Mr. KoczY. Yes. 



Senator Lausche. To what extent have tliey discovered areas of tisli 

 through the researches that have thus far been made and what are your 

 expectations of the potentials in this field? 



Mr. KoczY. In order to discover tish? 



Senator Lausche. Yes. That is, the farniint^ of tish and so on. 



Mr. KoczY. We at Miami have worked mainly on shrimp in the 

 Tortuga area which covers certainly one of the most valuable fish 

 in the States and we are studying billfish in the straits and in the 

 Caribbean. But our range of investigatiton is very restricted because 

 we have only a small, 76-foot vessel. 



Senator Lausche. You stated in your paper that tuna ai-e usually 

 found at mount tops. 



Mr. KoczY. That is a result of the investigation made by the Tuna 

 Commission, and Dr. Schaefer, specifically. 



Senator Lausche. What does that sort of portend? You say we 

 should make studies 



Mr. KoczY. When we know more about where sea moimts are, fish- 

 ermen can find more places where tuna is found and fishing for tuna 

 becomes more economic. 



Senator Lausche. And I suppose this general principle which you 

 apply to tuna may become applicable to all other attributes of the 

 ocean. 



Mr. KoczY. That is right. 



Senator Lausche. That is all I have. 



Mr. KoczY. Thank you. 



Th Chairman. Dr. Brown ? 



Dr. Brown is of the California Institute of Technology, the Division 

 of Geological Sciences. 



Dr. Brown, you are also chairman of the Committee on Oceanog- 

 raphy of the National Academy of Science ? 



Mr. Brown. That is right.
