摘要： Environmental changes greatly affect fish body condition, but impacts on many species are often unknown. We investigated the relative condition factor (Kn) of Conger myriaster in relation to abiotic/biotic variables in Haizhou Bay, southwestern Yellow Sea, China. We developed generalized additive mixed models (GAMMs) to analyze the time-lag effects of their responses to external factors and statistically evaluated their influence on Kn in newly recruited and juvenile individuals. Accordingly, we predicted the Kn under future climate projections for SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5. The results revealed a 5-month lag for both life stages to the El Ni & ntilde;o 3.4 index (equatorial Pacific sea surface temperature anomalies), a 1-2 week lag for sea surface temperature, and no lag for food availability. El Ni & ntilde;o 3.4 was the primary driver for newly recruited individuals, while sea temperature was most influential for juveniles. Food availability significantly impacted Kn for both stages. Predictive models suggest a thermally induced Kn decline for newly recruited individuals across all climate scenarios. Juveniles showed more resilience to global warming with stable Kn values across all scenarios until 2040, followed by rapid declines under SSP3-7.0/SSP5-8.5 scenarios. Our findings demonstrate life-stage-specific time-lag responses to environmental shifts in C. myriaster.
