Hawaii Longline Fishery Trip Expenditure (2004 to present)

This is a time-series dataset of trip expenditure data for the Hawaii-based longline fleet for the period August 2004 to present. The data collection includes 10 variable cost items commonly associated with Hawaii longline trips (not including labor costs). These cost items are: unit price, quantity used, and total cost estimates of diesel fuel, engine oil, bait, ice, swordfish certificates (shallow-set only), and lightsticks (shallow-set only); and total cost estimates for gear, provisions, and communications. Additional information about the operator and crew are also included. These data are collected on a routine basis through a collaboration between the Pacific Islands Fisheries Science Center (PIFSC) Economics Program and the Pacific Islands Regional Office (PIRO) Observer Program. The economic data collection program intends to collect data from all observed trips. Currently, observer coverage rates in Hawaii based pelagic longline vessels are 100% of shallow sets that target swordfish and 20% of deep sets that target tuna. Since the economic data collection project was implemented in August 2004, economic data have been collected for over 1,900 longline fishing trips. Minling Pan is the lead for this project.

The objective of this data collection is to obtain baseline economic information on and monitor changes in key economic indicators of the Hawaii-based longline fishery.

Access database

Participation of the survey is voluntary. Given the high response rates, the sample was considered representative and non-biased.

The economic data collection program intends to obtain data from all the observed trips. Currently, observer coverage rates for the Hawaii-based pelagic longline fleets are 100% of shallow sets that target swordfish and 20% of deep sets that target tuna. The response rate increased from about 44% in 2004, the first year of the program, to 69% in 2007, it has dropped slightly in recent years.

The quality of the data was controlled throughout the data life cycle including data collection, data entry, data cleaning, and data storage. Data were collected following rigid statistical method (e.g. interviewers were trained to get familiar with the questionnaire for in-person survey). Data entry file was developed to minimize data entry errors, including setting data ranges, embedding skip patterns, and multiple choice questions were set with pre-determined choices. Data were cleaned with logic checking, skipping patterns, and outliers. Data files were stored in PIFSC’s server with password protection.

No delay expected

These data are Sensitive (business information). Efforts to disseminate can be arranged upon request, but the data are currently out of scope for the Data directive.

Data is securely stored in PIFSC's server with password protection.

Only staff who work on the project can access to the data.

After the data were collected through in-person interview, data were entered into the data entry file in Access database. Then the entered data were cleaned with logic checking, skipping patterns, and outliers. Finally the cleaned data were used to generate data report.
