Downing. — Production and Destruction 35 



Comparative Waste. — During the fall of 1911, in the district 

 where the fish cultural work of the Ohio stations are conducted, 

 there were taken 945,010 pounds of whitefish averaging about 

 2% pounds each, or a total in numbers of 378,004 fish. Had the 

 same number of pounds been taken of the undersized fish running 

 three fish to the pound, it would have required 2,835,030 fish, 

 which would mean a destruction of 2,457,026 fish, and if one half 

 of these were females, as we have a right to suppose they would be, 

 then there would have been a destruction of 6,087,575,000 eggs.
