Project Information

Title: Diet, Trophic Interactions, and Historical Trends in Occurrence of Salmon Sharks, Sleeper Sharks, and Spiny Dogfish in Prince William Sound and the Eastern Gulf of Alaska 00396

Project Year and Number: 2000: 00396

Other Fiscal Years and Numbers for this Project: 2002: 02396, 2001: 01396

Principal Investigator (PI): Lee Hulbert (Alaska Department of Fish & Game)

Managing Agency: NOAA

Assisting Personnel: Jeep Rice

Research Location: Prince William Sound, Eastern Gulf of Alaska

Restoration Category: Research

Injured Resources Addressed: Not Specified

Abstract: The revised proposal will investigate spatial and temporal movements, residency, diet composition, ecology, and trophic impacts of salmon sharks and Pacific sleeper sharks in Prince William Sound and will quantify refinements to shark parameters in the ECOPATH model (Project /330). The project will assess evidence of ecological implications of shark populations on the recovery of injured species through fatty acids and stable isotope tracer analyses and use of simulations based upon the refined ECOPATH model. Acoustic and satellite-linked telemetry will be utilized to determine shark movements and migrations, critical feeding areas and depths, and behavioral data. The research will address the role of the predominant shark species in the dynamic trophic structures in the Prince William Sound region.
