BUREAU OF FISHEEIES XXIX 



not more than 6,500,000 were distributed in the fry stage, the re- 

 mainder comprising egg shipments or fingeriing fish ranging up to 

 legal size. 



In spite of the fact that the cooperative nurseries created a new 

 demand for close to 4,000,000 trout eggs and fry, the bureau has been 

 able to keep practically up to date with the applications for trout. 

 In many instances it has been possible to furnish greatly increased 

 numbers of fish on the usual applications from territories adjacent 

 to the hatcheries. In most cases average success has been attained 

 in the propagation of warm-water varieties in the Southern States. 

 The Fairport (Iowa) station provided a large number of bass for 

 distribution as a by-product of its experimental work. The in- 

 creased output for the previous year at the Orangeburg (S. C.) station 

 has been maintained. The necessity of transporting rescued fish 

 from the Mississippi River into Montana, Wyoming, South Dakota, 

 and North Dakota was obviated by a splendid output from the 

 Miles City (Mont.) substation, operated in conjunction with the 

 State of Montana. 



RESCUE OPERATIONS 



After the inactivity of the previous year in the Mississippi River 

 rescue field, natural conditions during the fall of 1929 were such as to 

 permit of extensive operations and over 160,000,000 fish were handled. 

 As usual, shipments on applications to other waters amounted to less 

 than 1 per cent of the total number of fish handled. 



COOPERATIVE ACTIVITIES 



^Mierever the l)ureau's activities iiave contact with those of other 

 Federal bureaus or dei)artments, nuitually hol])ful relationshi])s have 

 been established. The Forest SerWce has furnished a detailed sur- 

 vey showing the requirements for restocking waters in all the ]}rincipal 

 national-forest areas as the result of. conferences looking toward the 

 development of a program for meeting these requirements. The 

 National Park Service has worked with the bureau in closer harmony 

 in connection with the creation of new hatcheries and i-earing facilities 

 in both Yellowstone and Cilacier Parks. A bureau em])loyee has been 

 placed in full charge of all fish-cultural work in the ])arks and has been 

 detailed to make surveys of all the im])ortant national-park areas 

 for the i)ur])ose of working out a coherent stocking policy. 



In view of the expansion of fish-cultural work in most of the States 

 there has been a closer liaison between jthose agencies and the bureau. 

 The propagation of commercial species in Michigan, was particularly 

 successful and the whole-hearted cooj)eration afforded by the State 

 department of conservation contributed largely to these results. 

 The State of Virginia is embarking u])on an ambitious fish-cultural 

 program and the bureau has been able to assist in various ways. 

 The construction of an extensive bass-cultural establishment by the 

 State of Arkansas has continued at a ra])id rate under the direction 

 of the bureau's superintendent at Mammoth Spring, Ark. 



The work of restocking with both game -and commercial species 

 has been materially furthered by the harmonious relationships main- 

 tained with the States of Washington, Oregon, Wyoming, Minnesota, 

 Norih Carolina, South ('aroHna,-\r)iiTic, and others. With the coop-
