LENGTH (CM) 



Figure 8 (Continued) 



striped dolphins might carry more tuna and be cap- 

 tured more frequently than schools composed of 

 adult animals. If the bond between yellowfin tuna 

 and dolphins is related to size and hydrodynamics 

 as suggested by Edwards i 1992) then it may be that 

 the smaller striped dolphins are hydrodynamically 



more suitable for this association. Juvenile schools 

 of striped dolphins are made up of animals that are 

 about the same length as schools of spotted or spin- 

 ner dolphins for which the tuna-dolphin association 

 appears to be the strongest.
