American Samoa Longline Fishery Trip Expenditure (2006 to present)

This is a time-series dataset for trip expenditure data for the American Samoa-based longline fleet from August 2006 to present. The dataset includes 10 variable cost items commonly associated with longline trips (not including labor costs). The cost items collected are: unit price, quantity used, and total cost estimates for diesel fuel, engine oil, bait, ice; 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 Pacific Islands Regional Office (PIRO) Observer Program.

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

Due to the low number of observations, the dataset is subject to confidentiality restrictions, and there may not be enough observations (= or >3) to produce a quarterly summary report.

Access database

Due to the low number of observations, the dataset is subject to confidentiality restrictions, and there may not be enough observations (= or >3) to produce a quarterly summary report.

Observers accompanied fewer than 10% of American Samoa-based longline fishing trips during the period 2006-2009, but observer coverage increased to 25% in 2010. The economic data collected through this program has been limited due in part to relatively low observer coverage of the American Samoa longline fleet.

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.
