Abstract: Skipjack tuna (Katsuwonus pelamis) constitute an important
migratory species that contributes significantly to the economy
and the global fishery industry. Skipjack tuna play a vital role
in the marine ecosystem, particularly in tropical waters of the
western and central Pacific Ocean (WCPO). However, climate
change may affect the characteristics of fishery resources, leading
to substantial reallocation and reduction of the biomass of
this species in the WCPO. In this study, catch and effort data
for skipjack tuna were collected from a purse seine fishery and
subsequently analyzed in combination with remote-sensing environmental
variables and simulation data from climate models
under various scenarios. Generalized additive models were developed
to examine the relationships between environmental
variations and the species’ catch per unit effort and thus evaluate
the potential effects of climate change. The catch potential of this
stock was estimated under various greenhouse gas emission scenarios
(2015-2050) currently under consideration by the Intergovernmental
Panel on Climate Change (IPCC). The highest catch
potential was associated with the highest greenhouse gas emissions,
whereas the catch potential remained relatively stable under
the scenario with lower emissions. To sustainably utilize skipjack
tuna as a resource, the impact of climate change on the stock
under various global warming scenarios should be considered in the assessment and management of fisheries for this species.
