Abstract : In 1980, the Bureau of Reclamation's Division of Research, in a cooperative agreement, between the Reclamation's Lower Colorado Region, U.S. Fish and Wildlife Service, Coachella Valley Water Users Organization, Imperial Irrigation District of California, and three State of California agencies, initiated a study with hybrid grass carp to evaluate their effectiveness in controlling aquatic weeds in test canals and their effects on the aquatic environment. The Division of Research staff's responsibility in these studies was to determine the effectiveness of the hybrid fish in controlling aquatic vegetation. The summary of progress made during the 3-year study is presented herein. The other cooperators were responsible for development of fish handling and management techniques and determining effects on aquatic environment (reported elsewhere).
