1372 BUI^I^ETIN OF THE BUREAU OF FISHERIES. 



THE SPECIES CULTIVATED. 



At the end of the first ten years of the Bureau's existence the fishes that 

 were being regularly cultivated were shad, carp, chinook salmon, Atlantic sal- 

 mon, landlocked salmon, rainbow trout, brook trout, and whitefish, in addition 

 to which the propagation of several others had been undertaken experimentally. 

 The list now is six times as long, and the annual output is ten times the aggregate 

 for the ten-year period ended in 1881. The main energies are devoted to the 

 important commercial fishes — shad, whitefish, lake trout. Pacific salmons, white 

 perch, yellow perch, cod, flatfish — and the lobster, which are hatched in lots of 

 many millions annually. More widely popular, however, are the distributions 

 of the fishes of the interior waters which are generally classed as game fishes. 

 Although representing only about 10 per cent of the output of the hatcheries, 

 this feature of the work is very important, for it supplies choice kinds of fish for 

 public rivers, lakes, and ponds, and for fishing preserves and private ponds and 

 streams in all parts of the United States. The fishes most in demand for these 

 purposes are the landlocked salmon, the different species of trout, the grayling, 

 the basses, the crappies, the sunfishes, and the catfishes, but various others also 

 are handled. Following is a classified list of the native fishes artificially propa- 

 gated during 1908:
