EGG COLLECTIONS 



As would be expected from the fact of an increased output for the 

 fiscal year, egg collections were materially in excess of those for 

 1929 — the increase being close to 1,000,000,000. Collections of eggs 

 of the cod, pollock, winter flounder, pike perch, whitefish, black- 

 spotted trout, and other species of trout were important factors in 

 accounting for the enlargement. Several new field stations for the 

 collection of eggs from wild trout were opened during the year, 

 notably in Colorado and New Mexico. Loch Leven trout egg collec- 

 tions from the Madison River, Mont., eclipsed previous records. 

 Further expansion of the output from station brood stock kept the 

 purchase of comihercial trout eggs from private hatcheries at a 

 minimum; practically the only eggs secured from this source being 

 utilized to stock cooperative hatcheries, which represented a new and 

 additional demand. Where the bureau is able to increase its collec- 

 tions, both of the trout and commercial species, beyond the hatching 

 or rearing capacity of its own hatcheries, the surplus is assigned to 

 State hatcheries, either for their outright disposal or for hatching 

 and rearing for subsequent distribution by the bureau.
