Otolith biogeochemistry reveals possible impacts of extreme climate events on population connectivity of a highly migratory fish, Japanese Spanish mackerel <i>Scomberomorus niphonius</i>.

ABSTRACT: Climate change, particularly extreme climate events, is likely to alter the population connectivity in diverse taxa. While the population connectivity for highly migratory species is expected to be vulnerable to climate change, the complex migration patterns has made the measurement difficult and studies rare. However, otolith biogeochemistry provides the possibility to evaluate these climate-induced impacts. Japanese Spanish mackerel Scomberomorus niphonius is a highly migratory fish that is widely distributed in the northwest Pacific. Otoliths biogeochemistry of age-1 spawning or spent individuals from three consecutive years (2016-2018), during which a very strong El Niño was experienced (2015-2016), were analyzed to evaluate the temporal variation of connectivity for S. nipho
