| Abstract |
Climate change is increasingly affecting marine organisms at both global and regional scales. Understanding how individual-level metabolism responds to climate change is crucial for elucidating the mechanisms driving population dynamics. This study aims to evaluate how future climate change affect the physiological activities, growth, and reproduction of small yellow croakers Larimichthys polyactis, a key commercial fish species in China Sea, through the lens of individual energy budgets. We applied the Dynamic Energy Budget (DEB) model to investigate the effects of environmental conditions (e.g., temperature, salinity, and food density) on the growth, development, and reproduction of fish individuals under different climate scenarios. The results showed that, in most climate scenarios (RCP2.6-2100, RCP4.5-2050, RCP8.5-2100), the energy allocated to assimilation, mobilization, and maintenance in small yellow croakers would increase, leading to faster growth and enhanced reproductive potential. However, under the extreme warming scenario (RCP8.5-2100), their growth slows down, and reproductive strategies would shift towards extended spawning seasons with lower intensity. Additionally, the energy dynamics of smaller individuals are more inclined to change due to climate change compared to more matured individuals. These climate-driven changes in physiological activities related to growth and reproduction might significantly impact population dynamics, introducing considerable uncertainty in the assessment and management of small yellow croaker resources. This study could help to assess the impact of climate change on population continuity and thermal physiology of important marine species. The methods could also be extended to other species and marine ecosystems, which could benefit the conservation and management of marine fisheries under future climate change. |
