PROPAGATIOX AND DISTRIBUTION OF FOOD FISHES, 19 2 8 387 



containers, or 2,500 carloads. X large proportion of the fry and 

 fingerlings were planted in waters in the vicinity of the hatcheries 

 or released from the rearing stations into streams without resorting 

 to shipment by rail. This is particularly true of the commercial 

 species and rescued fishes. 



Shipments of fish eggs were made to Costa Rica, Cuba, Ecuador. 

 Germany, Peru, and Switzerland. About 95 per cent of the year's 

 output consisted of eggs and fry of the commercial species, and 

 virtually all of these, with the exception of the comparatively few 

 furnished State fish commissions, were planted in the waters from 

 which the eggs were obtained. Included in this classification are the 

 glut herring, whitefish, cisco, salmon, pike, perch, yellow perch, carp, 

 buffalo fish, cod, haddock, and winter fiounder. The species dis- 

 tributed to interior waters are the brook trout, rainbow trout, black- 

 spotted trout, and Loch Leven trout, the smallmouth black bass, large- 

 mouth black bass, crappie, rock bass, bream, and catfish. While the 

 number of other fishes delivered represents but a small percentage of 

 the entire output, at the time of shipment such fish w^ere quite large 

 and the distribution was a difficult problem. Fry of the commercial 

 species are carried 50,000 to 100,000 to the pail, while not more than 

 one hundred and fifty 3-inch fish can be carried in one of the regula- 

 tion containers. 



The trout distribution has become exceedingly heavy at the bureau's 

 trout-producing stations, due to the establishment of a large number 

 of cooperative nurseries in a number of the States. Small trout are 

 delivered during May and June and are reared until they are 3 or 

 4 inches in length, when they are planted in suitable local waters. In 

 addition to the general distribution to applicants during the spring 

 and early summer, approximately 15 carloads of trout were delivered 

 to cooperative projects in Pennsylvania, West Virginia, New York, 

 Virginia, Minnesota, and Wisconsin. 



The following table shows in summarized form the distribution of 

 fish and fish eggs during the fiscal year to applicants in the United 

 States and its territories. It also shows the plants of fish made by 

 the bureau in public waters of the country in connection with -the 

 propagation of commercial fishes and the salvage of fish from 

 temporary public lands.
