Nonindigenous Occurrences: Established in the lower Colorado River, and Imperial Lake bait pond in Arizona; and the lower Colorado River, Taylor Lake Pond, and Lake Havasu Pond in California (Minckley 1981; Hayden et al, 1963).

Ecology: The riverine grass shrimp is always associated with some sort of aquatic cover and is most abundant in dense beds of submerged aquatic vegetation (Hayden et al., 1963).  They are an important food source for many fish species. 

Means of Introduction: The California Dept. of Fish and Game requested shrimp specimens for introduction into the food chain in the lower Colorado River.  The shrimp were supplied by the FL Game and Fresh Water Fish Commission.  About 225 specimens were planted in Lake Havasu pond on August 27, 1958.  About 1,000 specimens were planted in 3 ponds in the Imperial National Refuge on November 1, 1958.  The 3 ponds were: Taylor Lake pond, Picacho pond, and Imperial Camp bait pond.  The CA Dept. of Fish and Game and the AZ Game and Fish Dept. retuned to the sites during the spring and summer of 1962 to determine the status of the shrimp populations.  Shrimp were found in all sites except the Picacho pond.  It was hypothesized that the shrimp did not survive in Picacho pond sue to intensive fish predation.  The Imperial Camp bait pond had the largest established population. 
In January and Marsh of 1963, 1,100 shrimp were taken from the Imperial Camp bait pond and transplanted into 7 sites:  Branson's Resort (AZ), Marina Village (AZ), Lost Lake Camp in Alligator Slough, backwater below the Palo Verde Weir (AZ), the Palo Verde Drain (west side), Lake Havasu, and Havasu Landing lake pond (Hayden et al., 1963).
