and salt water with respect to shrimp, for example. It is a field that 

 other nations have developed more rapidly than we have, but we are 

 coming to it, Mr. Rogers. 



Mr. Rogers . I would like to know what program you have developed 

 and what you plan to do, particularly with lobster or shellfish, crab, 

 or shrimp. 



Dr. Cain. Oysters ? 



Mr. Rogers. Yes. 



Dr. Cain. We will report on that.

Fish Farming Programs 



A number of Bureau of Commercial Fisheries programs are directed toward 

 developing agricultural techniques to raise under controlled conditions, oysters, 

 clams, lobsters, shrimp, pompano, and other marine finfish. We have developed 

 artificial culture methods for oysters and clams, some of which are being tested 

 on a commercial scale. Knowledge about habitat requirement for lobsters is 

 being accumulated and promising beginnings have been achieved by successfully 

 spawning and rearing shrimp. We now can spavin and rear through juvenile 

 stages several species of marine finfish and field tests to raise pompano in ponds 

 are progressing well. 



True fish farming of most marine species, however, still is in its infancy in this 

 country. Much more basic knowledge is needed of the biological and nutritional 

 requirement of most species as well as economic studies to learn how to raise 

 them at a profit under various types and levels of farming and management. 

 Our long-range studies are intended to provide this type of information so true 

 "fish farming" of marine species can become a reality. 



Mr. Rogers. I do not think people realize this potential. I am glad 

 to see that you are making people aware of the revenues brought into 

 the Federal Government. I believe you said $2.7 billion, from natural 

 resources. 



Dr. Cain. Royalties from oil and gas, and sulfur, and this sort of 

 thing ; yes, sir. 



Mr. Rogers. Could you give us a projection as to what we may ex- 

 pect for the next 10 years and let us have that for the record ? 



Dr. Cain. We will provide it for the record. 



Mr. Rogers. I think it would be helpful to give us some idea of 

 what we may expect so we can relate it to your testimony.

Revenues Derived From the Outer Continental Shelf 



Natural resources (bonuses royalties, and irentals on oil, gas and sulfur) have 

 brought a total of about $2.7 billion into the Federal treasury. Following is a 

 breakdown of revenues from the Outer Continental Shelf for the past 2 years : 



Calendar years 



1965 1966 

 Royalties: 



Oil and condensate..- $80,408,174 $103,707,597 



Gas - 19,248,110 29,142,325 



Sulfur 3,197,532 4,128,691 



Salt./.V.V.V.V..". 8,724 8,924 



Total royalties 102,862,540 136,987.537 



Rentals 8,515,378 7,085,277 



Bonuses 33,740,309 209,199,893 



Total royalties, rentals, and bonuses. 145,118,227 353,272,707 



We can reasonably expect to collect an additional $3.5 billion over the next 

 10-year period.
