Data conflicts in fishery models: incorporating hydroacoustic data into the Prince William Sound Pacific herring assessment model

Bayesian stock assessment of Pacific herring in Prince William Sound, Alaska

The Pacific herring (Clupea pallasii) population in Prince William Sound, Alaska crashed in 1993 and has yet to recover, affecting food web dynamics in the Sound and impacting Alaskan communities. To help researchers design and implement the most effective monitoring, management, and recovery programs, a Bayesian assessment of Prince William Sound herring was developed by reformulating the curr...

The Prince William Sound Risk Assessment

After the grounding of the Exxon Valdez and its subsequent oil spill, all parties with interests in Prince William Sound (PWS) were eager to prevent another major pollution event. While they implemented several measures to reduce the risk of an oil spill, the stakeholders disagreed about the effectiveness of these measures and the potential effectiveness of further proposed measures. They forme...

Epizootiology of viral hemorrhagic septicemia virus in Pacific herring from the spawn-on-kelp fishery in Prince William Sound, Alaska, USA.

Both the prevalence and tissue titer of viral hemorrhagic septicemia virus (VHSV) increased in Pacific herring Clupea pallasi following their introduction into net pens (pounds) used in the closed pound spawn-on-kelp (SOK) fishery in Prince William Sound, Alaska. VHSV was also found in water samples from inside and outside the SOK pounds after herring had been confined for several days; however...

&on Vuldez Oil Spill Restoration Project Final Report Investigations of Disease Factors Affecting Declines of Pacific Herring Populations in Prince William Sound Restoration Project 98162 Final Report Sections: I. Field Survey of Diseases in Prince William Sound Herring

Pacific herring (ClupeupulZasz) population biomass in Prince William Sound declined nearly 80% from 1992 to 1994. Viral hemorrhagic septicemia virus probably contributed most to population decline in 1994. Viral prevalence in spring samples (n = 233-260/year) steadily decreased from 1994 to 1996 (4.7% 1.9% O.OO/), but prevalence increased to 15% in 1997 and 1998. Vial disease is acute (days to ...
