SILLIMAN: EXPERIMENTAL POPULATIONS OF TILAPIA MOSSAMBICA 



Utter, Harold 0. Hodgins, and Donald D. Worlund, 

 all of the Northwest Fisheries Center, National 

 Marine Fisheries Service, NOAA. The plan of the 

 experiment was reviewed by them and by Joseph 

 Felsenstein of the University of Washington, 

 Seattle, Wash. It is pertinent to note, however, 

 that some changes were made in the plan due to 

 developments during the experiment. 



My special thanks are due Alban R. Essbach of 

 the Arizona Game and Fish Department. He 

 generously shipped stocks of fish on two different 

 occasions. 



Experimental populations were maintained 

 during various periods by George F. Slusser, 

 Christopher E. Mathews, Martin G. Beam, Jimmy 

 R. Chrnaoski, and Judy A. Trauth. I also thank 

 George F. Slusser for furnishing the initial stock 

 of fish. All of these persons are present or former 

 members of the National Marine Fisheries Ser- 

 vice, NOAA (formerly Bureau of Commercial 

 Fisheries).
