1374 BULLETIN OF THE BUREAU OF FISHERIES. 



the nature of the operations to be conducted and the topographical conditions, 

 and the work of constructing buildings and ponds is usually done by contract. 

 Sometimes, however, the Bureau takes direct charge of construction, as in the 

 case of the salmon hatcheries in Alaska. 



The usual buildings at a fish-cultural station are the hatchery proper, a 

 residence for the superintendent and his family, and necessary outbuildings. 

 At some stations there may be also power house, foreman's or fish-culturist's 

 dwelling, mess hall, and stable. The superintendent's and other quarters are 

 furnished gratis, but station employees provide their own subsistence. 



All sections of the country are now familiar with government fish-cultural 

 work. In addition to the regular hatcheries, with their permanent personnel 

 and living quarters, there are maintained numerous auxiliary hatcheries or 

 substations which from the nature of their work do not require a permanent 

 force and are therefore, for economic and administrative considerations, operated 

 as adjuncts of near-by hatcheries. Some of the auxiliary stations, however, 

 have more extensive operations than the hatcheries with which they are con- 

 nected, and such will doubtless in time be made regular stations. There is 

 also another class of stations, known as field or collecting stations, which serve 

 as temporary headquarters for parties engaged in obtaining eggs from wild 

 fishes. In 1908 the fish-cultural work was conducted in 27 States and Terri- 

 tories at 55 hatcheries and subhatcheries and 64 field stations. 



While marine operations have been conducted from time to time at various 

 places on the Atlantic coast from Maine to Florida, and have been addressed 

 to a large number of species, the only permanent marine hatcheries are in Maine 

 and Massachusetts, with the species handled at each as indicated in the 

 following table. The places shown under each station are the centers of egg- 

 collecting operations. Other sea fishes that have in previous years been arti- 

 ficially propagated and may again come under the hand of the fish-culturist 

 are the haddock, the scuppaug, the sheepshead, the sea bass, the mackerel, 

 and the squeteague, some of which were hatched on the steamer Fish Hawk in 

 Chesapeake Bay and Florida.
