In some fields unfavorable weather conditions interfered with the 

 output of the Pacific salmons. The propagation of the marine 

 species of the Atlantic coast assumed very large proportions, and 

 a "record was established in the egg collections of one species — the 

 winter flounder — of which 2.404,887,000 were secured by the three 

 stations engaged in the work. With the exception of two species — 

 whitefish and carp — the egg collections and output of the various 

 commercial species of the Great Lakes were increased slightly over 

 the corresponding figures for 1923. A comparison of trout egg 

 collections with those of the preceding year shows a decrease in 

 numbers for certain species. The most noticeable increases over 

 last year's record occur in the collections of blackspotted trout eggs 

 in the Yellowstone Park, and of Loch Leven trout eggs, as a result 

 of the first year's operations of a new field station in the Madison 

 Valley in Montana. 



The most important fish-cultural operations of the bureau are 

 those relating to the maintenance of the commercial fisheries, the 

 welfare of which must be considered of paramount value, because 

 they have a direct bearing on the extent of the country's food sup- 

 ply. In this branch of its activities the bureau's sole source of 

 egg supply is the fish that are taken for the markets, and as such 

 eggs would otherwise be an entire loss it can be readily seen that
