DURING THE FISCAL YEAR 1907. 9 



cessful operations of the new hatchery in Alaska brought the number 

 of blueback salmon this year to nearly six times as many as were pro- 

 duced in 1906. On the other hand, floods and freshets so interfered 

 with the collection of eggs in Washington and Oregon that the output 

 of chinook and silver salmon fell far behind. There were nearly a 

 third less flatfish this year than last ; but the phenomenal collection 

 of lake trout eggs in 1906 was equaled, and there were large increases in 

 pike perch, white perch, yellow perch, cod, and lobsters; and the shad 

 plants were nearly doubled, through the fortuitous results of storms 

 on the coast which prevented fishing in the lower waters of Chesa- 

 peake Bay and thus permitted fish to reach the spawning grounds. 

 Striped bass, the propagation of which was undertaken three years 

 ago in North Carolina, but has been scarcely more than experimental, 

 make practical showing in 1907, by reason of very successful efforts 

 on the Pacific coast; while pollock, propagated in comparatively 

 insignificant numbers hitherto, are represented by over 86,000,000 

 fry. The yield of whitefish, lake trout, brook, rainbow, and black- 

 spotted trout, and Atlantic salmon was about the usual.
