THIRTY-FIFTH 15IENNIAL REPORT 35 



The Bureau is still in need of a larger supply of Rainbow eggs 

 and definite steps have been taken to increase the number of this 

 species reared and to reduce the number of Loch Leven. During the 

 summer of 1937 thirty thousand Rainbow lingerlings were transferred 

 from the Hot Creek ponds to 'Mt. Shasta and they liave grown excep- 

 tionally well. These fish were derived from fall spawning stock and 

 will undoubtedly make a valual)le addition to the number of Rainbow 

 eggs available in 1989. The supply of this species during the past 

 two years has also been augmented by increased purchases from 

 private dealers. 



During 1987 the rebuilt Prairie Creek and Basin Creek hatcheries 

 were put into full operation. The Central Valleys small mouth bass 

 hatchery and fish rescue headquarters were put into partial opera- 

 tion. This station, although still under construction by the Works 

 Progress Administration, at the end of the biennium operated at nearly 

 full capacity. The small mouth bass produced are being planted in 

 certain selected localities with a view to determining the possibility 

 of establishing these fish. 



The construction of the Central Valleys Hatchery has also made 

 possible an expansion of the fish rescue work in the valley area. 

 During 1987 four crews were operated and a total of 11,500,000 fish 

 were obtained. During 1938 this work was further increased by the 

 addition of two more crews. A detailed list of the fish saved during 

 1987 will be found in the statistical appendix. 



One fish rescue crew was also used in the salvage of trout and 

 salmon in Del Norte and Humboldt counties. It is hoped that it will 

 be possilile to extend the fish rescue work in the north coast area dur- 

 ing the coming biennium.
