PROPAGATION AND DISTRIBUTION OF FISHES FROM HATCH- 

 ERIES AND FISHERY RESOURCE MANAGEMENT FOR FY 1980 



INTRODUCTION 



This report on fishes and fish eggs distributed by national fish 

 hatcheries for the period October 1, 1980, to September 30, 1981, is a 

 continuation of a series of publications issued since 1872. Records of 

 hatchery outputs were published in the annual Commissioner's Report of 

 the U.S. Commission of Fish and Fisheries through 1903 and in the 

 Annual Report of the Commissioner of Fisheries of the U.S. Department 

 of Commerce, until 1940. From 1941 through 1962, these tabulations 

 were presented as "Statistical Digest". Beginning in 1963, these reports 

 became known as the "Fish Distribution Report". Report No. 2 for 1965 

 and 1966 established the fiscal year as the period of coverage. In 1976, the 

 fiscal year time frame was changed from July through June to October 

 through September. Report No. 11 recorded fish distribution for the 

 period of July 1, 1975 through September 20, 1976, which included the 3 

 month transition quarter — July, August and September 1976. All future 

 fish distribution reports will coincide with the October through 

 September fiscal year. 



The Hatcheries and Fishery Resource Management system produces 

 primarily salmon, trout, catfish, pike, bass, and sunfish. Several 

 additional species of fish are produced and collected for use as test 

 animals in various research projects. 



The goal of the Fish and Wildlife Service is to conserve the Nation's 

 freshwater and anadromous fishery resources for the benefit of the 

 people. Distribution of fish from the Federal hatchery system assists in 

 meeting this goal in accordance with the following objectives: 



a. To restore and/or maintain existing freshwater and anadromous 

 fishery resources in suitable streams, rivers or lakes of the United States. 



b. To increase the fisheries by restoring destroyed or depleted fishery 

 resources. 



c. To create greater fisheries by upgrading existing fish populations, 

 developing new bodies of water, and introducing new species. 



d. To aid States in the management and development of fishery 

 resources. 



e. To protect the Nation's fisheries by limiting the introduction or 

 distribution of diseased fish and their attendant pathogens. 



f. To control the introduction and population levels of exotic species 

 damaging to the fishery resources or aquatic ecosystem.
