Paperback. Condición: New. Print on Demand. This book examines the distribution, abundance, and movement of skipjack tuna in the Pacific Ocean. Through data collected between 1964-1967 from Japanese tuna longline catches, the author analyzes the relative abundance of skipjack tuna across the vast expanse of the ocean, providing insights into their behavior and migration patterns. The author discovered that skipjack tuna tend to concentrate around the east-central equatorial Pacific, and that their movements follow the circulation patterns of the major ocean currents: counterclockwise in the Southern Hemisphere and clockwise in the Northern Hemisphere, except for the counterclockwise flow in the Eastern Pacific. Surrounding these patterns are smaller, localized movements specific to each population group. The book contributes to our understanding of skipjack tuna population dynamics, which has implications for the sustainability and management of this crucial species within the global ecosystem. By tracing their migratory routes, the author sheds light on the potential connectivity between different populations and their resilience to environmental changes.
