Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. I believe the necessity exists for studying whether skipjack and tuna remain in specified localities at any certain period during their development, if coastal schools differ from migratory schools, and if a single large group migrates in the warm waters of the vast Pacific. In order to do this, however, it is important to study by some means the age of fish caught in the various areas. One method is by examining the rings appearing on scales and vertebrae. I feel that the selection of Palau as a principal research point is ideal as skipjack and tuna can be caught there throughout the year and it is near their presumed spawning grounds.
