HMSC Research Seminar-Decadal changes in habitat suitability for Pacific cod larvae in the Bering Sea and Gulf of Alaska

Speaker: Mary Hunsicker (NWFSC) and Ben Laurel (AFSC), NOAA

Topic: Decadal changes in habitat suitability for Pacific cod larvae in the Bering Sea and Gulf of Alaska

Recent warming trends have generated increased interest in the phenology of marine primary productivity. It is well established that ocean warming may alter the timing of phytoplankton blooms and cause a mismatch with the peak of fish larval production. However, the synergistic effects of regional environmental variables, physiology and phytoplankton phenology on larval fish survival have been less studied. In our presentation, we will share some work in which we and our colleagues combined experimentally-derived rates of larval survival in relation to water temperature with satellite remote-sensing estimates of chlorophyll a and sea surface temperature to predict habitat quality of first feeding Pacific cod (Gadus macrocephalus) larvae in two neighboring ecosystems; southeast Bering Sea (BS) and Gulf of Alaska (GOA). Our findings demonstrate how climate variability and mismatch between cod larvae and their food affect cod larval survival within and across regions in Alaska.
