Research Location: Prince William Sound

Restoration Category: Monitoring

Injured Resources Addressed: Pacific Herring

Abstract: Past studies have documented damage from oil exposure in adult herring, hatching success of embryos, and levels of physical and genetic abnormalities in larvae. The PWS herring spawning population has drastically declined since 1993, and pathology studies implicated Viral Hemorrhagic Septicemia (VHS) and Ichthyophonus as potential sources of mortality as well as indicators of stress. The project will continue to provide estimates of spawning herring abundance and investigate the lethality of suspected pathogens and the role of environmental contaminants in disease transmission through laboratory and field studies.

Datasets:
EVOSTC Data Archive: Diver estimates of herring egg numbers in 0.1m2 quadrats. Geocoded transect locations for several types of near shore transects. Ancillary data include primary vegetation type and substrate in quadrats, physical characteristics of transect locations, and meteorological observations. Related ADFG data includes age/sex/size data and abundance. RBase databases = primary archive. Summaries and results of queries in Lotus 4.0 and Excel 5.0 Availability: All egg count data for 1984,85,88-92,94-95 are available on request. Current year data are preliminary. ASCII data files have been provided to SEADATA project for all years prior to 1995.
