of Sacramento perch in North America.
