How herring learn from their elders


Young herring learn migration behavior by joining up with older fish, according to a new paper co-authored by Puget Sound Institute Lead Ecosystem Ecologist Tessa Francis. The paper, published this month in the ICES Journal of Marine Science, showed how this behavior leads to greater spatial variability in biomass, and that fishing could disproportionately affect fish populations, including Pacific herring (Clupea pallasii), with this behavior.
