XXIV REPORT OF THE COMMISSIONER OF FISHERIES 



salvage fishes in Louisiana or in the vicinity of Friars Point, Miss. 

 The river did not reach a sufficiently high stage to overflow the 

 borrow pits. During the season many of the fish returned to local 

 waters and were inoculated with the glochidia of fresh-water 

 mussels. 



PROPAGATION OF FISHES IN INTERIOR WATERS 



Very notable results were attained in the Meadow Creek (Mont.) 

 field in the collection of the eggs of the Loch Leven trout. The 

 large collections made would seem to indicate that the waters of 

 Montana are very well suited to this species. Advantageous ex- 

 changes of eggs of other species of trout were made with many State 

 fish and game commissions. In the Colorado and Utah fields 

 good collections of brook-trout eggs were obtained. Virtually all of 

 the bureau's fish-cultural stations that handle trout have enlarged 

 their facilities so that greater numbers of fish may be held until 

 they reach the large fingerling stage before shipment. Fish-cultural 

 operations in the Yellowstone Park field were somewhat curtailed 

 on account of prevailing high waters during the spawning season 

 of the black-spotted trout. Many apparently spawned on the 

 beaches and did not ascend the streams as usual. 



COMMERCIAL FISHERIES AND FISHERY INDUSTRIES 



REVIEW 



The number of persons engaged in the fisheries and fishery indus- 

 tries of the United States and Alaska exceeds 191,000; the invest- 

 ment amounts to about $202,000,000; and the annual sales of fishery 

 products by fishermen is about 2,881,000,000 pounds, valued at about 

 $97,000,000; the output of canned fishery products has an annual 

 value of over $80,000,000; and the production of by-products is 

 valued at about $15,000,000. 



Conditions in the fisheries during 1925 compare very favorably 

 with those of the past few years. Vessel landings at the New 

 England ports were above normal in quantity, due to unusually 

 large mackerel and haddock landings. Although the average prices 

 declined slightly, the total value of products was substantially 

 greater than in 1921. Seattle landings were below those of 1921 in 

 quantity and value. The canning industry produced greater quan- 

 tities of nearly all varieties of canned fishery products, the total 

 value being considerably higher than in recent years. By-products 

 also were produced in larger quantites and were of greater value. 

 Exports of edible fishery products showed an upward trend, while 

 imports for consumption were slightly lower. 



Through its division of fishery industries the bureau has been 

 of direct service to the fishery industries by its collection and publi- 

 cation of fishery statisics, its technical research, and its dissemination 

 of practical information to the industry. 



Statistics on landings of fish at the ports of Boston and Gloucester, 

 Mass., Portland, Me., and Seattle, Wash., were collected and pub- 

 lished monthly. Statistics of the cold-storage holdings of fish were 

 collected by the Bureau of Agricultural Economics in the Depart- 

 ment of Agriculture and were published monthly by the Bureau
