with aquaculture even as tliey have with agriculture in the use of 

 human waste. 



I hope that it will keep us from overreacting. 



Thank you, Mr. Chairman. 



Mr. DiNGELL. Thank you, Mr. Keith. 



Mr. Kyros ? 



Mr. Ktros. I thank the gentleman. 



I was interested in what you said about Maine, of course. Did you 

 mean, for example, that if discharge from one of these nuclear plants 

 was going into Sheepscot Bay near Wiscasset, you could dam that dis- 

 charge somehow, and utilize it ? 



Dr. Ketchum. Yes. As I remember that part of the coast there 

 are long lagoons which you could utilize either for growing lobsters 

 or other forms in the water where they now grow only about 4 months 

 of the year because of the cold water. You might indeed get other 

 things to grow there which are no longer able to grow because of the 

 cold winter. 



]Mr. Keith. Will the gentleman yield ? 



I think you hinted at that before when you said we could warm 

 the waters of Maine so that some of us could swim there. 



Dr. Ketchum. That is one of the advantages. 



Mr. Kyros. Doctor, the other day I had occasion to climb Mt. 

 Katahdin on snowshoes. At about the 4,000 foot level I met someone 

 by the name of Charles Hollister. He said he was an oceanographer 

 testing for mercury and nitrates in the snow. 



Dr.KETCHUM. Is he? I didn't know what he was doing up there. 



Mr. Ktros. We were standing on a sterile pond up there where, 

 I must admit, it was kind of incongruous to see him. He said he was 

 going to make a trip to the Himalayas next year. 



Dr. Ketchum. He is also a famous mountain climber. He has 

 climbed some of the mountains in the Antarctic. 



Mr. Kyros. I went last summer to New Meadows, where they are 

 growing oysters. Do you think that could become a profitable business 

 up there ? 



Dr. Ketchum. It certainly is in Japan. At present state of our 

 demands for food it is profitable when and only when a high quality 

 product is produced. So that in Japan the profitable aquaculture con- 

 sist of oysters, shrimp, other delicacies. There are a few j)arts in the 

 Far East where mullet is grown in aquaculture, and they may consider 

 it a delicacy, I am not sure that I would. Most of the aquaculture that 

 is profitable today is high quality, high priced material. 



Mr. Kyros. Thank you very much. Doctor. 



Thank you, Mr. Chairman. 



Mr. Dixgell. Doctor, the committee is grateful to you. 



The Chair is going to recognize a good friend and counsel, 

 Mr. Everett. 



Mr. Everett. Thank you, Mr. Chairman. 



Dr. Ketchum, on two occasions you referred to the expression that 

 the ocean should be an interim or temporary solution to our waste 

 disposal problem. 



I was wondering if you had formulated in your mind the time when 

 there should be a complete ban on ocean dumping of these waste 

 materials ?
