Fish rescue trap designed by G. R. Holman. The whole flow of a small tributary stream which has dried 

 up in its lower portion is diverted into a mesh box placed at the terminal end of the flow. The down- 

 stream migrating fingerlings are trapped and removed each morning. Fish rescue is an incidental pro- 

 gram of the crew working in the North Coast area. During May and June, 1952, a total of 19,400 



steelhead and 3,998 silver salmon was rescued. 



WARM-WATER FISHES 



The reproductive potential of the warm- water fishes (principally the 

 black basses, sunfishes, and catfishes) is generally recognized to be so 

 great that stocking for maintenance is unnecessary, and may actually 

 be harmful. The warm-water fisheries program of the Bureau of Fish 

 Conservation is consequently directed toward finding ways of increasing 

 production in existing waters and creating new fisheries.
