The largest shark in this study (602 cm TL) represents the largest measured shark on record worldwide. Reliably measured sharks ranged from 126–602 cm total length (TL) and 16–2530 kg total weight. Population trend analysis indicated that the relative abundance of white sharks in the region has remained relatively stable, but parameterization of a 75% increase in observer effort found evidence of a minor decline since 2002. Observations occurred in all months, excluding October-January in the north (Russia and Republic of Korea) and July-August in the south (China, Taiwan, Philippines, and Vietnam).
Records comprise reports of bycatch in commercial fisheries, media accounts, personal communications, and documentation of shark-human interactions from Russia (n = 8), Republic of Korea (22), Japan (129), China (32), Taiwan (45), Philippines (1) and Vietnam (3). This study provides a meta-analysis of 240 observations of white sharks from the Northwest Pacific Ocean between 19.
Knowledge of white shark biology and ecology has increased recently based on research at known aggregation sites in the Indian, Atlantic, and Northeast Pacific Oceans however, few data are available for the Northwest Pacific Ocean. White sharks are highly migratory apex predators, globally distributed in temperate, sub-tropical, and tropical waters.
