U. S. BUEEAU OF FISHERIES 



REPORT OF FISH FOOD USED AT THE WYTHEVILLE (VA.) STATION 



DURING JUNE, 1924 



The appended table shows the amount of fish food required at one 

 of the bureau's stations for a period of 30 days, the cost of feeding a 

 specified number of fish of several species, and the cost for food per 

 1,000 fish of the species mentioned. 



A comparison of this information with the results of feeding fish of 

 the same species at other stations of the bureau shows a wide varia- 

 tion in the cost per 1,000. At certain stations having a mean water 

 temperature 10° higher than that indicated above, the cost of feeding 

 the same kind of food was much higher. 



COMMERCIAL FISHES 



Among the more important commercial fishes propagated by the 

 bureau during the fiscal year 1924 were the salmons of the Pacific 

 coast, the whitefish, cisco, lake trout, and pike perch of the Great 

 Lakes, the carp in the Lake Erie region, such marine species as the 

 cod, haddock, pollock, and flounder, the buffalo fish in the Mississippi 

 Valley region, and such anadromous fishes of the Atlantic coast as 

 the shad, glut herring, and Atlantic salmon. 



PACIFIC SALMONS 



The outcome of fish-cultural operjations at the salmon stations on 

 the Pacific coast shows a considerable decrease as compared with 

 that in 1923. The shortage was caused in part by lack of funds to 

 prosecute the work to its fullest extent in some fields, while in other 

 sections it is attributable to unfavorable weather conditions during 

 the spawning season. 



AFOGNAK (ALASKA) STATION 

 [F. R. Lucas, Superintendent] 



In view of the exceptionally small number of sockeye salmon that 

 ascended to the spawning grounds adjacent to the Afo^nak station 

 in July, 1923, it was deemed advisable to defer active salmon propa- 

 gation for the period of one year and devote all available funds to 

 extensive repairs, of which the station was in great need. By reason 

 of this decision the output of the year was limited to a small number 

 of fingerling salmon carried over from the previous year's stock, and 

 all sockeyes making their appearance during the summer were given
