Scope of Work:

The goal of this project is to create new partnerships and collaborations for the fisheries research program being conducted at the Prince William Sound Science Center. Specifically, the long-term Prince William Sound (PWS) Science Center/Dauphin Island Sea Lab fisheries research program will partner with the Pacific Ocean Shelf Tracking (POST) project to deploy a large-scale acoustic array in PWS that will become a significant component of the POST project. We also will partner with Kintama Research for a public workshop and PWSSC staff training that will expand ourlocal capacity to effectively and efficiently design and deploy acoustic arrays. This project will also create new collaborations and synergise with efforts of Ocean Tracking Network (OTN) and the Tagging Ocean Predators Project (TOPP) in PWS. We will achieve our goal using funding from the PWS Oil Spill Recovery Institute and in-hand equipment and/or funds from three other partners (Ocean Tracking Network, Rasmuson Foundation, and PWSSC) to match a grant from POST.

The proposed project includes three main components: a) a workshop by Kintama Research on designing large-scale telemetry arrays; 2) training of PWS Science Center personnel by Kintama Research on how to assemble and deploy large-scale array installations; and, 3) acoustic tagging and tracking of lingcod. With assistance from Kintama Research, we will deploy across the mouth of Port Gravina an acoustic array consisting primarily of VR3 underwater receivers. Two smaller arrays of VR2W underwater receivers will also be deployed at Gravina Island and Gravina Rocks, two sites located near the VR3 array.

Once the arrays are in place, we propose to capture and tag lingcod with acoustic transmitters in and around the arrays, and track their movements and residency in Prince William Sound. Lingcod, a bottom fish species unique to the coastal waters of the Pacific Coast of North America, support an important commercial and recreational fishery. Because of their depressed stock sizes, lingcod are currently a species of critical concern to fisheries managers throughout the Pacific Coast. The project would also rely on data from acoustic arrays being installed in 2009 by Ocean Tracking Network at the entrances to Prince William Sound to detect lingcod movements out of and back into the Sound. This combination of projects will further develop a comprehensive, ecosystem-based understanding of the importance of lingcod within the North Pacific Region and will increase the scope and capacity of POST for monitoring fish movements in Alaska.
