| Abstract: | In order to study the relationship between daily increment of statolith and environment of neon flying squid (Ommastrephes bartramii) for different cohorts in the North Pacific during feeding ground, we explore the relationship between daily increment of statolith microstructure and environmental variables by gradient forest method (GFM) and generalized additive model (GAM) based on the samples collected in the North Pacific from 2010 to 2016. The results show that the life cycle of O. bartramii is about one year. The age of the autumn cohort ranges from 165 d to 345 d, and the age of winter-spring cohort ranges from 95 d to 271 d, respectively. Sea water temperature at the depth of 100 m (Temp_100), sea surface temperature (SST), sea surface salinity (SSS) and mixed layer depth (MLD) are the key environmental variables for the daily growth of autumn cohort. Temp_100, MLD, sea surface height (SSH) and chlorophyll a concentration (CHL) are the key environment variables for the daily growth of winter-spring cohort. GAM analysis shows that the daily increment width of statolith is significantly correlated with the key environmental variables selected by GFM (p<0.01). Key environmental variables of different cohorts suggest that the growth of O.bartrarnii is significantly affected by water temperature and prey abundance. |
