PROPAGATION" AND DISTRIBUTION OF FOOD FISHES, 192 8 353 



SHIPMENTS TO FOREIGN COUNTRIES 



The bureau frequently receives requests from foreign governments 

 for fish or eggs for acclimatization in their waters. Whenever it 

 seems possible that our fishes may become established and eggs or 

 fish are available the bureau endeavors to send an assignment suffi- 

 ciently large to become the nucleus of a breeding stock. The top 

 minnow, Gambusia, has been in great demand for mosquito-control 

 work in foreign countries. Shipments of this fish to Italy and 

 Bermuda were reported to have arrived in good condition. Follow- 

 ing is a list of shipments made during the past year in response to 

 formal diplomatic requests.

PRODUCTION AT STATIONS AND SUBSTATIONS 



The output of fish and eggs cited above was derived from 38 main 

 stations and 35 substations or auxiliaries. Many of the latter are 

 operated during part of the year only with a force detailed from 

 one of the main stations. A few of the substations, however, con- 

 stitute plants almost as large as the headquarters station and are 

 listed as auxiliaries for administrative reasons only. The roster of 

 the bureau's stations shows that the location of the Federal hatch- 

 eries is such that many sections can not be served except at heavy 

 expense for the transportation of fish. The nature and extent of 

 operations at these agencies is indicated in the following table:
