Mr. Leggett. Thank you very much. 



Mr. Eisenbud, do you have anything else to volunteer ? 



Mr. Eisenbud. No, Mr. Chairman, I do not think so, except to offer 

 for the record those reports which were mentioned by Dr. Chapman, 

 and a copy of the letter that we did send to the Maritime Administra- 

 tion, recommending that vessels not be permitted to transfer, or that 

 bonds be imposed on transfers, if they are permitted.

Report on the Tuxa-Porpoise Cruise to the Marine Mammal Commission 



(By Warren E. Stuntz, Ph. D.) 



The tuna-porpoise behavior cruise, undertaken as a result of the Marine 

 Mammal Commission's 1975 workshop, was a cooperative effort between the 

 University of California at Santa Cruz (USC), funded by the Marine Mammal 

 Commission, San Diego State University (SDSU), and the Naval Undersea 

 Center (NUC), funded by the National Science Foundation (NSF), the 

 National Marine Fisheries Service, and the tuna industry. The following 

 personnel participated : Dr. Kenneth Norris, UCSC ; Dr. Warren E. Stuntz, 

 UCSC: Dr. Frank Aubrey, UDSU : Dr. Edward Mitchell, Environment Canada; 

 Dr. William I'errin, NMFS : Dr. Nancy Lo, NMFS ; Mr. James Coe, NMFS ; 

 Mr. David Holts, NMFS; Mr. William Rogers, UCSC; Mr. Phillipe Vergne, 

 Living Marine Resources ; Mr. Joseph Thompson, Sr., Seavision Productions ; 

 Mr. Joseph Thompson, Jr., Seavision Productions; Ms. Karen Pryor, Porpoise 

 Rescue Foundation ; Mr. Stephen Leatherwood, Naval Undersea Center ; Mr. 

 Donald Ljungblad, NUC. 



Two vessels were employed for the cruise, the tuna purse seiner Elizabeth 

 C. J. and the NOAA research vessel David Starr Jordan. The Jordan, Milton 

 Roll, Master, left San Diego on 5 October 1978 and the Elizabeth C. J., Manuel 

 Jorge, Master, left San Diego on 11 October 1976. 



During the first leg of the cruise, 14 data collection sets and 7 normal fishing 

 sets were made by the Elizabeth G. J. During these 21 sets a total of 12 

 porpoise, 11 Stenella attenuata and 1 Stenella longirostris, were killed. The 

 data collection sets were as follows : 



The Jordan left after 2 November for Manzanillo, Mexico, to refuel and to 

 make changes in scientific personnel. On her return and rendezvous with the 

 Elizabeth C. ./., it was planned to do a tagging set after which the Jordan 

 would follow the radio tagged animals for as long as possible before returning 

 to San Diego. Difficulties with all the tracking receivers resulted in the 

 scientists having to settle for simple observation of the set.

During standard sets, scientific personnel were placed at different vantage 

 points to maximize data collection. Personnel on the tuna seiner observed 

 surface behavior and dive frequency, and personnel in the water recorded
