| Summary: | Climate-related changes in sea ice conditions in the Bering Sea affect the timing and magnitude of spring plankton blooms and likely has consequences for the survival of commercially important fish species during their early life history. Pacific cod may be particularly vulnerable to such changes because of their relatively discrete spawning period during the spring, yet modeling exercises have not examined this explicitly, likely because vital rate data do not exist for this species during larval/juvenile stages. We propose integrating experimental and modeling approaches to measure these vital rates and determine the recruitment potential of Pacific cod under two competing theoretical frameworks: 1) the Oscillation Control Hypothesis and 2) the Match-Mismatch hypothesis. Our models will consist of laboratory validated data on growth and survival responses of larval/juvenile stages of Pacific cod exposed to varying temperature and food regimes. Models will be designed to make spatially explicit maps of survival probabilities at monthly and annual scales using data taken from lab studies and coupling these with field data (available and modeled) on |
