dian Ocean. Free schools in these analyses included all 

 types of associations with marine animals. The propor- 

 tion of sets of the French fleet on other types of schools 

 and on resulting catches is not known. Cort (1992) pre- 

 sented such data for Spanish vessels, based on fishing 

 logbooks. Therefore, I used the observers data of the Sey- 

 chelles Fishing Authority (SFA) (Cort, 1992) for the ves- 

 sels of France, Spain, Japan, and USSR to assess these 

 values in the WIO. The percentage of sets on whale-asso- 

 ciated schools varied from 1.7% to 8.8% in 1986-90, the 

 percentage among positive sets was from 1.2% to 9.1%, 

 and the catch from such schools was 1.6% to 7.8% (cited 

 from Cort, 1992). These values are slightly lower than the 

 observer data I report in the present study (9%, 10%, and
