Juvenile Salmon and Pelagic Ecosystem Trawl Surveys in Pacific Waters

Fisheries and Oceans Canada surface water trawl surveys have been conducted since 1992 in coastal waters of British Columbia, Washington, Oregon, Alaska, and the Gulf of Alaska. The data contain fishing, catch, and biological information, with research focus evolving from salmon migratory patterns to broader pelagic ecosystem components.

Use Cases

• Analyze juvenile Pacific Salmon migratory patterns using catch information and biological data from 1992-2002 surveys.
• Study growth and physiology of juvenile Pacific Salmon using biological information recorded in surveys from 2003-2016.
• Model pelagic ecosystem components by integrating catch information and biological data from surveys conducted since 2016.
• Compare fishing and catch information across different large marine ecosystems like the Gulf of Alaska.

Strengths

• Data collection spans over 30 years, starting in 1992.
• Surveys cover a broad geographic area including coastal waters of four regions and the high seas of the Gulf of Alaska.
• Research focus has evolved across three distinct periods, providing longitudinal context.

Limitations

• Survey location and timing vary between years due to changes in research priorities.
• Data availability varies by large marine ecosystem, potentially creating gaps for specific regions.
• Specific sample sizes, row counts, and column details are not provided in the input.
