20 BEPOET OF THE COMMISSIONER OP FISHERIES. 



tived by the States' indifference, and the necessity for Federal control 

 of interstate waters in the interest of the fisheries is thus again 

 forcefully illustrated. 



RECOMMENDATIONS. 

 NEW FISH-CULTURAL STATIONS. 



The growth of the fish-cultural branch of the Federal fishery 

 service and the increasing demands for food and game fishes necessi- 

 tate the establishment of additional hatcheries from time to time. 

 At present the greatest need exists in the Mississippi Valley and 

 Southern States, for the cultivation of commercial fishes adapted for 

 culture in ponds and small water courses, and it is strongly urged 

 that early provision be made for a limited number of hatcheries in 

 those regions. 



INCREASED FACILITIES FOR RESCUING FISH FROM OVERFLOWED LANDS. 



This important work, which in some respects is more beneficial 

 than artificial propagation, is susceptible of great expansion and 

 may be made the means of saving millions of most desirable food 

 fishes that are now lost each year. To this end there should be estab- 

 lished in convenient parts of the Mississippi Valley several stations 

 with large pond capacity for the retention of rescued fishes pending 

 their distribution to suitable waters. 



NEW FISH-CULTURAL EXPERIMENT STATION. 



It is urgently recommended that there be established within con- 

 venient distance from Washington a composite station for pond and 

 river fishes, which shall be operated chiefly for the purpose of de- 

 veloping and improving methods and for the solution of the numer- 

 ous problems that are continuall}^ arising in the course of the Bureau's 

 work. Such a station as is desired was in a measure afforded by the 

 Fish Lakes in Washington ; but since their abandonment the Bureau 

 has had no adequate facilities for experimental work under executive 

 supervision, and the settlement of various important questions has had 

 to be deferred, for it is not possible to carry on the necessary investi- 

 gations at the established hatcheries because, in addition to adverse 

 conditions for the experiments, the regular and required hatchery 

 work would be interfered with and the output of fish curtailed. The 

 expense of such a station, with the additional expert services the work 

 requires, would be more than repaid by the increased efficiency of the 

 fish-cultural wprk and the greater economy of administration. 



FEDERAL CONTROL OF INTERSTATE FISHERIES AND FISH TRADE. 



In the present far-reaching movement for conservation of natural 

 resources, the necessity for uniform and adequate fishery protective 

 laws covering interstate waters has been emphasized anew. It is 

 accordingly believed that in view of the lack of concerted action on
