Description
The goal of our project was to examine the feeding ecology of age-0 Pacific herring (Clupea pallasi Valenciennes 1847) within their nursery areas in Prince William Sound, Alaska. One of the many questions that led us to this goal was what defines the juvenile habitat and what influences within that habitat affect juvenile herring behavior and distribution. We were interested in the trophic interactions that juvenile herring encounter, in particular, their seasonal feeding behavior. Early hypotheses suggested that feeding dynamics in the spring and summer when zooplankton biomass is at its peak were critical to the success of the juveniles. Current work emphasizes fall and winter feeding behaviors as being important for the juveniles to survive to the next spring phytoplankton bloom (Paul and Paul 1998, Foy and Paul 2000).
