A salmon diet database for the North Pacific Ocean.

Area of Science:

• Marine Biology
• Fisheries Science
• Database Management

Background:

• Salmon diet data are fragmented across numerous sources.
• Understanding salmon ecology in the North Pacific Ocean requires consolidated data.
• Existing data lack a standardized structure for comprehensive analysis.

Purpose of the Study:

• To create an open-access relational database for salmon diet information.
• To standardize diverse salmon diet data for accessibility and analysis.
• To support ecological research on North Pacific salmon populations.

Main Methods:

• Systematic literature review of 62 sources (peer-reviewed and gray literature).
• Data extraction and standardization into a common relational database structure.
• Inclusion of salmon biological parameters, prey data, and environmental variables.

Main Results:

• The database contains 21,862 salmon diet observations.
• Data cover 907 unique spatial areas in the North Pacific Ocean.
• Data primarily span two periods: 1959-1969 and 1987-1997.

Conclusions:

• The database provides a centralized resource for North Pacific salmon diet research.
• Facilitates studies on salmon foraging, productivity, and marine survival.
• The database is expandable as more data become available.
