Abstract

ENGLISH: Logbook records of purse seiners and baitboats fishing for yellowfin and skipjack tunas in the eastern Pacific Ocean were used to prepare charts showing the distribution of catches by one-degree area and quarter of the year for each gear and regulation status, for the years 1975-1978. Changes in geographical distribution of the catch over the four-year period are described. Information on annual catch statistics and fleet composition by country is presented.
