XXX REP0I5T TO THE SECRETARY OF COMMERCE 



• 



oration of the Indian Service and the State of Nevada the bureau took 

 over tlie fish-c\dtnral work in connection with the propagation of 

 bhick-spotted trout at Pyramid Lake. An employee of the bureau 

 was detailed to ])articipate in a survey of the inLand hatcheries of 

 the State of Ohio. Additional requests for assistance from a num- 

 ber of other States could not be fully met due to lack of facilities. 



The cooperative nursery program whereby sportsmen's associations 

 operating hatcheries or nursery ponds receive fish from the bureau's 

 hatcheries for rearing to larger size has been standardized and con- 

 stitutes a routine activity. During the fiscal year a few of the older 

 nurseries discontinued operations for various reasons and additional 

 ones were taken on, so that the total of 123 now conducted represents 

 an increase of approximately 10 over the previous year. These organ- 

 izations were furnished a total of 3,827,700 fish and eggs, largely of 

 the trout species. In view of this heavy demand upon the bureau's 

 trout production it has been necessary to exercise greater care in 

 establishing new nurseries and to require that natural facilities be 

 proper and adequate for the purpose. This has necessitated refusal 

 to coo})erate in some instances and termination of the cooperative 

 arrangement already existing in others. Eftbrt has been made to 

 augment the number of bass nurseries and to extend the field of these 

 operations into States and sections previously not touched to over- 

 come the present "spotty" distribution in a few States. 



In a number of States where the bureau conducts no cooperative 

 nurseries the States are carrying on this work very successfully and 

 there is little or no demand for the bureau's participation. Two of 

 the establishments in New York and Pennsylvania are complete 

 hatchery units incubating eggs and carrying on all the functions of a 

 regular hatchery, with an em])loyee of the bureau in. charge. 



It is believed that while the assignment of fish to individual nur- 

 series may be decreased and the establishment of new units may fail 

 to keep pace with the rate set during the earlier years, the output of 

 large-sized fish will be materially increased by the standardization 

 of procedure, 



VESSEL NOTES 



The Albatross II continued her scientific research work, with head- 

 quarters at Woods Hole, Mass. During the year the vessel was 

 engaged in operations between Cape Ann, Mass., and Cape Hatteras, 

 N. C., with the exception of one cruise between the continental 

 shelf and Bermuda, which was discontinued on account of pump 

 trouble developing. Oceanographic stations numbering 273 were 

 made between Cape Ann and Cape Hatteras, vaiying in distance 

 from a few miles to 180 miles offshore. At convenient times between 

 cruises throughout the year the vessel underwent various repairs at 

 the Boston Navy Yard. The vessel cruised 13,017 miles. 



The steamer Shearwater was engaged in fish-cultural work at the 

 Put in Bay (Ohio) station from November 1 to December 15 and 

 from March 1 to June 1. In addition to this regular work she was 

 engaged in fishery investigations on Lake Erie. 



The steamer Phalarope was employed as usual as a tender at the 

 Woods Hole biological station, except for a period of a few weeks in 

 the spring when she was at the Fort Humphreys station on the 

 Potomac, in connection with shad inyestigations.
