Title: Herring Restoration in PWS: Identifying Natal and Nursery Habitats 070782

Project Year and Number: 2007: 070782

Other Fiscal Years and Numbers for this Project: 2006: 060782

Principal Investigator (PI): Nate Bickford (University of Alaska Fairbanks)

Managing Agency: ADFG

Assisting Personnel: Brenda Norcross

Research Location: Prince William Sound

Restoration Category: Research

Injured Resources Addressed: Pacific Herring

Abstract: More information is required to understand the life history of Pacific herring and thus success of future enhancement experiments designed to improve the survival rate of juveniles into adulthood. Chemical analysis of trace element concentrations in otoliths can be used to identify geographic signatures of natal habitats used by fishes captured either as juveniles or adults. Because survival of the population is dependent on successful spawning, it is imperative to understand if distinct groups of herring are contributing to the success of the population. If most of spawning success comes from a distinct groups of herring we need to know which population survived and why. This will allow us to protect the most important populations and also identify those environmental variables needed to enhance other populations. With the information gained from this project, we will be able to identify other habitats that may be suitable for herring recolonization projects.
