XYl RETORT TO THE SECRETARY OF COMMERCE 



UPPER MISSISSIPPI -WILD-LIFE REFUOE 



Contemporary with the acquisition of sufficient hmd, joint regu- 

 lations for the administration of the Upper Mississippi Wild-Life 

 Refuge, created under act of June 7, 1924:, were issued by the Secre- 

 tary of Agriculture and the Secretary of Commerce. The bureau 

 has been acquiring boats and equipment for conducting the necessary 

 work, and an exhaustive biological survey of the possibilities of the 

 area in a fish-cultural way has been begun. It is the purpose of the 

 bureau to propagate warm-water fishes in this region and thereby 

 avoid the necessity of distributing rescued fish from the overflowed 

 regions. Several sites for bass ponds have been selected and they 

 will be developed as soon as possible. 



PROPAGATION OF PACIFIC SALMONS 



The success of propagating the Pacific salmons has varied con- 

 siderably. A larger output of some species at some of the stations 

 was offset by reductions at other points, so that the total production 

 of 139,719,600 was about normal (about 19,000,000 more than last 

 year). All of the salmon-propagating stations are rearing finger- 

 lings to capacity. One million sockeye fingerlings were fed at the 

 Lake Crescent station of the State of Washington and later were 

 released in the lake. In the Puget Sound region, chum-salmon eggs 

 were available beyond the capacity of the hatcheries. 



MARINE SPECIES OF THE ATLANTIC COAST 



The output of 5,793,481,000 cod, haddock, pollock, and winter 

 floynders at the New England stations exceeded that of last year. 

 Although pollock and winter flounder egg collections declined 

 sharply, there was an increase of approximately 50 per cent in the 

 cod-egg collections. Marine work includes not only the incubation 

 of eggs and the distribution of fry, but also the planting of fertilized 

 eggs on inaccessible offshore spawning grounds. The propagation of 

 commercial marine species is a by-product recovery in the truest 

 sense, as a very large proportion of the eggs is secured from fish 

 caught for market, where the eggs would be wasted. The Woods 

 Hole station has resumed the hatching of mackerel Avith considerable 

 success. 



ANADROMOUS SPECIES OF THE ATLANTIC COAST 



The output of shad increased over 100 per cent and amounted to 

 48,031,000. The shad run in the Potomac River was the heaviest 

 in years, and the output from the Edenton (N. C.) station also 

 showed quite an increase over those of recent years. About 7,000,000 

 striped-bass eggs were taken in the Roanoke River and hatched. 

 About 1,500,000 Atlantic-salmon eggs w^ere obtained from Canada 

 for the Craig Brook (Me.) station. The salmon fingerlings planted 

 from this station in recent years seem to have been effective in 

 slightly increasing the abundance of this fast-disappearing species. 

 The output of approximately 150,000,000 yellow perch w^as about 

 normal. The collection of glut-herring eggs at the Edenton station 

 also rose from 5,000,000 to 223,000,000.
