PROPAGATION AND DISTRIBUTION OF FOOD FISHES, 1934 409 



this ix)iiit extensive (leveloj)nient has been under way through a 

 P. \\'. A. allotjnent, tlie assisjtunent of rehef hil)or, and tlie utilization 

 of C\ C. (\ \v.)rkers. Ajnonij; the aceojnpHshnients were the provision 

 for a (h)niesti(' water supply, the extension of the cniial and pipe-line 

 systems and the construction of a new i)ower house and sui)ply canal. 

 Another important ])roject was the rebuildint; of Diversion Pond, 

 one of the trout ])onds which was washed out durini; a period of heavy 

 rainfall. Numerous other jobs incidental to the development of this 

 extensive ])roject were also prosecuted durine; the year. 



In Maine the (Irand Lake Stream auxiliary was closed durin<; the 

 fv)repart of the iiscal year and the responsibility of its operation 

 assumed by the Maine Department of Inland Fish and (iame. All 

 lish on hand ajuountinii; to over 500,000 landlocked salmon and brook 

 trout were distributed prior to the transfer. The State of Maine 

 under a working agreement furnished the Bureau with a limited 

 number of landlocked salmon eggs which were formtM'ly collected at 

 this point. 



At the main station located at Craig Brook, operations were success- 

 ful and the collection of brook-trout eggs amounting to 7,385,000 

 exceeded all previous takes. A considerable amount of repair work 

 was done on the ponds and drainage system, much of it being required 

 by the severe winter which caused extensive damage. In contrast 

 witli previous years the services of a fish car were not utilized in dis- 

 tributing the output of fish. The fingerling salmon and trout were 

 largely planted by inducing applicants to receive them at the hatcherj'. 



COMBINATION TROUT AND POND-FISH STATIONS 



Owing to the overlapping in the natural range of the trout and 

 warm-water species such as bass, a number of hatcheries are called 

 on to supply fish of both groups. Consequently, where natural 

 conditions permit, the hatcheries are developed so as to propagate the 

 two different types. However, as a rule, a hatchery suitable for the 

 propagation of trout does not offer optimum conditions for breeding 

 warm-water fish and as a consequence the latter activity is more or 

 less supplementary and the output of bass, sunfish, etc., at the com- 

 bination stations is usually of limited numbers. 



The White Sulphur Springs (W. Va.) station duplicated its success 

 of the previous year and handled approximately 5,400,000 trout eggs, 

 producing an output of fish for distribution of over 3,000,000. Co- 

 operative arrangements with the ^Vest Virginia (Conservation Com- 

 mission were again maintained, and the Bureau incubated 1,000,000 

 brook trout eggs for that agency. The output of warm-water species 

 was improved in that the fish distributed were of larger si/.e. Some 

 improvements in the nature of widening and straightening the creek 

 channel through the station grounds, and painting the station build- 

 ings were undertaken. 



The Wvtheville (Va.) station now functions as an important unit 

 in the production of rainbow trout eggs, furnishing approximately 

 2,750,000. The output of trout from this station and its auxiliary 

 seasonal rearing stations is eminently satisfactory. The bulk of the 

 production of pond fish consisted of bream and rock bass. An electri- 

 cal refrigerating system was installed as well as an electric pumping 

 system for filling shipping cans. Aside from painting the station 

 buildings, 1,000 feet of water supply pipe line was replaced.
