Pacific herring (Clupea pallasii) and Pacific sand lance (Ammodytes personatus) are two forage fish species with different life history strategies that are ecologically important as a food source within the Sound. Her research suggests that they both have multiple spawning periods that are not in sync with each other and may occur at different times in different basins, even within the same species.
Hood Canal Basin is a particularly important area to study, as it often experiences insufficient oxygen in the water column to sustain life. “The question of under what conditions larvae persist within Hood Canal is an interesting one,” Godersky explains.
She plans to look at oceanographic data, including dissolved oxygen content, to see if there is a correlation between the presence of larvae and oxygen within all the basins—but is particularly interested in the results from Hood Canal. Godersky aims to complete her master’s degree by the end of summer and is proud to have spent her time in the Burke’s ichthyology collection.
