ABSTRACT 



The results of 546 days of trolling and watching for bird flocks and fish 

 schools are summarized In three categories based on distance from Islands. The 

 frequency of fish school sightings appears to be a function of the abundance of 

 birds, and was lower beyond 180 miles from land than within that range. Skipjack 

 were the dominant species In the open ocean; yellowfln were more abundant near 

 land In most Instances. There Is a seasonal pattern In the frequency of sightings, 

 possibly associated with the life patterns of the birds. In Island areas good 

 agreement was obtained between the abundance of fish schools and the abundance of 

 plankton. In the oceanic areas the agreement was not very good. Possible reasons 

 for the discrepancies are discussed.
