Fish Producing Nations in 1959 and Recent Estimates of 



Their Populations 



Including shells of molluscs. 



Present expansion is manifested in the development of the large stern 

 trawler by the United Kingdom and its expanding use by the USSR and 

 other nations; the increasing growth in size and range of tuna vessels, 

 particularly of Japan; and the extensive use of motherships long used 

 in Antarctic whaUng but heretofore only sporadically in the fisheries. 

 No part of the earth is outside the range of present-day fleets. 



The present challenges faced by nations in reahzing the full food 

 potentials of the ocean are : increased efficiency in harvesting the natural 

 stocks; their scientific management to assure high and sustained yields; 

 equitable division of such yields among nations; and cultivation to 

 increase the natural food fish potentials of the enclosed or enclosable 

 bodies of fresh and salt waters of the world.
