ACTION:

Notice of public meeting.

SUMMARY:

NMFS will convene a workshop on walleye pollock in Alaska for the purposes of synthesizing ongoing research, building and strengthening collaborations, and highlighting topics which need more attention. The focus will be on biological and ecological scientific research.

DATES:

The workshop is open to the public from January 14, 2025-Jan 16, 2025 from 9 a.m. to 5 p.m. Pacific standard time. Please see SUPPLEMENTARY INFORMATION for the daily meeting agenda.

ADDRESSES:

The meeting will be a hybrid format with the in-person component in Room 2076, Building 4, Alaska Fisheries Science Center, Western Regional Center, Seattle, WA. The virtual component will be held on Google Meet at: https://meet.google.com/wwy-yxuo-usf.

Daily Meeting Agenda

The agenda is subject to change; all times are in Pacific Standard Time (PST), and are approximate and may be changed at the discretion of the coordinators. Presentations are grouped by themes, and can focus on different large marine ecosystems (LME) in Alaska, including the Gulf of Alaska (GOA), Bering Sea and Aleutian Islands (BSAI), the Northern Bering Sea (NBS), and the Eastern Bering Sea (EBS).
