To hatch 20,000,000 whitefish eggs 30 years ago was considered some- 

 thing remarkable, but now, of course, it would be considered practically 

 a failure. I think at that time there were not to exceed seven or eight 

 hatching stations in the whole United States operated by the Federal 

 Government, perhaps not that many. I mention these facts only to 

 call attention to the remarkable progress made in practical fish culture 

 in the past 30 years. 



Mr. Frank N. Clark, Northville, Mich. : I do not believe that we 

 individually realize what is being done in the way of turning out fry, 

 I mean turning out the living, swimming animals in the water. That is 

 why I said what I did about pollution. When I first commenced work 

 on the fish commission we had a camp at Mt. Vernon, and if we turned 

 out 600,000 or 800,000 shad we thought we were doing wonders, and 

 when we first commenced taking trout and whitefish on the Great 

 Lakes I remember that with 500,000 lake trout we thought we were 

 doing wonders. Now our station alone takes 71,000,000 and various 

 states are doing a thousand times what the United States did in the 

 first year. Taking the states and the nation together, we are turning 

 out an enormous quantity of fry. When you get up to 6,000,000,000 or 

 8,000,000,000, that means a lot.
