Mr. Axdersox. As a result of this figuring; it would be a little- 

 less than that. 



You have seen the statement put out by the committee, the mem- 

 orandum put out by the committee with your statements here on. 



I wonder if all of these statements were figures that you people- 

 agreed on? 



Dr. White. I am not sure which memorandum that is, sir. 



Mr. Axdersox. I am having a difficult time keeping your figures 

 straight in my mind, and the more I listen, the more confused I am 

 getting. 



Dr. White. No, we have not seen this memorandum, sir. 



Mr. Axdersox. You have not ? 



Dr. White. No. Some members of my staff conceivably could have, 

 but I have not. 



Mr. Leggett. We do not normally share that with witnesses. 



Mr. Axdersox. Thank you, Mr. Chairman. 



Mr. Leggett. Thank you, Mr. Anderson. 



One thing we had to clear up at the time we adjourned, the testi- 

 mony was this morning that 20 percent of the overall porpoise sets 

 were involved with eastern spinners. I had some private colloquy 

 with Mr. Schoning as to whether or not that 20 percent also included 

 the other stocks upon which you have determined there would be 

 zero taking. 



Dr. White. Mr. Chairman, I agree that there is room for some 

 confusion in citing all of these percentages. I think it would be a 

 good idea if we let Dr. Fox address the question of the various per- 

 centages, mixed schools' relationship to the yellowfin tuna so we can 

 clarify the record on this, sir. 



Mr. Leggett. All right, Dr. Fox. 



Dr. Fox. Thank you. 



Mr. Leggett. Speak close to the microphone. 



Dr. Fox. These numbers are our averages for 1974 from the data 

 that was accumulated through September, 1976. 



The average percent of porpoise sets involving mixed schools is 

 49 percent. 



Of that, 23 percent was associated with eastern spinner schools, 

 and 26 percent were white bellied schools. There was some overlap, 

 but that was factored out to give these two numbers. 



Mr. Leggett. All right. 



Dr. Fox. In terms of catch figures, 58 percent of the yellowfin 

 catch on porpoise is taken with mixed schools; 23 percent of the 

 yellowfin catch is taken in mixed schools associated with eastern 

 spinners. 



Mr. Leggett. Twenty six percent ? 



Dr. Fox. Twenty three percent. 



Mr. Leggett. Of the catch ? 



Dr. Fox. The yellowfin tuna associated with porpoise is in mixed 

 schools with porpoise, including eastern spinners, and the number is 

 35 percent for mixed schools of eastern spinners and white belly, and 

 those add up to 58 percent. 



Mr. Leggett. Are there other species besides the eastern spinner 

 which is depleted which would constitute a maximized school of
