Eastern Pacific Ocean Purse-seine Fishery Logbook and Landings Data, 1952-Present

U.S.-flagged purse-seine vessel logbook and landings data from the Eastern Pacific Ocean, collected from 1952 to the present. The Inter-American Tropical Tuna Commission (IATTC) manages the data collection, which includes records from vessels targeting tropical tunas and coastal pelagic species. Observer data for monitoring marine mammal interactions and bycatch are also included.

Use Cases

• Analyze historical fishing effort and catch composition based on logbook and landings records.
• Model population dynamics of tropical tunas and coastal pelagic species based on reported catch data.
• Assess marine mammal and bycatch interactions based on observer program data mentioned in the description.
• Study fleet dynamics and vessel behavior shifts from the Eastern Tropical Pacific to the western-central Pacific.

Strengths

• Data collection spans over 70 years, from 1952 to the present.
• Includes data from multiple vessel types and target species, as described.
• Integrates logbook, landings, and observer data from a recognized international commission (IATTC).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific fishery and reporting system.
