BUREAU OF FISHERIES XV 



plete hatching' phint. to each of which an employee of the bureau is 

 detailed for the year to supervise operations. The nurseries are de- 

 voted largely to the culture of trout, which are easier than some other 

 fish to handle under artificial conditions. A satisfactory site for a 

 bass-rearing project is much more difficult to find, the construction 

 of large artificial ponds is expensive, and adult brood fish are hard 

 to obtain. Consequently, few successful bass nurseries have been 

 established. 



COOPERATIOX WITH STATES AND FOREIGN GOVERNMENTS 



By the operation of field egg-collecting stations in Federal reserva- 

 tions, such as the Yellowstone Park, or in State waters, the bureau 

 has been able to secure surplus eggs of various species of trout, which 

 have been turned over to most of the Western States for the bare cost 

 of collection or even gratis. Particularly cordial relations were 

 maintained with the State of North Carolina, and after a survey of 

 the waters in the proposed national park in the w^estern part of the 

 State, the bureau allotted 200,000 rainbow trout as an initial step in 

 improving the fishing. The bureau also reopened a striped-bass 

 hatchery in this State, the only one of its kind there. 



The bureau supervised the construction of a large bass pond estab- 

 lished by the State of Montana on Government-owned land at Miles 

 City. As usual, eggs were incubated by the State of West Virginia 

 at the bureau's White Sulphur Springs station, and a distribution 

 car was lent to that State and to Maryland. In Michigan and Minne- 

 sota, State hatcheries were available for incubating surplus eggs and 

 the bureau was able to furnish extra space for handling State eggs. 



The State of Arkansas is establishing a large fish hatchery, and 

 the bureau helped by detailing an employee to assist in selecting a 

 site and preparing plans. The lending of experienced men has en- 

 abled the States of New Jersey and Connecticut to initiate shad and 

 flounder hatching, while in Florida the artificial propagation of the 

 spin}' lobster was begun under the direction of an employee of the 

 bureau. The usual assignment of fish and fish eggs to various States 

 was made, 104,348,000 having been distributed thus. 



Cooperative operation of a pike-perch hatchery on Lake Cham- 

 plain by the bureau and the States of Vermont and Pennsylvania was 

 continued successfully. The State of INIichigan has made the work 

 of the bureau's hatcheries on Lakes Huron. Michigan, and Superior 

 more effective by putting into effect regulations that oblige commer- 

 <;ial fishermen to supply eggs for propagation and by lending its 

 patrol force, boats, etc.. in handling the eggs. Shipments of i-ainbow- 

 trout and steelhead-salmon eggs or fingerling largemouth blacl'" 

 bass were made to Hawaii, Italy, Germany. Switzerland, Ecuador 

 Peru, and Bermuda, besides top minnows for mosquito-control work. 



The National Park Service has been helpful in the i)rosecution of 

 hatcheiy operations in the Yellowstone Park and (rlacier Park. So 

 far as possible, the Forest Service and the Indian Service have been 

 accommodated with assignments of fish and pggs for stocking waters 

 within their jurisdiction.
