Abstract：Scomber japonicus is one of the main target species of fishery in northwest Pacific.Its re-source recruitment often fluctuates significantly due to the impact of climate change and other factors.To study the impact of climate change on the change of S.japonicus resource northwest Pacific,and analyze the general change rules of transportation distribution and resource recruitment under abnormal climate conditions,the individual based early ecological dynamics model of S.japonicus in northwest Pacific was used to simulate the distribution and recruitment of S.japonicus resource in northwest Pa-cific from 1997 to 2010.The differences of transport and distribution paths and changes of recruitment amount of larvae fish under different climatic conditions in El Niño year(2002),normal climate year(2006)and La Niña year(2010)were compared.The simulation results showed that the resource dis-tribution and recruitment of S.japonicus in northwest Pacific have fluctuated significantly in the simu-lated 14 years,and the resource distribution and recruitment of S.japonicus resource are different un-der different climatic conditions.our findings indicated that the changes of marine environments inclu-ding temperature,ocean current among others caused by climate change impact the resource of S.ja-ponicus.
