23 



production was 4, 7 70, .'^5 5 .000, of which a,s72,2 18,000 were fry, 267,- 

 38S,()00 were fin<2:erlin<>-s, yearlin<j:s, and achilts, and r)30,74{),0()0 were 

 fertilized and viahU^ eir^s. Important species whose output was 

 lar<rer than in the previous yQnv were catfish, butfak)fish, wliitefish, 

 chinook sahnon, chum salmon, steelhead salmon, rainhow trout, 

 blackspotted trout, irraylin^, crappie, sunfish, and cod. There was a 

 reduction in the output of shad, cis'o, pike perch, yellow perch, pol- 

 lock, and winter flounder. The net decrease in output was about 

 1,105,000,000, of which about 1,050.000,000 represented the winter 

 flounder. 



Untoward conditions tliat influenced the fish-cultural work were 

 the partial disorganization of the field force, the increased cost of 

 operations with no increase in available funds, and unfavorable 

 weather durin^: the ep:or-layino: periods. A very serious epidemic 

 amonfr brook trout in Xcw Knoland hatcheries materially reduced 

 the output of that species. 



Followinof is a summarized statement by species showinti; the 

 number of e^y^s, fry, and adults, yearlings, and firigerlings distributed 

 during the fiscal year 1920 :
