ging was mailed to individuals that had participated 

 in the program. This mailing list consisted of names 

 of billfish anglers, most of whom fished in the east- 

 ern Pacific or off the east coast of Australia. 



In the annual reports for 1969, 1970, and 1971, a 

 postcard was enclosed requesting information on 

 the amount of fishing effort and catch. The billfish 

 angler was asked to recall the number of days of 

 billfishing and the number of billfish caught by 

 species. The anglers were requested to give an 

 "honest" answer and told that information on zero 

 catches was important. The technique of postcard 

 survey has been the subject of considerable con- 

 troversy. The California Department of Fish and 

 Game has used this technique and a number of re- 

 searchers have published on the results of this type 

 of survey (Calhoun, 1950, 1951: Clark, 1953; 

 Pelgen, 1955; Abramson, 1963; Jensen, 1964). 



Hayne reported that it is difficult for a fisherman 

 to remember precisely his catch of the previous 

 year. However, with regard to billfishes, the fre- 

 quency at which the average billfish angler partici- 

 pates in the sport is limited and the annual catch of 

 billfish per angler is small. Billfish are "trophy fish" 

 and the author believes that the average billfish an- 

 gler can recall within close limits the number offish 

 caught during the previous year and the number of 

 days he participated in the fishery.
